I was reinspecting these casings again today under magnification, The *Star-Line* case as shot from my S&W 1006 the one that had the loose primer before shooting and leaked...upon closer inspection it shows a very faint "SMILE" line. It is posible I missed it originally (remember this was used brass and the primer pocket was loose). That casing was pretty well beat up just look at the head stamp!

The area of the "SMILE" is to the left side of the casing and isn't even visible in the picture. It is possible I ironed it flat when I sized it in the "Pass-Thru-Die".

But I really think it was produced when I fired it with the 9.4 grain charge of LongShot that copied SwampFox's 1240 fps loading...remember I have never seen a "SMILED" casing from my pistols. This may have been the start of the very first one.

I believe *Star-Line* cases are very soft brass as compared to others brands.

Added new data to above post

Thanks Nick, Thanks for the data, that 6" barrel really brings out the velocity numbers!
I was just reading about some reduced Blue Dot loads in rifles...

Brainstormed for a sec and wanted to try some Longshot with 155gr JHP's, the bullets are just basic Remington JHP's. Looking at the load data from Hodgdon and not seeing anything other than 180gr and 200gr data, I decided that based off their results, 11.5gr of Longshot would be a good place to start some new data.

I didn't get to shoot much, very short on time and only got to shoot 3 per barrel, but here it is nonetheless. Hope to get more data soon.

Stock Glock 20sf (11.5gr Longshot)
About 75 degrees out, and I'm roughly 1050ft above sea level if any of that means something to you! Loaded using 1x Starline brass, CCI LP primers and loaded to 1.26"

1416
1386
1416
1406 AVG

Same load in 6" KKM bbl
1544
error
1549
1547 AVG

Notes: brass had a little bulge using stock bbl but not severe, and the brass from the KKM bbl looked great. Recoil was moderate at best, a little more stout from 6" KKM bbl. I feel 12gr would be safe and that's what I plan on loading up next. All in all, seems pretty consistent so far.

Good data, SD.... I've ran up to 11.0gr LS under a 165gr GS and GD.... VERY hot load....

Thanks for the 155gr info SDGlock23, I have some 155gr XTP bullets lying around and I've been trying to figure out a load for them.

Here's my contribution to the thread, I'm using a factory Glock 20SF (stock 4.6" barrel), Hodgdon Longshot, CCI No. 300 LPP, new Starline brass, 1.264 OAL, and 180gr Precision Delta bullets. I didn't like that Hodgdon limits the 180gr loads at 34,600 psi, so I went a little above and beyond.

Under Hodgdon book max (9.5gr):
9.3gr Longshot gave 1205 fps avg.

9.5gr Longshot gave 1213 fps avg.


Over Hodgdon book max:

9.7gr Longshot gave 1247 fps avg.

9.8gr Longshot gave 1260 fps avg with an extreme spread of 6 fps. (I really liked this load, and I'll be loading more of these in the future.)

9.9gr Longshot also gave 1260 fps avg, but extreme spread was ~30 fps.

10.0gr Longshot gave 1262 fps avg. Recoil was not hard, instead felt like a warm .40S&W.

That's as high as I got for the last batch. I was really hoping to hit 1300 fps out of the stock barrel, but it seems that that goal might not be attainable with Longshot.

Almost forgot, the maximum case expansion in the stock barrel was .4335" with the 10.0gr loads. All the rest expanded near to the same size. No primer flattening occured, and no other pressure signs in the brass as far as I could see.

Hope that helps!

Good data Turo. The last time I chronographed 9.5gr Longshot w/180gr I averaged right at 1260 fps.

Here is today's numbers:

165gr Sierra JHP @ 1.260"
10.5gr Longshot w/ CCI LP
Stock G20sf

Average: 1,353 fps / 671 ft-lbs

Same setup but 10.7gr Longshot:

Average: 1,357 fps. 675 ft-lbs

Notes: brass looked good, a little bulge but nothing out of the ordinary. For some reason Hodgdon doesn't list any Longshot data for 165gr (or 135 & 155). I came up with the above numbers, it's not book data. The first shot of each string (10.5gr and 10.7gr) was high (near 1400 fps), the rest were quite consistent. Had it not been for the high starting shots, the average for both would have been in the 1340's.

180gr FMJ @ 1.260"
6gr TiteGroup w/ CCI LP
Stock G20sf

Average: 1080 fps / 446 ft-lbs

Notes: brass bulged more than the above listed Longshot loads, nothing serious however. Not a warm load by any means, but it makes for a good plinking load for when you want to go easy and save on powder.

Looked thru all 5 pages.....very good info, but nothing referencing my load/bullet.

Not new to reloading, just the 10mm.

Picked up 2K of Penn 180 gr lfp bullets. Have decided (initially) on using Longshot.

Does anyone have any loads or experience with this or other lead 180's?


Sorry to revive an old thread, but thought the "LongShot" thread would be the best place. Thanks, Tracy

9.2grs LS + 180gr bullet = magic

Do you have a chrony?
9.3 may get you a tad more velocity because you are using lead (less pressure) but I think that will be about all you can get unless you are willing to go well over published load data. longshot is a bit funny that way

Just for future knowledge, try some WSF powder next time, It wont net the high velocity LS does, but its about the best lead bullet powder I have found (actually freakshow10mm suggested it to me)

Thanks.

Yes I have a chrony, but it is very few and far between times that I get to use it.

I searched thru some members loads from a different forum and came up with 8.8 as a load. Pretty good "bang", and recoil feels comparable to Hornady 180XTP's and GA 165 JHP's. Brass has consistently been thrown in the 20' range......seems about avg from what I've read on several forums.

My Delta (bought used) came with a substantially greater mainspring than the #25 I run in my other 45's (all 1911's). I'm thinking it's close to a #30.....extremely hard to thumb cock by hand. I run a EGW flat bottom firing pin stop (no radius) in all my 1911's. I also use a Sprinco Recoil Reducing guide rod in all my guns (I keep all my 45's setup to run majority +P loads). This setup delays bbl unlocking and seems to reduce muzzle jump. Comes back hard into the palm of my hand, but muzzle stays down better making follow-up shots slightly faster.
