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.

Ok tomorrow will tell i will post my results or not.
These bullets were a bitch to load.They are extremely long. A#9 is a no go they list 11gn that was a completely compressed load.I couldn't even get the length of the bullet correct i had to go down to 10gn.
I loaded 800x, be86, #7, #9, all were loaded at book or just under their recommendations.
Hope i have fingers to type tomorrow.

The 10 mm master list is missing the Underwood 150gn Lehigh Xtreme Hunter solid copper
also the 100gn solid copper
also the 115gn solid copper xtreme Pen
sierra jhp 135 with power pistol 8/19
and 180gn Bonded JHP w/longshot
all underwood

Is there a button where you can click to get the newest posts by ascending dates

Well, my personal opinion is you need a purse.
Or maybe a wagon

im only looking for 1125 to 1150 both the gun and I shoot ok in the range mainly me.

I started off loading really hot rounds but after a certain point dead is dead and paper is thin

This fits with some of my be86 data for 180gn bullets

I would like to express my appreciation to the people who have done the 10 mm pull Downs. What a great resource. Sometimes when i've got nothing to do I go to that site and just look at the downloaded information.Again great job.

I just purchased a box of these bullets to reload. I went on their site and downloaded the load data. It is extremely anemic, probably loaded to 40 Cal. Specs under 1100 feet per second I would like to get these into the 1150 range. That is where my gun seems to Just love bullets. Has anybody experimented with these? And maybe give me some of your input.
I have loaded lehighs, one hundred and forty and one hundred and fifty gn in the fifteen hundred feet per second range in the past.
I have A #7, A #9, BE86, CFE PISTOL AND LONGSHOT.
I was thinking maybe hoping, that I could use 200 grain data, at least.
And yes, these do seem to be longer bullets.
