Tested 3 different batches of ammo.

Got ES of 43, 96, and 74.

A little better. I have another way to improve ES.

One problem is I dont know where I got .9 OAL is good in this chamber. It's way too long and gets stuck on the rifling with these bullets.

The chamber wants a .85 and maybe a little less. But when I tried to go shorter the bullet was too low and loose in the case.

These bullets wont work on these guns. Will have to use regular fmj's.
