question on a load out of a glock 35 factory barrel

I just switched to limited major recently and havent been able to get a hold of a chrono yet.

I'm shooting a Glock 35 with a factory barrel and 200gr BBI at 1.135 (varys a little but not much)

They only powders I got on hand is TiteGroup and W231 and HP38

My question is what are loads that ppl are using for this combo, I've did a lot of searching but havent really found what I'm looking for, also what other good powders are there out there for this. Apprecite it guys

I wouldn't try to reload .40 Major without a chrono ...

You're using heavy bullets and fast powders - lethal combination. They produce the least

amount of perceived recoil, so they're a great idea, but you are skating on the edge with

those loads - you REALLY NEED a chrono.

And, you need to make certain that you are NOT getting any bullet setback - push the bullet

against your reloading bench as hard as you can, and measure the OAL to see if it shortened.

If you have bullet setback, with a Major .40 load with a fast powder and heavy bullet, and you

might have a problem.

I've loaded some with 3.8gr of titegroups and havent noticed any pressure signs yet. Ive testested for setback but not in the way you mentioned. i mic'ed them then loaded them to mags then chambered them my pulling the slide all the way back and releasing it and didnt notice any setback when i remic'ed them. I could be going about it all the wrong way though. I've never loaded much 40 just always 9mm.

Any load details on a 180 BBI I'm not married to the 200's but i do like the less preceived recoil of the 200s

Buy 180gr bullets, buy a chronograph and keep your digits in tact. It's easier to shoot when you still have all of them.

Loading 200gr bullets to 1.135 with fast powder is playing with fire.

The major PF 200 grain loads for 40 S&W were originally, IIRC, all long loads at about 1.200" COAL. They run fine at that length in 1911/2011 pattern guns, albeit still at high pressure as shown by flattened primers.

Pressure will be WAY up loaded to 1.135", even 1.155" (around the max I think that most Glock mags will handle). My first year I loaded a 200 grain load to SAAMI spec 1.135" and promptly blew up a gun (a Taurus) on the fourth shot. The brass recovered on the first three shots all showed near blow outs near the case rim where the chamber did not fully support the case.

Older version Glocks in .40 are already notorious for bulging the base of even factory/commercial rounds (the Glock Bulge or "guppy bellied" brass). You shoot a load using a nonstandard recipe with a much shorter than recommended COAL and you will likely hurt yourself or the gun or both. Please go down to 180, or shoot the 200's in a gun that will take the longer COAL's.

Yall have me deciding to drop down to a 180. I'll use up my remaing 200s and load them light for practice ammo as to not push the envelope on pressure. I do like my fingers and hands. and yes my Glock likes the 1.15 oal it passes the pluck test much better than 1.135
