.40 minor load - velocity estimate?

[C.W.]

I'm loading 180g B.B.I. (coated lead) with 2.8g of Clays at 1.120 OAL, through a Glock 35.

I've got a cheap Chrono and I clocked these before a long time ago and I thought they were plenty good, but I can't find that data. The S.O. questioned my P.F. yesterday, I guess we're going to have a chrono stage next match, don't know if I'll be able to chrono more rounds before then.

Anyway - do you think I'm good to go?

No. Assuming you are using regular straight CLAYS.

The load you list is below Hodgdons starting load of 3.0 grains.

A 2.8 grain load is way to close to sub-minor velocity IMO.

Their site can help. http://data.hodgdon.com/main_menu.asp

My G35 will flat not run with a load that light. My minor .40 S&W

load with Clays was 3.4 grains. Great load.

I really thought I was good - remember I'm talking lead bullets here.(does hoDgdons list data for lead bullets?)

My XDM 40 production load is a 185 Precision or 180 BBI with 3.0 of clays at 812 fps. Thats about 148 pf. 2.8 should be fine. And mine DO feel sub-minor!

[salilus]

Yeah you are probably good. You only need 694fps. I would speculate somewhere around the 730's. Either way, try running 3.0. You wont be able to feel the difference plus that was as low as I could go to get the accuracy that I wanted.

[C.W.]

Thanks, I'll try some at three. These shoot pretty accurate though - but more never hurts I guess.

Why did they question your Pf?

[C.W.]

It was just a comment after a stage. It went something like "I didn't see much muzzle flip, are you sure your power factor is O.K?"

I had JUST finished shooting so I was still kind of hyped up so I said something like "yeah, I think they're a hundred over or so."

Probably planted some seeds of doubt there, question caught me by surprise.

I used to run across shooters that would say things like that,..

I worked with my hands and arms all week long so my wrists and hand strength was pretty good,.. got called on not shooting Major out of a 5" .45 a few times, their reason,..didn't "flip enough"... so I usually replied " get the chrono out ,...and $20.00 "

paid for a few matches that way...

there are so many variables muzzle flip really has nothing to do with if it is shooting hard or not...

1. its a glock

2. its a .40.shooting minor

3. a good solid grip and reasonable arm strength and it comes straight back ,

4. steel is calibrated isn't it ? ?

or 20 years ago...a 1911 with weighted grips and properly sprung along with a fundamentally solid grip .... not much flip.

Good points John. Also the stage was shot prone through a port so I had extra support (more solid base).

My wife used to shoot 2.6gr of Clays behind a 180gr bare lead bullet with an OAL of 1.125" and this combination made Minor out of her M&P40. Granted that it was right at 125 to 126PF but it made Minor nonetheless. I would bump up her load to 2.8gr before any Level II match just to ensure that she wouldn't end up sub-minor and not once did she chrono less than 129PF.

I don't think that the moly coating that the BBI bullets get strengthens the lead at all so I would expect that load to make PF out of your G35.

One thing that I discovered is that with Clays, the faster you push lead, the dirtier the barrel gets.

[Mark R]

I run similar loads...For what it's worth.

Glock 35

2.6 gr of Clays

180 gr lead

1.125 OAL

12 pound recoil spring

lone wolf barrel.

131 pf.

Glock 22

2.6 gr clays

180 gr lead

1.120 OAL

12# recoil spring

LW barrel

132 Pf...

Std Dev of 5.

With 185 moly in G22, I use 2.5 gr clays for PF 131.

With 185 moly in G35, I use 2.5 gr clays for PF 134.

I have a 40 minor load for my 610 that one person made a comment about.. there is very little muzzle rise or perceived recoil.. and his comment was, "That's not fair!".. well.. it makes minor.. why isn't it fair?
