Thanks for the feedback , guys I don't think its flinching as I've shot a 222 for a few years now and still do in 1" groups @ 100 yds, I'll take off the mod the morrow and try that, though what you said Baldie about the 1:10 twist, if so How do you have a min 100grn bullet then for deer as, thats my understanding of the law, I'm sorry but a little confused and no expert but if I go too purchase a 243 for deer, and have a 222, should I not expect the gunshop owner/salesstaff too make me aware of the limitations here or is it just me being slow.
