22 cal jacket and core on left, 20 cal jacket and core on right
44 grain 20 cal on left, 53 grain 22 cal on right
Now the only challenge will be to see if my 12 twist barrel will stabilize the 44 grain pill. It shoots the Sierra 39 grain well so hopefully the 44 grain will do well too. Once I perfect a 22 jacket trim die or jig I will make some 32 grain pills or lighter. My 20-223 (aka. 20 Practical) shoots Hornady 32 grain Z-Max at 4200fps, I'm expecting about 3800fps from a 39 or 44 grain bullet.
The 20 cal jacket made from 22lr brass till had a bit of room in it at 44 grains. Probably get close to 50 grains but not much more.
My die has a 7s ogive and a .062 meplat. I think I could have got away with a smaller meplat, maybe .045 but I am very pleased with the results.
If it wasn't so blasted hot over here I might have got away for the weekend to try these little 44 grain pills out. We shall see. Next spring you can bet these little pills we see some battle on the ground squirrel fields! Should be very effective!
Good Shooting and Swage On!
