new gun break in

what do yall think is the proper way to break in my new 25-06? ive heard everything from one shot/clean to 20 shots/clean.there seems to be no clear rule or preference.how important this is has never been explained to me.my 30-06 doesnt hold a tight pattern at 100 yds-could this be the effect of a bad break in? or does anyone else have this problem with a winchester featherweight? the pattern will be real tight if i let the barrel cool down between shots-not real practical in the field. thanks for the input. billybob

new gun break in

When I got my .300 win mag last year, I looked at all different kinds of theories and talked to all kinds of people about breaking it in. What I ended up with is kind of a mix of all those things.

Basically what I did was for the first 10 rounds I put through it, I shot one round and cleaned it - all the way down to getting all the copper out each time. Yeah it's time consuming, but it helps get any and all machining imperfections out of the barrell. After that, I would shot 3 rounds and then clean it - did this for 10 cycles (3 shots X 10). At that point, I felt pretty confident that my barrell was pretty well broken in.

Lastly, if I were you, I would invest in two things:

1.) A bore snake - It works wonders for cleaning time

2.) Cheap ammo - You don't need premium stuff yet and, furthermore, you don't need to worry about accuracy at this point. But something on the lower end and once you get you barrell broken in, then start worrying about accuracy and what rounds it likes to eat. When I started breaking in mine, I was shooting well outside of 2.5" groups @ 100 yds. When all was said and done, I brought it in to 3/4" groups @ 100 yds.

Good luck, have fun, but mostly, be patient - it's gonna take some time, but you'll be pleased with the results.

p.s. - I don't know exactly how temperature affects accuracy, but be careful not to shoot if your barrell is too hot. If you do shoot and your barrell is too hot, you could warp it and damage it permanently.

There is no specific way to tell you how to make a barrel shoot better. Some barrels throw spitzers better. Some throw boattails better, etc... One thing that I have noticed is alloyed copper jackets leave less fouling than copper jackets, but that may or may not have anything to do with accuracy.

These target shooters around here spend months and months of their time looking for the ideal combination. Some barrels shoot better after a good cleaning and I've seen barrels that need as many as 5 or more fouling shot before they can bring them in.

If the rifle is going to be used for hunting only and your getting an inch to an inch and a half at 100 yds. that's a decent accuracy. If you want to try and tighten up the groups try a few different types of bullets. Make sure that the bullet you pick is the proper bullet for the game your chasing. If your a reloader pick a bullet that is designed for the game your chasing and try an assortment of different powders with varying load weights. Either way there's going to time spent at the range.

If the rifle has a light hunting to sporter weight barrel it probably isn't a good idea to put more rounds through it than the magazines will hold before cooling the barrel. If you don't have the patients to set and let it cool take two or three more guns with you to shoot while it's cooling.

Good luck

the procedure therookie described will work just fine used a very similar method myself. I will add a couple things on cleaning. I used USP bore paste, and kroil oil. I will take a bristle brush one caliber smaller than my gun and take a cleaning patch and wrap in around the the brush. then put oil on it for the swab, and do the same with the bore paste. If you read the direction on the bore paste it will say the same thing. this is what I use on my new gun only. trying to take better care of this one.

new gun break in

I picked up my new rifle from the gunsmith yesterday. Out of curiosity I asked him and another gunsmith friend about break-in on this new barrel. The response from the smith, that made the rifle, was to shoot a magazine load of rounds through it, clean the barrel and shoot another magazine load through it and it's broke in. The other said to put 5 rounds through it, clean it and shoot another 5 rounds and it's broke in.

They both suggested that after the break-in period use a copper remover and if I wanted, a bore paste.

They both also specified that barrels don't wear out. They rust out. Tiny little spots of rust not visible to the eye form inside the barrel and deteriorate the bore.

Plain and simple. If I clean the bore after use and give it a light coat of oil afterward there is no reason I won't be able to put several thousand rounds through it. The old timer was telling me that there are guns out there that he has built, he knows have more than 5000 rounds put through them and they still shoot accurately. Not long range competition accurate but under 3/4". Still more than good enough for hunting.

On your Winchester featherweight check to see if the barrel is touching the stock after it heats up.
Barrels have memory when they cool down.

fuzzybear I believe you are referring to a floating barrel, If you can slide a dollar bill between the barrel and stock. before it's hot.

too be practical bob if you are shooting that many shots at an animal maybe you shouldn't be shooting at it in the first place. Apparently you can't hit it, or are not a very good shot in the first place. I suggest you spend more time shooting at longer ranges to see what you are capable of hitting.

thanks to yall for the input. o.k. sagebrush-im not talking 3 shots at a deer in the field.if i cant make a clean kill in one shot i dont take it,as i hope you also do.at the range though i think we all strive for the tightest groups we can get.then in the field we get the one shot kill.

Billybob; I must have read your original post wrong. It's when you said (not real practical in the field.) It came across to me as one of those few people you have to empty their gun, before they realize that they have missed. and have no clue where/or what they are shooting at.
