MBC Glock Bullets?

[TheCracker]

So I finally got my glock 23 .40 cal few months ago. Got the dies, bulge buster, a 5 gallon bucket of free .40 brass (nice to have friends with connections!) and most importantly a storm lake barrel.

I've been shooting 180 grain fmj and carry 180 grain XTP factory loads in the factory barrel.

So my main question is which of the Missouri Bullets have any of you guys tried in your glock 40's. I'd like something with a similar POI as the XTP's with the factory barrel (that's what I will be carrying) if at all possible but I defiantly need to go with MBC's since the fmj's are so much higher.

Thanks for any input!

I have a storm lake barrel in my glock 20 so I can shoot 40. The IDP 7's Missouri sells work well. I've also shot ten thousand at least through my stock glock 22 and 23 barrels. Missouri bullets are good.
Lead is different and they don't shoot "the same". Lead is softer and lubed. It accelerates and goes faster with the same amount of powder. Too much pressure will cause "cutting" and any barrel will lead up.
You have to load the rounds with "lead" loads.

glock 23 ... storm lake barrel ... So my main question is which of the Missouri Bullets have any of you guys tried in your glock 40's. I'd like something with a similar POI as the XTP's with the factory barrel (that's what I will be carrying) if at all possible

These are MBC bullets I use for 40S&W and G22/G23/G27 with Lone Wolf barrels but I usually load with W231/HP-38 to produce lighter/less snappy recoil loads that are still accurate as I can adjust the level of recoil from light/soft to moderate.

While I do not usually recommend faster burn rate powder than W231/HP-38 for 40S&W (with the exception of Green Dot), if you are trying to duplicate factory level snappy recoil with lead bullets for range practice, consider using Red Dot/Promo. During Promo testing using Red Dot load data by weight (as indicated by Alliant), I found the test loads produced similar to factory level "snappy recoil" with 180 gr MBC TCFP bullet at 4.1-4.4 gr and shot to similar POA/POI as factory FMJ/JHP loads at 7/10/15 yards.

These are my range test results with Red Dot/Promo and G22/G27/LW with 180 gr MBC TCFP at 1.125" - http://www.thehighroad.org/showthread.php?p=6509911#post6509911

180 Lead/3.5 gr - Accuracy all over the 8x11 copy paper - Light recoil
180 Lead/3.8 gr - 7 yard 2" - 10 yard 3" - 15 yard 4" - Mild recoil
180 Lead/4.1 gr - 7 yard 1.5" - 10 yard 1" - 15 yard 4" - Moderate recoil
180 Lead/4.4 gr - 7 yard 1" - 10 yard 2" - 15 yard 2.5" - Firm recoil

The 180 gr Missouri Bullet/4.4 gr was also very accurate ... The 180 Missouri Bullet/4.1 gr load also shows promise as I kept getting 1" group at 10 yards.

If you are interested, I would suggest start charge of 3.8 gr and test 4.0 and 4.2 gr.

BTW, not sure how many rounds you have shot through your Glock 23 but if you shot over 3000-5000 rounds of full-power/factory ammunition, consider replacing the recoil spring assembly (RSA) as it will significantly reduce the felt recoil and muzzle flip.

I come across shooters that complain about snappy recoil of 40S&W. I ask if they ever replaced the recoil spring assembly in their Glocks and when they say no, I pull a new one out of my range bag and install in their pistol. They are pleasantly surprised their snappy recoil loads are now softer/milder recoiling. It's the same for 1911 recoil springs going softer than factory 16 lbs after several thousand rounds.

Current factory RSA for my Gen3 Glocks are 17 lbs and they can become 15/16 lb springs over time. I think Glock recommends RSA replacement at 2000-5000 rounds for the 40S&W models and 5000-7000 for 9mm when full power factory rounds are shot.

Thanks bds! Exactly what I'm looking for!

Actually I've only shot 40 hollow points and 200 factory fmj's. Too expensive for me to shoot factory all day!

Btw, I have a crap ton of universal clays. I do have some red dot also.

Anyone have experience with universal and lead loads? I see there is no published data so I would have to call and ask.

 

[Rule3]

How much does a "crap ton" equal? is it equivalent to a Boatload?

I use the IDP #5 but not in a Glock

You are lucky to have Universal on hand as looks like we won't get a resupply for a while.

I have shot Universal in 40S&W but mostly with jacketed/plated bullets and switched to W231/HP-38 for lead loads as I can reduce the charges and still produce accurate loads. Since you are looking to do the opposite of what most of us do with 40S&W (reducing snappy recoil) by replicating factory recoil with lead loads, this shouldn't be an issue for you using Universal at high+ range load data to produce accuracy.

Although there is no currently published load data for Universal and lead bullets, you could reference load data for Berry's plated bullets to conduct your powder work up - http://data.hodgdon.com/cartridge_load.asp

With 180 gr lead TCFP bullet at 1.125"-1.135" working OAL (Glock will feed 1.135") and Universal, you could start at 4.6 gr and test 4.8/5.0 gr to see how the recoil compares to factory loads.

180 gr Berry's plated FP Universal OAL 1.125" Start 4.6 gr (925 fps) 28,300 PSI - Max 5.1 gr (1002 fps) 33,100 PSI

I've shot the 155/175 SWC and 180 flat nose with excellent results using AA#5 and hp-38/w231. That was also in the stock barrel of my G22 with no problems whatsoever.
