Re: 300 Berger or 300 SMK for hunting?

I just bought some SMK 300 gr to shoot out of my 338 lapua. I can't seem to get the Bergers to group. Going to try one more time and then, I'll load SMK. MAY LOAD SOME OF THEN ANYWAY. Just trying to get it to work. Retumbo and fed 215 in lapua brass is the rest.

The only funny thing I have found with the bergers & even called Berger and they confirmed is they have a sealing ring right wear the boat tail connects sizing at.339 it gave me some trouble when resizing with Wilson dies the bullet would fall into the case.

That was the answer I was looking for. I will load some SMK's tomorrow and go way beyond my previous loads and see if I can speed them up. The Bergers may have to be seated deeper in the cartridge to gain more speed, since the OAL has changed dramatically. When the barrel was new, my max OAL was 97mm with the Bergers. Now it is 103mm. And I am still not in the lands ;) But since the SMK has a different shape, I might hit the lands and speed them up. I will try 93-94 and 95 grs of Viht N570, and measure the head with a micrometer tomorrow, after firing. My accuracy load has allways been 89 grs of 570, giving my 855 m/sec, but now I get 830 m/sec. 93 grs of 570 behind the OTM was only 838 m/sec yesterday, and that is slower than anything I have. Last year they were 883 m/sec, using the same charge.

I have ordered a new barrel, same as this one, but with a 1:9 twist. Lothar Walter, SS, Match, 32" long and 1.10 inches at the muzzle. It will not be ready until december, and then the hunt is over.

Thanks for your input guys, it is allways a pleasure
your max OAl of 97mm from OGIVE to base ? Also how far off lands ?

I'm having the same issue!! When I resize and then seat a bullet, it's loose. Sometimes. Not
Always
