Shooting in a new gun

I just purchased a new Ruger M77, 7mm-Rem. Mag. I was told to shoot in the Barrel. Never heard of this. Some advice would help.

Shooting in a new gun

Don't bother. It's a waste of time and cleaning supplies. It's a practice encouraged by the makers and gun care industry to keep products moving off the shelf. Trust me, breaking-in a new barrel does nothing for accuracy, longevity, or ease of cleaning. Just clean it before you first shoot it, and keep the barrel reasonably cool when shooting. In other words, allow at least a minute between shots for every three shot group, then let it rest for a few more minutes. If the barrel gets too hot to keep your hand on it then it's way too hot. Over heating a barrel causes more overall problems than anything else you'll do. Clean it after every range session and try not to put more than 20 rounds per session through your new rifle. Use a copper solvent after about every 75 to 100 rounds. Congrats on your new purchase. That's a great rifle and cartidge combo.

This could be a hotly debated subject. a lot of people absolutely believe in breaking in a new barrel and there are several methods of doing it. I've tried them all and I agree with Western Hunter, I've never noticed much difference in accuracy. People claim that a properly broken in barrel will also clean easier. Not that I've noticed.

Shooting in a new gun

i got the barrel in my .300 pretty darn hot about a week ago at the range( my scope was off and i was getting a little frustrated) so i was shooting my groups faster than i probably should have Brick Wall,) since then ive shot the rifle and have had extremely good accuracy 1/2 inch group on the bull at 200 yrds. should i be worried about my barrel or just dont do that again?

Agree with western. Don't worry with factory barrels. If there custom listin to the manufacture. Shoot em up.

Then too, after cleaning your barrel throughly, it's a good practice to shoot 2-3 rounds downrage off target before checking the accuracy of your loads. This fouls the bore and "settles it in". then do your test shooting. Some need this proceedure, some don't. I just do it with everything to be sure. Although, some may even take more than 2-3 rounds.
Once I have established what the inherent accuracy is of any particular firearm, I don't clean the bore again untill accuracy starts falling off. This varies between barrels, I have some barrels that needed cleaning after 50, then I got a few that will go 2-300 rounds. But those are select match grade barrels also.

Considering that you acheived 1/2 inch group at 200 yrds after things cooled down I'll say that you shouldn't have to worry about a thing. Sounds like you have a pretty accurate rifle. Just try to keep it cool from now on. Exsessive heat over time is what burns out barrels. Remember that the first (and hopefully the only) shot you fire in the field while hunting will be from a cold barrel. Therefore consentrate on making that first 3 shot group at the range from a cold barrel your zero mark.

That's excellent advice. I've found this to be the case in most rifles I've owned. Shooters worry so much about fouling (mainly copper) and accuracy that they rarely realise that some fouling is actually needed in a barrel for accuracy. I think it gets pounded into everyones head that copper jacket fouling is the arch enemy to barrels and accuracy, but it needs to be put into perspective. In extream cases of severe neglect, yes fouling is the enemy. I say don't worry about copper fouling until accuracy starts to noticeably deminish.

Pretty accurate! 1/2 inch at two hundred yards is incredibly accurate in my book (from a regular rig not an 18x sniper or varmint set up)!!! I'm happy when I get a half inch at 100 yards.

Damn good shooting congrats.

Western, I've been shooting my 22-250 and 243 pretty heavily over the last few months getting about 20 to 40 rounds thru each gun each session. I clean them after each range trip with regular solvent and after about 300 rounds I use an ammonia based copper cleanser.

You think that's too much?
