338 win mag and 300 gr bergers

I have seen a few threads on some of the more powerful 338's,but if there was one on the win mag I mised it.I was given some 300's and got to wondering if the win mag has enough power to even bother with a bullet that size.

I wondered about it too. However, HSM load them (stock# BER-338WMOTM) page 53 of 62 http://www.thehuntingshack.com/catal...roductList.pdf.

Not sure of barrel length tested but they have it advertised as MV=2400 FPS and ME=3838 FT-LBS.

Most I think feel that it just doesn't have enough powder capacity to effectively propel the heavy projectile to take full advantage of its full potential out of the .338 Win Mag.

Having said that, I'd say go for it and explore ... and please do share!

Good luck and happy safe shooting/hunting.

Thats about the same as Bergers web site.I was just hoping someone had used them and had any idea how they shot out farther than 100 yards.I guess I'll have to just load some up and see for myself.I found a load using760..I'll let you know what happens.

Re: 338 win mag and 300 gr bergers

I have a 24" barrel 338WM.

So far I've shot:
225 A-Frames - Very nice @ 2775
225 TTSX - Very nice @ 2760
285 Hornady BTHP @ 2500, not what I'm looking for but OK for bang therapy.

I have some 250 Noslers, 250 Bergers and 300 Bergers but I'm saving those for the bigger 338's

If it were me: Stretch the COAL out as long as you can to get the powder capacity.

Re: 338 win mag and 300 gr bergers

If you're looking for any kind of long distance performance out of running the 300 OTM, your Win Mag just won't push it fast enough to create an advantage. I would consider the 250 grain Berger. Just my 2 cents.

Re: 338 win mag and 300 gr bergers

I agree that any 300 grain bullet is too heavy for a 338 win mag. Trajectory and velocity at long range suffers far too much. IMHO the 338 win mag is at it's best with 225 grain bullets and a 26" barrel. 250 grains is max weight for the win mag but I think is still very effective.

Re: 338 win mag and 300 gr bergers

I thought this is the info I would get back.The largest I every shot out of my 338 was a 215 sierra.It does real good out to 300 meters then it's like falling off a table and fiquerd 200 would probaly be max out of this gun with the 300gr.I was given the 300's and wanted to see if anyone had tried them.I found a load of 56 to 59 grains of 760 powder.I'll let you know.Thanks
