.308-30XCB-2490fps-10 twist barrel.
Went out shooting yesterday with a new load for my factory 20" Rem700 .308 with a 1:10 twist barrel.
I shot these relatively fast and the barrel got pretty hot. I THINK that's where the two flyers came from.
Had a cold bore flyer as well. Pretty happy with the results other than the pesky flyers.
10 shots at 100 yards. Prone off a bipod and a rear sand bag out of the bed of my truck.
30 XCB bullet sized to .311" lubed with Lar's 2500+ with an overcoat of BLL.
40gr of RX15 for a MV of 2489fps
