barrel weight and accuracy problems

I have a 6x47 lapua on a rem700 SA. the action has been trued and its sitting in a macmillan A5. it has a 30" lilja #8 contour and the barrel is completely free floating.

just wondering if the weight of the barrel on that action could be causing accuracy problems?

cant get the rifle to shoot that well, just wondering if i cut the barrel back to 26" would it make the world of difference?

No expert here, but I would think if the recoil lug is properly bedded, it shouldn't be a problem?

Re: barrel weight and accuracy problems

There are a great many Palma rifles built on 30" tubes fitted to Remingtons that raise all kinds of hell with the X ring at 1000 yards.

You have a cartridge capable of tremendous accuracy so you can eliminate that assuming your hand load procedure is solid.

There are a number of things that can cause elevation, flyers, and those annoying random "orphan" shots that don't want to mingle with the rest of the holes.

Start looking for a binding guard screw, a bolt handle touching, poor fitting bolt shroud, loose sights/scope, bad sights/scope, a cracked stock, a loose pillar, a bad/dinged crown, a worn out striker spring, crap bedding job, poor action machine work, and last but not least (drum roll please. . .) IS the barrel screwed on tight?

good luck!

I wouldn't cut the barrel, I don't think your barrel weight on the action is the issue. When you say "it doesn't shoot that well" That's pretty subjective. Can you elaborate ie-are you having the occassional flyer? Is it not grouping? A little more info would be helpful.

Re: barrel weight and accuracy problems

okay accuracy wise. i would call 3 out of 5 shots into a half inch at 100yards a very good load. ive used 3 different bullets of different weights and different styles with 3 different powders and it wont shoot.


actually i just noticed the bolt handle touches the stock when its closed. might have to deal to that!

the stock was orignally for a remington model 7. but it has been modified. the action can move forward in the stock but with the bolts done up i cant get it to move at all, im assuming the recoil lug is hard against the bedding when its done up tight. a professional did the bedding job and to me it looks good but maybe the bolt hitting the stock is the problem.

as i said the bolt was trued and all the guts ( firepin, bolt shroud, spring ect) was replaced with a speedlock system

I'm no expert either, but that sounds like your problem.

Hate to be the one to say this, but professionals don't allow bolt handles to touch stocks. You'd be wise to check EVERYTHING.

One other thing to check, is the magazine box able to wiggle up and down? If it's bound up it means that bedding job isn't doing anything as the action isn't in the stock, it's sitting on top of the mag box. You should have about .030-.050 of wiggle room.

Good luck.
