300 rum accuracy?

Hey everyone. A friend of mine has a new 300 rum. He says it does not shoot for squat. IMO I think he is flinching because the first time we took it to the range the scope nabbed him in the fore head.

I guess the question is. Can they be relatively accurate? I understand that such a tremendous case capacity does not assist in uniformity of pressure and also does not lend to accuracy.
 
yes they can be extremely accurate. jump on youtube. you'll see them being used for extremely long range shooting on very small targets. what rifle is it?
 
on top of flinching which would be hard to avoid on that calibre im sure, is the scope set up correctly or did he put it on himself possibly incorrectly and canted?

If the scope hits him in the head then there wasn't enough eye relief to begin with - you need 4 inches at least for a calibre like that and any decent gunstore or smith would have advised against a scope with too little eye relief had they been asked to put it on. Any idea?
 
Case capacity has little to do with accuracy. How the powder column burns has a lot to do with accuracy.

There is nothing to suggest that the 300 RUM is any less accurate from an internal ballistics perspective than any other magnum.

It was bought new. Maybe I will ask him if I can borrow it and work up a load for it. I think the rifle should shoot well. For testing I will put it on a lead sled. Not that I can not handle the recoil but working up a load will take some time and may leave me a little beat up.
 
Does he own any other rifles or did he decide to join the club with that .300 RUM?....

In any event, I will join everyone else and say that he is flinching and/or the scope is not mounted properly.
 
A .300 RUM would probably be easier to get best accuracy with than a belted magnum case with the same capacity. Belted cases have been notorious for accuracy problems since their popularity spiked in the 1930's. Best accuracy's typicaly attained with new cases or full length sized ones that reduce case body diameters all the way to the belt, not 1/32nd of an inch in front of it where a ridge appears when the case head's all the way against the bolt face at peak pressure and there's a bit of clearance between the belt and its headspace shoulder at the chamber's back end. That ridge on fired belted magnum cases causes inconsistant fit of the case in the chamber at that point.

Note a rifle team shooting the 7mm SAUM round set a new record at 1000 yards at this year's NRA Nationals. Good choice for cartridge as it' got less recoil than the 30 caliber ones making it easier to shoot accurate when fired off ones shoulder.
 
With hand loads I nibble around the 1/2 MOA. But my rifle weighs in at 20 lbs and has a muzzle brake for a reason...
As Remington produces 3 power levels in 300 RUM (basically 30-06, 300 WM and full bore), buy him a box of the level 1 stuff to get rid of the flinch.
 
An old timer showed me how to shoot a magnum rifle and never get nailed over the eye. No matter what the scope relief etc etc is.

You stick your chin out (tilting your head back) and slide your head forward or back to get the right sight picture. It's comfortable and you don't have to fear the scope.

Try it, you'll like it (as they used to say).....

I too have learned the same or at least close to it. The only scope to ever get me was a Stevens model 200 300 win may. Not off the bench. But when I pulled up to make a shot on this Buck I saw back in some pine trees. The rifle as it recoiled slipped right off my shoulder and nailed me.

Well I got the buck but got a black eye as well.
 
Mine shoots very good

I bought a new Rem 700, wood/blue with iron sights, when they first came out. Neither brass nor reloading information was available. I bought 4 or 5 boxes of factory Rem. loaded with 180gr. Nosler partion bullets. Now, I have never had much luck with partions where accuracy is involved. The scope is a 3-9 Conquest in QD leupold bases.
I have shot a lot off a bench with sand bags for the last 50 years. The recoil of this rifle is without exception the most difficult to control of any rifle I have. That includes a 416 Rem Mag. With a sand bag under the fore stock, and one under the butt stock I have to hold the fore stock with my left hand ahead of the front sand bag, exerting force on the rifle into my shoulder. This is a difficult hold while trying to slowly pull the trigger.

The first time out, with the stated factory ammunition I shot several 3 shot groups at 100 yards. The largest was near 1.5 inches. About half were under that and several around one inch. I shot through a chronograph at the same time and the average speed was real close to the advertised 3300fps. Mine were around 3280fps.

I finally got reloading information from Nosler and that was with RL 25 powder. I did work up loads at about the same speed and slightly smaller groups than the factory ammunition. But not by much.

Unless there is a problem with either the rifle or the scope I would put my guess towards shooter ability. Personally speaking the 300 RUM is a very difficult rifle to shoot well off of sandbags on a bench.
