[QUOTE="Wallie, post: 2976118, member: 107256"] Interesting… I'm very curious what do you get for barrel life on your 22 BRA barrels, Greg? Not sure how apples to apples barrel life comparisons can be… I run pretty hot temps, longer strings of fire, when things things get hot and heavy in prairie dog towns… But I can count on 3k rounds of sub quarter (usually low .2xx's) of barrel life without HbN coated and 4k to 4.5k of accurate barrel life with HbN coated projectiles. This is with 53g vmax going 3540fps over 29.6gr of CFE223 loaded on a progressive. I would think you run mostly heavier projectiles? And probably mostly single base stick powders? Both would count against you barrel life-wise vs my use I would imagine. [/QUOTE]
