[QUOTE="rockchalk06, post: 3968195, member: 40794"] Working towards finding a starting COAL for these 230 grain Hornady A-Tips. Loaded to mag length with enough room to get reliable feeding, COAL is @3.750". These will not allow the bolt to close and after running a marker all over the bullet, I am 100% in the lands. Jam test was next. Seated them out to 3.900" and sent the bolt home. 3 times, I got 3.720.5", 3.720" and 3.720.5". Lets call that 3.720" to jam. Hornady is calling for 3.685" for a COAL on the 230 A-Tip. Using their data on their bullet, I'm only jumping .035" to jam. That seems shorter that I'm used to with Bergara barrels. I know in my .308 Premier, I had over .070" jump to jam and .060"ish in my 6.5 HMR from what Hornady or Berger was calling for. I'm going to run with 3.700" COAL and 2.817" off the O-Give. [/QUOTE]
