This is a video I made of the 140 grain and a the 150 grain Lehigh penetrator and Lehigh defender.

I shot through a 2x12 into 10 pounds of clay, and then I had an 8x6 as a backstop the bullets went 1 and 2 inches deep into the 8x6.

I need to try this with XTP and gold dots as a comparison.

Okay little update
I poured out all of the powder and burned it. replaced all of the powder and Reset the powder dropper. I ran a few dummy rounds. Install the new battery in the conograph reloaded a few test rounds, and they were all book value. Not sure what I did wrong the first time but they were hot.

How did you keep the line so straight if I tried to do that it would look like crap

Try putting a tiny bit of gun oil on a rag and rubbing them it'll make the black come out better.

I just dropped it down two 11.6 grains of AA9 still average 1300fps

Just recheck nosler and hornady nosler #9, 12.4 max and hornady 8, goes higher for max.
Just recheck powder charge twice 12.4 and 12.3.

I need some thought here. I just undid all of my one eighty grain ten millimeter with a a seven I just reset up ten millimeter 200gn grain with aa9 9 shots.
12.4 grains of AA9 should be in the 1100's with a 200 grain bullet. My average was 1350, no apparent bulging, no bad primers.
Definitely, had to hold on shot Great. What did I do wrong.

Quote from: The_Shadow on April 22 2025 02:56:02 PM MDTI haven't but that may be interesting to see if they would have less friction. I'd be concerned about rust if the liners are not of quality nonrusting or corrosive materials.

they're either made out of brass or stainless steel.
I have a g20 that I use around the property shooting range and I have tried a four pound stryker spring but that just wasn't enough.
I was cleaning the gun, it just seemed kinda sticky in there.
Who knows?

Has anyone here tried the metal channel liners for the firing pin? Just curious

 

I take my gun apart fairly often.
I have many channel liners and extra
Firing pins springs, etc.
Everywhere I read were BE 86, it's not good for heavy loads. I'm not seeing what there talking about. I think it's a hell of a good powder. And I think it could be taken even further with that load, but I'm where I wanna be. I'm starting to wonder if 2400 would fit.

I Tested 8.0 of BE86 av velocity 1136 right where i wanted to be do these primers look flatten

Well, I have been thinking, I think this 185 penetrator bullet solid copper was originally designed for the 400 legend. That's said Im thinking they adapted it to the ten millimeter because of the .400 size.

I think a better bullet for the 10 mm would be a 170 grain penetrator or defender. This bullet just seats too deep for any useful powder loads and pressure's.

I'm wondering how one would go about cutting the back end off one of these and testing a 170gn bullet.

Primers looked flatter on A #7. All the rest, no change.
Also one of the A #7 would not resize to fit the sizer ?

BE86 7.7gn   H 1114 L 1078 A 1096  SD 18
800X 7.8gn   H 1024 L 1011 A 1017  SD 7
A #7  9.3gn   H 1005 L 1005 A 1005  SD 0
A #9 10.0gn  H 921   L  858  A 889    SD 32

As far as accuracy 800X With BE86 very close second BE86 very good velocity  with room to load more
I only did 2 rounds each yes I know its not enough but thats what it is #9 is out not enough room for any more powder at 1.255 @ 10.0gn
Shadow if you would like to try send me an address I will send you some to test with.
