George,I bet you'll enjoy it. I have an 8 twist 22-250 and it shoots 68-80's like a dream. I hope that you're planning on using it for paper, cause it ain't much for varmints! Heavy bullet selection for critters is difficult... everyone loves the 75 A-maxes for critters though, except me, I didn't have the luck with them that everyone else has. Keep us posted on what you decide. I've had mine for 3-4 years now and have shot various bullets with good results. What kinda throat are you looking at on the reamer?
I had the gun built to pop groundhogs past 500 yards.... I can hit them,

just can't kill'em

... Then I built the 243 AI

(works like a dream btw) and the 8 twist 22 has taken a back seat... Sam
