Here's the load that worked in my triple duece. 24g of BLC2 powder behind a 50g speer TNT hollow point. I used CCI small rifle primers and WW cases. 24g is a starting load up to 26g max. This s/b about 3000 ft per sec. It was a really accurate load in a BSA heavey barrel. Load the bullets out as far as you can and still clear your mag. I chose BLC2 for its metering and with standing cold temperatures. The TNT bullet worked well on coyotes with little damage to pelts.
I think you will find the 222 easy to load for accuracy. They are one of the best accurate cartridges in my opinion-----Cowboy
