How accurate is my rifle

[LR1955]

I use "cold-bore" as a general term, as I don't really think barrel heat is the culprit in my particular case. I think the issue lies mostly with copper fouling, where as bonded bullets seem noticeably worse regarding first-shot fliers from a barrel left fouled with the same bullet (which pertains to hunting applications).

I shoot almost every day with few exceptions. I've shot my entire life, but for the last couple of years, I probably average at least 4 days per week shooting, almost exclusively 6.5 AR's (Grendel and Creedmoor), with some 5.56 and 7.62x39 mixed in once in a while. When it's not hunting season, I might make 3 range trips in a day (600-yard private range 3 miles from home). I've tested a lot a 6.5 bullets in various barrels (3 Saterns, 2 Sabre Defence, 1 Krieger, 1 BHW, and 1 Criterion), and stick to my belief that not all bullets behave the same with the very first "cold-bore" shot, regardless of which weapon a session begins with.

Drifter:

Roger.... Questions for you out of curiosity.

First, is the first shot within your call area?

Second, can you predict where the first shot will go well enough that you will adjust your sights before that first shot with confidence the shot will go to your good zero?

Thanks!
