Re: 300 norma or 338 edge custom rifle build

I just recently finished my LR build. I was seriously considering a .338 of some kind. Most likely would have been the edge. But then I started looking at long range ballistics between a fast 300 using 230 Bergers compared to a slower .338 pushing 300 grain Sierras and OTM's. I was able to design and have a rifle built (full custom 300 RUM CMT) that easily pushes the 230 Berger Target at 3250fps with no pressure. It prints well inside .5 MOA. When compared to a .338 cal 300 grain Sierra at 2850fps, I walk all over it even past 1500 yards. Several hundred fps more speed and a couple hundred more ft/lbs energy past 1500 yards. Now with the .338 300 grain OTM (2850fps) I'm neck and neck on energy but surpass it by about 150fps on speed again all the way to 1500 yards. I was really looking hard at impact velocity and getting the bullet to open better at really long distance. Now if you step up to a faster .338 then that's a whole new ball game.

The 300 norma imp. Really has my attention running 230gr pills. I've been researching it and there seems to be some controversy over going to the 40 degree shoulder, some are saying only go to 35 max. Any experience with this gentlemen, looking for solid data as to whether or not there are any issues. How much more oomph does the imp have on the standard. My build will be sporting a 28-30in barrel.

Ive explored this option too and i just dont see a great advantage in this. Most of the taper is already blown out and u will gain 150-200fps at the moost from what ive read. Fireforming the cases is more work than its worth if u ask me. Itll cut your barrel life back from an already relatively short life to begin with!

But thats only my opinion.

Ill ask my budy that just built the 300 FOG off 338 Norma.They built 2 and are just in beginnig test stage. He has a 338 LAI and competes in 1000 Bench and wins. He has a ton of experience in getting stuff to shoot long. I have a pict of cartridge on I phone but dont know how to get to here.Look at post #4 and you can see what Tom is getting in a improved.Then compare. I have another friend on here that shoots a 300/338 LAI and loves it,he cranks them out. I have 2 - 338 Normas so a 300 intrigues me also.

I reread Tom m. Post about 300fog and I am really interested in the cartridge or one very similar.
