40 Cal Open Load suggestions

Hi there Glockers,
I am in the process of making the big jump to an open Glock, in 40Cal. what my wonderful reloader husband would like to know is, what is the best load out there for building the best load while keeping a MPF, for IPSC/USPSA shooting?

We are building it on a 35,,,,if that helps with ANYTHING......

Thanks for any information that you may have to offer.

Have a good day,

JGG

On Brian Enos they asked for an Open load and got a bunch of people responding with Limited loads.

Titegroup and Clays are not good powders for working the comp.

A good powder to start with is 7 grains of IMR 7625, behind a 135 grain bullet.

Power Pistol is more common and works well too.

You want a medium to slow burning powder that produces high gas volume.

Use jacketed 135s and the slowest powder you can find.

I would get a 9x19 conversion barrel and use it. Shooting 40 in an Open gun is very expensive compared to 9x19.

Some people are skittish about shooting 9 mm Major because the loads are beyond maximum. Slow, slow burning powders are required. It is cheap.

I understand a lot of folks like Hodgdon's Longshot for competition.

After tweaking - We found the PERFECT .40 Open Load

For those of you that have been kind enough to help,, or for those that may be interested in loading for .40 Open,,,,we have finally come up with an absolutely perfect load for my G-35 open gun.
Montana Gold 180 gr. FP with 6.9gr of HS6 powder - a note on the powder charge - we were getting some wonky Chrono readings before our area match, and did not want to travel out to the match and find out that we were not making Major Power Factor for USPSA - so, we bumped it up from 6.7 to 6.9, and the guys at the match declared it to read at a high but very manageable 178 PF!

Isn't it rather insane to try to make major with a 9x19?
.40 sounds a lot more sane, and I can't see anything better than a .45, but that is me.
Why does open division drop the PF to 160?
Here are some of the 9x19 Major loads I have heard people recommend. Better be sure you have a fully-supported chamber and a gunsmith who knows what they are doing...

Here is what I show for 9x19 and Longshot. Notice that to get to Major, you are almost 1.0gn over MAX. This sort of thing breeds damaged guns and, maybe, damaged shooters.

.40 is so much more sane. Here, you can achieve major with max loads of common powders and not +P+++ loads. Longshot starts off well over major (too slow) for .40, however. Just stock up on Nosler 135gn JHPs.

SLower powders give wide vel swings when loaded below midrange. HS6 would fit in that catagory. If you only want 180s @ 950fps+, something like WSF runs great there. PowerPistol would be another good choice for running a comp.

Major 9 is easy if you pick the right (slow) powder and go with 124-135 gn bullets. Making major with 115s can be tricky.

Sorry to bring up a dead thread, but I'm currious how there can be such a large difference in bullet weights for .40 open Glocks. I ran an open G22 last year and really liked the set up. BUt then of course there's the snappy .40. I could be interested in a different bullet/powder set up. I'm just a weekend warrior, but I'd really like to understand the open Glock a little better.

Jerseyglockgirl is running 180 gr bullets and loves it, while Noylj posts a huge list of loading data for 135 gr bullets.

Does the comp work better with one bullet over the other?

.40 cal is not the best caliber for open. 9mm is the only logical choice for a Open Glock. You loose too many rds to the bigger .40 round when you shoot anything but a 9mm/.38 Super Comp type round.

Thanks for the reply, but that's not my question. I know everyone shoots those calibers and that's great for them. I'm old and slow and I just shoot for the fun of shooting USPSA with an open Glock 22 and I leave the brass on the range anyway.

I would like someone to school me on why there's such a disparity in opinions about the best bullet weight to operate the G22 w/comp. I get the part about slower burning powder producing more gas. That's a no brainner, but how does a heavier bullet produce less felt recoil and better gas expansion in an open gun? Newton's third law would seem to suggest a lighter bullet would create less felt recoil, but the common open gun wisdom appears to support the heavier bullet. How does that work? What's the logic between heavier vs lighter bullets in an open gun, as far as working the comp with less felt recoil?

Please don't regale me with how great 9s & .38 supers are, it's not in question. They're both great calibers.

IF you compared a heavier bullet against a lighter bullet at the same velocity the heavier bullet will produce a heavier recoil.

In most cases however shooters load heavier bullets at a lower velocity than lighter bullets which accounts for the lighter recoil.

Mass, Momentum... all that happy scientific stuff. DanaT can explain it, he loves that stuff... it gives me a headache.

You should go over to Brian Enos forums and ask that question.

A Heavier Bullet loaded to the same Power Factor will have less perceived recoil. For those not paying attention I said to the same Power Factor (this always gets people confused). The heavier bullet loaded to the same power factor has less energy. So it has less recoil.

BUT

I don't think that is your answer. In a open gun it's not about the bullet weight and speed (creating energy and muzzle flip). In a open gun it's about creating the right amount of gas to work the comp. You don't want a heavier bullet because you want more powder for more gas to work the gun. In 9mm/38SC people are using mid-weight bullets. 124gr for the most part. As with most things extremes tend to not work as well. So I would guess something in the 160gr would work better. But you may need to go with a lighter bullet to get enough gas to work your guns comp. Only testing would tell you the answer.

Thanks guys!

That does make sense.

I've asked this question on Brian Enos and didn't received a response. Jerseyglockgirl's thread has been the only search result I've found that even comes close to addressing what's going on in an open gun regarding bullet weights and recoil.


Again, thanks for the schoolin'!

Comps are a whole different animal.

If you use a light bullet you will get less muzzle flip and the dot/sight will be easier to track. If you use a lighter bullet it also means you can use more powder and that means more powder to make the comp work.

The big thing is dot tracking. If the dot moves too much on recoil, start playing with powders and bullet weights.

For an open 40 the textbook solution is 135 or 155 gn bullets and lots of slow powder.

Just dig up this old post - whereas I am in the same boat looking for the magic combination of bullet weight vs. slow burning powder.

Good reading - thanks guys!
