First Post/Question: 300 RUM

I have a Model 700 300 RUM. I bought the gun new in 1999 and put a 4.5-14-50mm Leopold on it. It has a stainless barrel/synthetic stock. It is not the heavy barrel. I do not reload, I shoot the factory 150 grain Scirroco bullets from Remington. On a good day, I can get a group around 1.5 inches at 100 yards. I have probably shot around 400 rounds through it. Here is my question/scenario: I can kill a deer consistently to 350 yards(if he will stand still!) I want to have confidence out to 600yds and possibly beyond. What would you do? Thanks for your help. (I needed this website before I was married, when I had money!)

    Not an expert on the 300 RUM but one suggestion would be to take some of the recoil out of it with a muzzle brake. Another is to try different types of ammo. With the brake you could increase bullet size to a 180 or 200.

    First step would be to start hand loading. You might be able to get your groups down to 3/4" or less with a lod that your rifle likes. Next step would be replace the stock with a good pillar bedded stock. B&C makes some good ones for a reasonable price. Another thing would be to replace the trigger. Doing these things should help a lot and you can proceed one step at a time to see where each step gets you.

    Welcome to LRH and good shooting,

    +1 on the muzzlebrake. there's also other things you could do, bedding, trueing the action and barrel change.

    1. Your action needs a good home to live in. If the stock you have is one of the cheap factory tupperware stocks, replace it with a quality stock like an HS Precision or Bell & Carlson. If the stock you choose does not have an aluminum bedding block, then have the stock pillar bedded and have it skim coated.

    2. Recrown your barrel. This is one of the most overlooked accuracy enhancing tasks. The tip of many factory barrels are not square to the bore - resulting in poor accuracy.

    3. Have your trigger tuned to 2.5 or 3lbs. In the alternative, consider replacing the trigger with a good aftermarket trigger.

    4. Lap the lugs of your bolt. This will ensure 100% contact between your bolt lugs and the chamber.

    I've written these in the order in which I would do the work if I were to do each job individually. Although many gunsmiths will do all of this at one time. A good stock will cost you 200 to 300 dollars. The gunsmith work can be done for 250 to 275 depending on your smith.

    Lots of good advice there. Before you spend a lot of money on it bed the action and freefloat the barrel making sure there is no contact with the stock. I bought a used rifle just like yours this year in 338 ultramag. That is all I did and good handloads shot 4' groups at 750 yards. If that doesn't work you have great advice above.

    I think that getting hand loads for the rifle will give the biggest jump in accuracy. Everything else should come after that. JMHO. Where are you? Do you have a friend that can help you get started? For what it is worth, I have two buddies that have the same rifle as you, and they hold under moa without any mods to the rifle. Only good quality hand loads.
