Good info 454, I built a 243lbc this spring, also with a 22" barrel, 1-8 twist. It's quickly becoming my favorite. I'm mainly loading 55 gr varmageddons right now as I have a bunch of them. 31.6 gr of 8208 seems mild and runs 3450. I've had them close to 3600 but want max brass and barrel life. I am going to work on some loads with a2495, I'm up to 30.7, just shooting and looking for pressure signs, no crony or accuracy data yet. I also will be working on a load with 85 gr sierra bthp as I have a bunch of them and will use them for bigger game and longer ranges. Early data with them had them at 3020 fps using 29 gr of 8208 and bughole groups.
No chance to work with bigger bullets but I've read that the 95 gr smk is ideal, with a .480 bc and speeds over 2900 fps.
