Help Please--I'm Stumped!

[thermaler]

I know this is a Savage forum but you guys are the smartest and most helpful of any forum I'm on, so I thought you could help me!

I just bought a new Ruger American in 270 and am still breaking her in--but I am having a heck of a time figuring out why I'm having this problem:

When I fired the rifle for the first time my shots were spraying all over the place--minute of dwarf star accuracy--but as the barrel got very hot everything tightened up significantly. Everything in the scope system is rock solid. I did some stock work and the barrel truly free-floats now, but today I experienced more or less the same thing--the first 4 "cool bore" shots--which I timed to keep the barrel cool--walked all over. Then I shot the last four barrel hot and they tightened up sub-MOA and were virtually dead-on my intended POA.

I've experienced this with AR's--but never with a bolt gun. I figure something someplace is swelling up as it gets hotter and somehow imparting better accuracy--but what?? I can't confidently take this gun hunting shooting this way.

My guess is your hot barrel is making for a hot chamber which in turn is turning up the pressure on your loads (which they seem to like) so they are shooting tighter. If you're doing handloads, try hotter loads for your cold shots and see what happens.

I have all the reload gear--but haven't quite got my shop set up yet after moving. I've shot a wide variety of factory stuff--could the pressure factor make that much of a difference? It seems to happen with all sizes and types of ammo I've tried.

Well, you know a hot barrel shoots well. Do the most obvious thing first and see how she reacts. Rifles are just like women, you know that. Some like it HOT! :)

Are you shooting the exact same way each time or is there a little flinch in the first four shots until you settle in? I bet your right handed as well? And how is the trigger? Tight? Im with foxx for the most part you may need to turn the loads up a bit or get the barrel fouled up so its tighter.

Im with foxx for the most part you may need to turn the loads up a bit or get the barrel fouled up so its tighter.I do concentrate on repeating the exact same rest positions--although the trigger is supposedly dialed down to 3 pounds I find that it's very stiff and the break happens abruptly--I'm guessing working on the trigger a bit might help. It truly feels like no other trigger I've ever pulled--but I'm not blaming it. Since I'm still breaking the barrel in I'm frequently cleaning it--and someone made the suggestion that maybe this rifle just shoots better dirty--I don't know--but I'll skip cleaning before the next range outing. Thanks for the suggestions.

It might be clean bore issue not cold bore if you are cleaning it constantly

Had this happen with a single shot in 308. Almost a good buckshot pattern with 150gr bullets. Changed to 180's and the gun settled in to acceptable hunting accuracy.

hole crap 3lbs....I can also guarantee thats a big part of it and yes stop cleaning the barrel most barrels shoot better fouled and if its for hunting and you go out and zero your scope then go home and clean it you can pretty much bet your going to miss a buck or 2 until the barrel fouls again....when your groups open up then clean but dont take all the copper out just the heavy stuff...when your pulling light blue its good.

I know when I clean the barrel on my savage it shoots like crap on a clean bore. After 10 shots I bet it really starts to tighten up. It'll go from 1- 1.5" groups to 1/4-1/2" groups. And if I leave it dirty it'll shoot those tiny groups right off the bat next trip to the range. I generally leave the barrel fouled but when it does get cleaned I've gotta dirty it up to shoot right. The clean barrel changes my point of impact an awful lot also in addition to larger grouping. I'm no expert but I agree it may be a possibility.

[foxx]

Yeah I would not be surprised if it takes five or more to foul it good. Most savages do that for sure. Most aftermarket lapped barrels need 1 or 2.

[sixonetonoffun]

I'd try some 150gr bullets too. Friends wife and daughter shoot 270 and it really tightened up with the heavier bullets. 130's scattered pretty bad could never be confident it was zeroed. He doesn't reload so its just been off the shelf cor-lokts.

Once my groups open up on my rifles, I clean the barrels. I don't go overboard on cleaning, just of times of Hoppes 9 is good enough. Groups tighten up again.

[Digduggy]

I have always needed 5 fowlers and it settles right down, my cbi and savage barrels alike...

I clean every 100 or so to keep it consistent, personally...

[foxx]

But still, I will be surprised if you can find a cold bore load that shoots well in a sporter barrel after it heats up. It mKes sense the barrel should be fouled. It makes sense it should be cold. If it shoots that well with a hot barrel I want to see what it does after a long rest (let it get cold again) without cleaning. It will either be unbelievably good or way off. I simply have never known a sporter barrel to get better and have the same poi as a cold bore. Remember its the cold shot that counts when hunting.

Keep it dirty. Dont clean aggressively or thoroughly when you do and try some hotter loads to see if your barrel prefers high pressure loads.

[Digduggy]

Over 8 rounds is it really getting THAT hot?

On my -06 i would have to shoot over 15 rounds in close succession to start pulling up and left...

[foxx]

They are all different I spouse but my A-bolt 06 will wAlk right off the paper with each shot after a couple.

[Digduggy]

Oh ok, that is good to know... I dont have any sporters at this point, but I may get a light weight in the future when im done with my second heavy

The trigger is one of the features that totally baffle me. It has received very high ratings and praises in just about every review I've read--I think it sucks eggs bigtime. Right now there are no after-market alternatives so I'm thinking I'm going to have to take it apart and see what I can do to improve the pull and break characteristics.
