.308 Survivor, NEED HELP.
« on: February 16, 2009, 06:04:18 AM »
Without boring anyone with all the details, please note that several months ago I purchased a new .308 Survivor with a synthetic stock. Wasn't shooting well, so you guys helped me with info on a trigger job. Figured that lightening up the pull to 4 lbs +/-, might help accuracy at the bench. Have tried several different loads, different powders and a couple of different 3-9x scopes, (taken off of other rifles which shoot 1" @ 100 yds), and still accuracy problems. Starts out cold, ambient in upstate NY now is 28 - 32 deg F in mid afternoon, and the thing shoots right on, couple of rounds later and 4" spread. Left, right, high, low, its all over. Tried bases, rings, removing the forend stock, even bought factory Rem 150 Core- Lokts, to see if it is my stuff. Same brass, weigh out all my powder individually, same primers.............! This is frustrating. Clean the gun religiously, nothing seems to help. Thought that thermal expansion could be deflecting the barrel due to growth against the forend. Has tons, 1/16" of clearance around the barrel, except at the radiused portion engaging the receiver, and at the thumb screw lug which holds it in place. Enough said, I think you get the picture. Appreciate any suggestions, solutions, or any of that gray beard experience out there.

clean it less often and be sure the latch is dry, no oil, grease, or other lubricant or preservative, then shoot for effect....<><....:)

I'd be inclined to think it's got a rough spot in the bore that's accumulating copper fouling causing accuracy to deteriorate, I'd polish the bore good with the break-in techniques in the FAQs and head to the range again. Heat shouldn't affect the bull barrel of the Survivor after just a few rounds. If that doesn't help, contact H&R and make arrangements to send it back, the barrel may need to be replaced. Their standard of accuracy is 2" 3-shot groups or better with factory ammo. ;)

I notice you said a .308 survivor.  The first thing that comes to my mind is recoil.  W/O a pad on the back of that light stock, that puppy packs a wollop.  I'm for sure not trying to be insulting, but are you developing a flinch after a couple shots?  I know mine was so uncomfortable to shoot, I traded stock sets for one w/ a recoil pad.  Again, not trying to be insulting.

Thank you all. Recoil flinch I do not believe is a problem. I shoot a 444 Marlin weekly, and shoot 1" +/- groups with a 300 grain Hornady xtphp. That is a lot more kick than the 308. With all the coats I wear in the winter, felt recoil is minimal. I do appreciate the suggestion though, something I had not thought of. Cleaning the bore is usually done after a day or hour at the range, usually after a minimum of 20 rounds or so. Sometimes during the day if I am shooting 50 to 60 rounds in one session. I'm very fortunate, in that I get to the range 3 to 4 times a week. I have nioticed though heavy copper discoloration of the lands which project into the barrel, whenever I clean the rifle. Perhaps it is copper fouling. The gun shot much better when it was right out of the box. Accumulation of deposited copper residue may be the culprit. I will also check out the barrel break in postings to become more intelligent in that area. Again, I thank you for sharing your knowledge.

Steve,
I'd try a good copper solvent or one of the foaming bore cleaners that remove copper then
I'd do like Tim suggested in the FAQ's with barrel break in. Keep us posted.

try lapping w/ JB's and Kroil.  Good project for while you watch a shoot em up :D

I usually use a mixture of several different solvents when cleaning the bores of my rifles...

First Kroil, soak a patch and run it through. Let it sit for about 10 mins.
Follow up by dipping your brush in Hoppe's copper solvent.  Brush about 5 times w/ a Hoppe's soaked brush.
Dip a patch in kroil again.  Run 1 patch down w/ kroil. Follow up w/ clean patches until the blue/black stains get minimal.  Next use a little dab of Sweets 762.  Let that sit for about 10 mins.  Run clean patchs through again.  The ammonia in the Sweets will turn the copper blue.  Clean Patch until the blue is gone.  Follow up w/ an oiled patch. Run 1 clean patch out of the bbl to get the excess.

When cleaning heavy copper fouling, usually takes me about an hour + per bbl.
