300 R.U.M., with a 30\" Barrel?

Hello all.

I am building a new rifle up. It is going to be a 300 Remington Ultra Magnum on a Model 700 receiver. I plan on using 200 - 220 grain SMK's, and or 200 grain Accubonds.

Initially I will use a 30" Lilja Barrel.

I have a few questions?

Is there "that" much advantage to be gained in a 30" barrel, over a 28", or even a 26" barrel? I want to punch both paper and flesh out to about 1200 yards.

Will accuracy suffer with the longer barel? Can I expect the same level of accuracy in the longer tube, that I have grown to expect in a shorter tube?

It is a #7 contour Lilja.

If I find that it is not worth it, I can always have it cut back until I am happy.

Also is there any recommended "pet" long range loads for this 30", 300 RUM? If so, what kind of velocity can I estimate?

Thanks in advance.

Bill Bailey on here shoots a 30" lilja tubed 300 rum. He has had great luck with the 240gr SMK and is trying to work up a load for the 210gr WildCat ULD RBBT bullet now.

you didnt state your twist so I will guess that it is a 1-10 so you can shoot the 240gr bullet even though it calls for a 1-9 twist.

He thumped a buck with this bullet last deer season and it laid to rest any concerns I had about a SMK preforming on big game!!!

Here is the exit wound after the bullet trveled from the front shouler to the opposite side hip.


I would tell you to try and get the bbl in a somewhat lighter bbl, so it is easier to carry. And shoot the 200-220gr bullets. I like the 210 wildcat and the 200gr accubond.


good luck
steve

Here is a video of Boyd Heaton's 300 RUM and I am sure it has at least a 30 inch barrel if not more.

210 JLKs

Lerch, it has 1-10" twist, sorry.

It should do OK with 200, 210, or even 220 grs.

I am very familiar with the 300 WM. Most 300 WM's that I have owned and shot... liked 180 - 220 gr pills. Unfortunately, at 240 gr they started losing some stability.

However, given the velocity of the RUM, I don't know about a 240 gr pill at over 3000 FPS.

Thanks buffalobob for the vids. I can't wait! My longest deer to date was with a 300 WM, 200 gr SMKs, at 965 yards down in south Georgia.

Re: 300 R.U.M., with a 30\" Barrel?

Im not an expert here. I would say that you can add about 50 fps to whatever your reloading manual says avout velocity. I saw somewhere that optimal barrel length is supposed to be about 27.5-28". I would be fine with 30", the only concern you might have is about hanging the 30 heavy barrel off the receiver. There was a threat just recently about this, check the past threads. I dont think you will lose any speed with a 30" barrel and accuracy should be fine also. As for loads, you might want to try rl powders. http://www.accuratereloading.com/300rum.html

Get one, I love mine!!! Don't shoot anything less than 200 gr or your wasting your time. Personally, I would look @ the Berger 210 or the Wildcat 210 or possibly the JLK 210. All will have very high BCs and will fully stabalize in your 10" twist. I've had issues w/the 240s destabilizing as they go subsonic.
