I have taken as many sources as I could find as far as factory load
data and compiled into one document for easy reference for 155gr
and some 200gr bullets. See attached

Those bullets are what I would have expected their FMJ bullets to look like instead of hollow points. What were you shooting the bullets into ? The only bullets I have to load are 155gr Hornady XTP and 155 gr Xtreme Rounded Flat Nose Copper
coated bullets.

I have discussed the Accurate Arms load data for 155 gr in the Hornady load manual with their ballisticians and they concede they made some big mistakes with the AA#7 data and have withdrawn their published data and are duplicating the current Accurate Arms data for their 155gr XTP bullets.
This concerns only the AA # 7 powder.

Since Accurate Arms shows the highest performance with their #9 powder with the 155gr bullets, The Hornady ballistician stated that the very max velocities would be with a powder
between #7 and #9 since AA points out that their pressures with #9 are less than SAAMI max and that the velocities are limited by case capacity.

A7 Target Loads with 180 gr Plated

I went to the range today and am very pleased with the results. I am looking for a good target/IDPA load, and I wasn't looking to push velocities at all. Plated bullets do not respond well to high pressures and velocities. I have used Blue Dot extensively in the past - with great results. But I do not like the report, flash, and dirtiness of Blue Dot.

All charge weights shown were satisfactory altough two charge weights stood out as more precise. A7 is a clean-burning powder and exhibits milder felt recoil compared to Blue Dot with the same projectile and velocities. Pressure symptoms were non-existent for all weights as determined by max case expansion and other observations.

Firearm: G20
Temp: 35
Elevation: 3000
Bullet: Berry's MFG 180 gr FP plated DS
Brass: Starline
Primer: CCI 300
Powder: Accurate No. 7
COL: 1.26"
Crimp: light
10 shot strings

9.7 grains
Average 1055
Std Dev 12.4

9.9 grains
Average 1080
Std Dev 10.6

10.1 grains
Average 1098
Std Dev 13.9

10.3 grains
Average 1105
Std Dev 16.4

10.5 grains
Average 1140
Std Dev 11.7

9.9 grains and 10.3 grains demonstrated the highest precision - despite the fact that the 10.3 grain load had the highest standard deviation on velocity. Blue Dot groups better for me with this bullet, but these charges are sufficient to score "down 0" hits on IDPA targets.

I'm probably going to run with 10.3 grains for IDPA after I test a few more dozen rounds. That is pretty stout for competition (power factor = 198,900) considering a lot of guys are running 115 grain 9mm pills @ 1100 fps to barely make minimum power factor in the SSP division.

I am looking at the Accurate load data chart (just downloaded an updated version) and I can't find a load for 155gr lead. There is 140gr and 170gr but no 155gr.

I use Accurate #7 for all my hand loads. Currently I am looking for load data for 155gr Meister lead rounds: P/N RB-10-155RN, to be shot out of my G20C with a Stormlake 6" barrel.

There is load data for the 40SW, but I don't know if I should use load data from one caliber to another (yes, I know 10mm is .40). So any one here have an idea? Would it be acceptable to use the .40SW load data and work from there?

It should be ok to use .40 data. I would start with the max load listed for the forty and work up from there until you reach the desired outcome.

Just checking in to see what 10Ringers have cooked up using AA#7 and Hornady's 200gn FMJ-FP.

Looking for recommendations on loading these hot in once-fired brass (Starline).

Thanks!

Carphunter,

All things being equal, most all my handloaded 10mm's seem to run better at 1.250 to 1.255, but that's with Montana Gold 180 grain CMJ's or JHP's. (When experimenting/checking OAL, I found Double Tap's OAL to easily vary between 1.243 - 1.260, but still seemed to feed fine.

(My stock Glock barrels will eat just about anything, but ruin the brass for reloading.)

155 gr XTPs with Accurate No. 9

Ran some new loads over the chrony today. Respectable results. No issues.

Firearm: G20 with stock spring and barrel
Temp: 85 low humidity
Five shot average except for last three strings were 10 shots each. Velocities were not corrected to the muzzle.

Bullet: Hornady 155 gr XTP
Case: Starline
Primer: CCI 350
Powder: Accurate #9
COL 1.25"

14.3 gr
Average velocity: 1293
ME: 575

14.6 gr
Average velocity: 1309
ME:590

14.9 gr
Average velocity: 1332
ME: 610

15.2 gr
No data - chrony errors

15.5 gr
Average velocity: 1370
ME: 646

15.8 gr
Average velocity: 1401
ME: 675

16.0 gr
Average velocity: 1415
ME: 689

Notes: Accurate's max is 15.9 gr with a standard primer @ 32,700 PSI. I elected to go with a mag primer to ensure a good burn with that much powder. With the mag primers, I suspect that the pressures were a bit higher. They were getting warm (as noted by case expansion) by 15.8 gr. I suspect that bumping another 3-5 tenths would not be an issue, but case volume is about maxed at 16.0 gr.

The starting load was 50 fps faster than what Accurate was reporting from a 5# barrel. The top velocity was very close to book. I may try these with standard primers to see how they run. As is typical with A9, very clean burn. Little powder residue. These have a pretty pronounced recoil at 15.5 gr + and quite a bark. No issues with groups @ 15 yards.

That is great info. I load 155gr XTP on top of 15gr of #9. I don't have a chronometer, so it is great to see real world data. The only difference with my load is that I use CCI 300. I wonder what the difference is?

Thanks again for the data.

*edit* Have you ever loaded up 180 or 200 gr XTP with #9?

G20 w/ LW 5.2" bbl.

CCI 350 primers, Starline brass, 200g Truncated cone hardcast.

12.5g AA#9, 1163fps.

CCI 350 Primers, Starline brass, 180g FMJ,

13.2g AA #9, 1163fps.

Yeah, they both posted the same velocity, avg. for 4 shots. Was trying these w/ a compensator, but it didn't make any difference in velocity on another load, so I don't know how much it influenced these. Not expecting it did much.

Accurate No. 5 and Nosler 150 JHPs

I found some 150 Noslers on sale a few months ago so I snatched some up. I thought I'd work up a soft shooting load using Accurate No. 5. I like to have some light recoiling loads onhand for the occasional shooting companion that doesn't like recoil. I did not at all want to push things with A5 powder.

Firearm: Gen 3 G20 with stock barrel and recoil spring assembly.

All averages were 10 shot strings except the first (5 shots).

All weights hand weighed and verified with check weights.

Temp: 50

Brass: used Starline
Primer: CCI 300
Bullet: Nosler 150 gr JHP
Powder: Accurate No. 5
COL: 1.25"

9.1 Grains
Average velocity: 1105
ME: 407

9.4 Grains
Average velocity: 1173
ME: 458

9.6 Grains
Average velocity: 1214
ME: 491

9.8 Grains
Average velocity: 1220
ME: 495

10.0 Grains
Average velocity: 1263
ME: 531

The point of impact started climbing as charge weights increased. Best groups were at the lowest charge weights. Extreme spreads and groups opened up with increasing charge weights. I am of the conclusion that loading closer to starting loads is best groups.

All functioned without issues.

200 gr XTP Over Accurate no. 9

In years past, I had done workups with my supply of A9 powder purchased a few years ago. It was made in Belgium. Most of you know that Accurate now has powders produced in the USA (I believe this is also true for A5 & A7).

The made in USA powder is a little denser and has a totally different look to it. The Belgium stuff was a dull, dark color of the tiniest little spheres. The USA powder is dark, but shines in the right light. It is also tiny, but is somewhat of a flattened ball. Thankfully it meters as well as the Belgium lots.

I wanted to do a re-test with 200 grain XTPs to see if much had changed. The Belgium lots were noticeably temperature sensitive. Accurate claims that the new formula is better in that regard. This test seems to back that up.

The Belgium powder that was tested at 90F ran WAY faster than comparable loads of the Belgium powder tested at 50F; with temperature being the only significant variable.

All other variables were the same except for the temperatures noted. The new lots tracked very closely to what the Belgium powder lots did when tested at 90 degrees.

Firearm: Gen 3 Glock 20 with stock barrel (4.6") and RSA
Temp: 65F
Elevation: 3200 feet
Brass: Starline
Primer: WLP
COL: 1.26"
Bullet: Hornady 200 gr HP/XTP
Powder: Accurate no. 9 (hand weighed and verified with check weights)
Velocities were 10 shot averages not corrected to the muzzle.

Caution! These loads are less than Hornady max data, but some do exceed Accurate's max load of 12.5 grains. If you choose to reproduce these loads, please reduce to Accurate's starting load of 11.3 grains and work up carefully in 0.2 grain increments. I had done so in previous testing, but did not list the results here.

12.4 grains
Average velocity: 1160 fps

12.6 grains
Average velocity: 1170 fps

12.8 grains
Average velocity: 1185 fps

13.0 grains
Average velocity: 1200 fps

Notes.

Accurate no. 9 always seems to exhibit flattening primers. Yondering hypothesized that it might be due to the fact that some of the tiny kernels make their way down into the flash hole and into the primer cup and increase pressure a bit on the primer. I think there might be some truth to that. There was no perceivable difference in primer condition from beginning load to end.

The 13.0 grain load grouped excellently. 1" at 15 yards for 5 shots is pretty good for me.

No excessive pressure indications of any sort. I like the fact that 1200 fps is attainable with the 200 XTP by using data right out of a reloading manual.

Thanks Taterhead. A 200 grain XTP bullet traveling at 1200fps is no slouch and is apparently quite accurate.

Retest. All variables the same as above except 1) primer swap to CCI 300, and 2) abmient temperature.

I originally did workups with a CCI Mag primer. I wanted to do a re-test with standard primers. The velocities are slower, as expected. I attribute some of that to the fact that is was 20F lower for the second test. The Accurate no. 9 powder was from an older lot produced in Belgium that was noticeably temperature sensitive. The first two strings were 5 shot averages. The rest were 10 shot averages.

14.9 gr
Average velocity: 1257
ME: 543

15.2 gr
Average velocity: 1257 (chrony errors so limited sample)
ME: 543

15.5 gr
Average velocity: 1339
ME: 617

15.8 gr
Average velocity: 1366
ME: 642

16.0 gr
Average velocity: 1373
ME: 648

I bet that the mag primer was worth about 25 fps, and temperatures were attributable for the difference.

The brass looked far less "worked" with the standard primer. It would probably be about impossible to stuff enough powder in there to get excessive pressures.

Note: The more recent lots of A9 (made in USA) are denser, so potentially could add another several tenths. I bet 16.5 grains could get in there. Accurate reports that pressures at 15.9 grains is 32,700 fps.

Crap. Now there is another thing on the to-do list... I just happen to have some 155 XTPs onhand so might not be too long.

Good stuff. Here's an interesting observation I made recently, see if you have the same results: Within the 180-220gr range of bullet weights, Accurate #9 seems to give me close to the same velocity, for a given powder charge. For example, I'm loading my 220gr cast bullet over 13.0gr #9, for 1300 fps. The same load, but substituting a 180gr TC cast (Lee 175 TC mold), shot only slightly faster, at 1320 fps. I haven't found this to be true with other powders, but will be paying more attention now.

Edit: for anyone wondering, these velocities are from a 6.6" barrel in a G20 solid top long slide with a muzzle brake. The 220gr load is "full power", but the 180gr feels relatively mild.

Yes, I have observed the same thing, except maybe a bit more extreme. 180 XTPs actually are generally a few fps slower than 200 XTPs for a comparable charge - as much as 50 fps at the high end. I attribute that to the long bearing surface and high bullet pull of the 200 grainer allowing the slow-buring A9 to build up a head of steam. For whatever reason, 180 XTPs just don't run that fast in my G20, no matter the powder (800-X, Longshot, Blue Dot, A7, A9, etc.). A9 is tops at about 1230 fps with more room to go. That is followed closely by Blue Dot.
