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?

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.

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.

Not surprising with action moving in the stock and the bolt touching the stock. If it were me I'd start to question/check all the work you think was done and it's quality. Ditto w/Nesikachad-check everything. if your not comfortable or able to check then have a quality smith take a peek.

the rifle was built by the one person, who is meant to be a reputable gunsmith in new zealand. ill deffinatly check if the mag box is floating and maybe see if i can get something done about this bedding situation.

I was actually quite surprised when i relised that the bolt could touch the stock. the bolt doesnt touch on the sides it touches on the bottom just to explain that a little more.


if this is the quality of work Im starting to wonder if the chamber has been cut in line with the barrel and how square the threads have been cut...

hmmm.....

I would take off the scope with rings and check the scope mount screws for tightness.

I would take another accurate rifle to the range and shoot both to see if the whole problem is wind.

Need to find someone who knows how to build a rifle ---- you have a blacksmith not a gunsmith.

the mag box can wiggle around.

the mount is on tight and the rings were tight but they were never lapped so i just put some signature rings on to see if that changes anything. ive made room for the bolt to close without bottoming out on the stock.
I've been pretty busy with work and it seems its always the winds always blowing when i have a spare moment and calm when im busy. But ill get it out at first oppertunity.

if this fails ill get that recoil lug rebedded and if that fails ill put my tried and tested nightforce on it! if everything fails ill have to have it rechambered or reabarreled by someone else

hopefully it all works out!
