Re: Newbie help
If you can no longer seat your bullets out far enough to touch the lands in the rifling, your throat may be eroded....but, your particular rifle may have had a long throat to begin with.?
If your accuracy is no longer acceptable, your barrel my be getting worn out....but, that could also be due to a change in ammo lots or barrel fouling.?
A bore scope can tell the story....but they're expensive; often times, those who have borescopes are gunsmiths and some will attempt to sell you a new barrel when it's really not necessary.
Illinois humidity and lack of use.......rust may be a bigger concern than barrel wear.
I'd say as long as it's shooting to your satisfaction, don't worry about it. I put over 3000 rounds through a 25-06 barrel before it was shot out, and the majority of those bullets were 85 grn going ~3600'/sec.
To my knowledge, folks that are shooting the 6.5-284 are utilizing barrels at least 26" Heard tale of barrels 32" long needed to get all the goody that cartridge is capable of. It's supposedly got a reputation for wearing out barrels easily, but I can't say from personal experience.
I would buy a 6.5-284, but it would have a 26" tube, if not 28".
Best of Luck
