Re: Gunsmiths doing the 300 Tomahawk conversion

Well thanks for all the info!Yes the rifle is a 300 RUM now.What I really want to build is a serious longrange rig and I think the tomahawk is the way to go for me. The idea of buying the reamer occured to me Darryle,it seems that it would be the easiest way to go and I'd always have it for barrel changes. My problem is finding a competant gunsmith this side of the boarder that does this type of work.I was talking to one that suggested that I buy the 300 reamer and use a throater to go to the 338 since the case would be the same. Any comments on that? You guys seem to have this figured out pretty well.... your advice is welcomed.

Re: Gunsmiths doing the 300 Tomahawk conversion

Has anyone here had a 300 Ultra Mag rechambered to a 300 Tomahawk yet to quantify exactly what MV gain there is? After all this time you all (a few) have had them, I'm still not sure what the MV advantage is, is there much of one?


Just my 2 cents, but if you are even remotely considering the 338, I'd go with the 338 Lapua case, and if you're willing to buy a reamer, Dave Kiff at Pacific Tool and Gauge will set you up with one for $135.00 with exactly what you want, improved or otherwise. If you're going to spend the money, it's more bang for your buck for sure.

Call Ray Romain in Brockport, PA---814-265-1948.

He can set you up with the reamer and possibly do the work for you when you decide to get it done.

I think in your situation, the Tomahawk would work just fine for you.
The new lots of Remington Ultra mag brass that the fellows are getting as of late, are "VERY" good.
You won't have to have any bolt face work done, at an extra charge, since you already have the rifle chambered in the RUM configuration.

I believe the Tomahawk will do about anything any comparable cartridge case, that holds close to the same capacity (or even a tad bit more) will do, regardless of what it is.
Using a correct powder and bullet is the key.

Good luck
