Of the two I go with the 300 RUM. But if I personally was going to build a new rifle I would have to be different and do a 358 STA or 358 UMT, just because I like the 35 caliber and because I can. My other choses would be some sort of 270 or 338.
Both have poor barrel life. If was going with the rum with the longer mag, I'd go 338 edge. It will give you everything thing those two will, but have better barrel life.
I currently own a 28 Nosler and shoot my buddy's 300 RUM on a regular basis. I think you can't go wrong with either as far as ballistics or terminal performance. The 28 is easier to load longer bullets for if you have it throated for 195's. The RUM will always be handicapped with the bullet seated deep in the case. With that said, of the 2 cartridges you listed, I would go with the 300 RUM. The barrel on my 28 is toast at around 500 rounds down it.
If you are open to other options, have you looked at the 30-28? That is what I am going to rebarrel my 28 to. You can seat the longer bullets out where they belong and it looks like a hammer.
These days I'm more and more dependent on the RUM. I live with three women. Sorry, had to throw that out there.The Rum will never let you down
300 RUM.Ok I have been debating for months on what long range rifle I want to build. I'm going to build off a doner Remington 700 action. I have narrowed it down to two calibers. The 28 nolser or a 300 ultra.
I was thinking of the 28 nolser throated out to receive the 195 bergers to get the high B.C. of the caliber
With the 300 ultra I would get an extended mag and make sure its throated to seat the 225 bergers out further.
I've hunted with a 300 ultra since I was 16. So I dont know if it's just a confidence thing that I keep wanting to go back to that caliber. I know the 29 nolser would have a little better bc
Gaaaaaaaa I dont know. Help me choose!
If you are really set for long range capabilities have you already rejected the likes of .338s: Norma, Lapua and RUM? There are bullets of phenomenal BCs - the VLDs, etc. There has been tremendous advancements in the .338s the least of which is not the military applications and the funding for R+D. // If interested in keeping the chambering in the 7mm/.280 area . . . my favorite for personal interests is the .280 Improved OR better yet getting into the area of 7mm/280 . . . WSM and RSAM. (JMO) No help from me on your specific original question though . . . sorry!Ok I have been debating for months on what long range rifle I want to build.
