When I got my M70 300 RUM it was not very accurate. So I pillar bedded the action. This got me some improvement. After burning up a lot of ammo with no measureable improvement I cut 2" off the barrel and re-crowned. Now I get sub-moa with most any loads.
If I lost any velocity it is very little.
Just my .02 cents worth.

I glass bedded the action and first 2 inches of barrel and free floated the rest of the barrel. Groups tightened up and it now shoots to the same POI at any temperature.

Just bought it out of a pawn shop and i am trying to build it to be a 1000 yard rifle. I just dont now were to start. I've been looking for a new stock but i cant find anything on Boyds or stockys stocks. And i was taking to my gunsmith and he said to throw a muzzle break on it to take out the recoil. But i dont want to start working on it until I get a couple of opinions.

Bob I think I hear your asking how to improve the accuracy of your rifle that you haven't even shot yet. You may have a rifle that shoots just fine. Maybe the previous owner didn't like the recoil. Maybe you should go shoot this thing. Do a little loading for it and then if it won't group start looking for answers.

I had a muzzle brake on mine until I shot it elk hunting without ear protection. My ears rang for 2 days. As soon as I got back from that hunt I took the damned brake off.
If you can't shoot a 300RUM without a brake you have no business owning one, they really don't kick that bad if you have a decent pad on them. old Sorry to sound like Ray but I had a brake on that rifle and I will never have another.
Recoil is temporary, hearing loss is forever.

Muzzle brakes can be a cause of deflection by themselves. I tried one "custom" muzzle brake because I was ignorant to them and let the guy talk me into it. Never again.

Bedding and a target crown would be first on my list as well as a Jewell trigger if I was thinking 1000 yard anything. Accuracy Innovations makes a nice stock , not sure if they have one for your rifle but check them out.

Yes, a Knightforce is worth it.

Well, for factory loads, we've had good luck with the Remington greenbox with the 150gr Scirocco's. If you plan to shoot it alot, I've pick up some Fed215's, Nosler 180br Ballistic tips, and a case of WC872. That's where I would start.

When I bought the gun I bought a box of barns TSX 180 GR. I took it out to my friends range and shot about eight rounds of it at 200 yards and only made paper once. I can handle the recoil with no problem but the gun is really light and on matter how tight it is to my shoulder the barrel still jumps. So thats why I thought getting another stock and a muzzle brake put on it.

So you have no idea how it groups? The problem described could have been nothing more than a poorly adjusted scope. I'm not meaning to be offensive, but if you don't understand how to evaluate a rifle's accuracy potential, are you sure you are ready to take on 1000 yard target shooting?

Try shooting at 50 or 100 yards and get the groups on the paper, and have another shooter fire it too. Then evaluate the true accuracy of the rifle/load before you go spending a lot of $$$ on parts you may not even need.

No I dont take any offense to that. I have never shot a thousand yards before, and im not going to pretend I have. Thats why I bought this gun. The furthest I've shot 650 yards. And Im still learning. I have switched scopes already and I still have the same problem. So I think Im going to look into crowning and bedding the rifle. Oh and its a BDL.

I would still try some different load/bullet combinations before changing anything on the rifle. Also check to make sure the action is tight and check those scope mounts. If you have already checked the usual stuff and have a good quality scope on it and have experimented with different loads, then it is time to start tweaking the rifle. FWIW mine is a BDL with tupperware stock. It shot MOA or less with no prob right out of the box.

I've never had a 700 that didn't do better after GENTLY lapping the lugs. Put some black magic marker on the backside of the bolt lugs and chamber a fired piece of brass and check to see if both lugs have close to even contact. That will show you if lapping can help. Next is a Jewell trigger from Great Scott. I have seen a lot of Rems that shoot better with a little tip pressure than fully free floated. By all means try both. When you put a brake on it that will get you a crowning job too.

Lapping the lugs is jumping way ahead. I'd suggest you shoot some conventional bullets through and, as mentioned above, see what you got a 50-100 yards before making any big sweeping changes.
