I installed a 20" Criterion hybrid .223 Wylde barrel, I broke it in today, initial velocity avg w/ BH mk262 was 2786fps. After 80rnds of m193 I chrono'd 10 more rounds of BH mk262 and the avg jumped to 2810fps. I was hoping to get 2850fps w/ mk262 out of this barrel.
Wondering what's the most velocity gain you've seen with a new barrel after (x) amount of rounds?
