No I haven't tried the heavier bullets yet,actually I want to try Bob Cauterucio's 157 grain VLD the BC is supposed to be about .680. I haven't had the time to really get out and tune the gun yet,been too busy working.
My barrel finished at 27.5" I wanted to put a 30" barrel on it but I got a really good deal on this barrel and couldn't justify spending the extra $200 it would have cost me. It's a Shilen 1/9 twist.
Time is a great teacher, but unfortunately it kills all its pupils.
I was reading yesterday that some of the guys using M70 and M700 actions with the WSM (which is based on the jeffries right?) are having trouble with extractions. From what I read, the barrel doesn't have much metal remaining around the chamber with those fat cases and upon firing the reciever will momentarily swell. The brass will swell to meet the chamber walls and when the pressure bleeds off and the reciever and barrel shrink back down the brass sticks the bolt or gives you VERY hard extraction. It's not suppossed to be as bad with a M700 action, as they have just a bit more meat around them than the M70. Have any of you shooters expierenced this? I don't think it's a problem with custom actions, as they are much heavier at the bridges.
That would be one sweet looking barrel. I could go to 32" or maybe even 34" with one like that. Reason I don't flute my 6.5 is they burn out so damn fast shooting comps.. (I might get 850 fom this tube, the lands are already uneven at 617 rounds) that extra $100 for fluting is better spent on the next barrel [img]images/icons/grin.gif[/img] If I can get 2000 from a wissum,, I'll flute. I should start buying standard Douglas' barrels and save the money. Two barrels a season is gonna be expensive. Guess it's time to start buying my reamers.
That mean we might see the CANNON again. If you didn't stake the mat down to the firing line,, you'd take off like you were on a majic carpet each time you touched one of them monsters off [img]images/icons/wink.gif[/img]
My brother has a 338-378wby in a M700. We've noticed no problems in it and it is even larger than the others. Cases will get tighter only after about 4-5 reloads, most likely because of the belt not being sized, another reason for the beltless case. No problems for the first 3-4 reloads though.
I'm sure this problem would be apparent after the first firing if it were really the fault. It couldn't just be their loads are very hot could it? We've ran loads up to 68,000 psi and only then was bolt lift slightly sticky. BR accuracy was just under 60,000 though, a couple grains under the hot load we had.
My brother or father haven't had any problems with either of their Remingtons chambered in 300WSM.
