I could not get any boattail bullet to shoot good in my 1/10 twist barrel.I bought some 95 grain SSTs with the flat base and groups went sub 1/2" when I seated the bullets to the lands.Years ago I used 85 grain Barnes BT X bullets in the 243 I had at the time.They were super accurate and I killed a pronghorn at 400+ yards with them and was impressed.
