If I want to change the barrel on my Stag model 1 can I just switch it out or do I need to worry about crown ? I want to get rid of the 1:9 twist and go to 1:7. Thanks for any info. Stilleto

Thank you for replying to my barrel change question. I meant to ask what is barrel crown? I was very distracted and my wording was off. Stilleto That's the last point of contact between the barrel and the bullet. When the crown is true and square, the trapped gas from the fired case escapes from around the bullet evenly and uniform in 360 degrees as the bullet exits the barrel. With a damaged or non-true crown, the gas escapes slightly more/faster on one side or area around the bullet, which can adversely affect a bullets flight/performance. ETA: One reason NOT to clean a rifle barrel from the muzzle end is to avoid damaging the crown. A damage free crown is a MUST for optimum accuracy. |
Have you shot any heavier bullets with the 1/9? A couple of mine shoot 69gr fine, some 75gr fine. Haven't shot heavier with them or my 1/7 barrels. Some seem to shoot better than others, but I wouldn't necessarily write off a barrel unless it is warranted. It is your barrel and your decision though. 95% of my shooting is with my 1/9 barrels and lighter bullets, but that may change. Is good to have both if possible.
