So why don’t we all just buy a 30/06 and be done with it?

RR, I’m not sure what I’ve done that causes you to discredit everything I mention, not once have I done anything to create doubt on any of your post, a few years ago you did the same thing you are doing now. Then I was quite and didn’t lower my standard to respond, that’s not the case today. You have no idea of my abilities, equipment or knowledge, maybe listen, maybe learn, maybe not, it seems you know it all already. I misread your post and thought you said.4MOA, not .04MOA, that’s quite a feat for sure. How many times have you posted a group size like that at that distance? I’m betting once! I’ve been fortunate enough to print a group like that once or twice too, sorry no pics, although mine were 5 shot groups not 3. Since I did misread your.04MOA as .4 I have to back out of my earlier statement, I have not shot several groups under that landmark, I have however shot several under .4 under match conditions, not nice calm mornings, that’s under all conditions and yes it was with a 300WSM, I can post plenty of target pics of those groups. That same WSM will agg a 1.75” group at 500, good days it prints 1” bad days 2.5” all 5 shot groups, what does your rifle agg? I’ve shot high score of the year at one of our local matches 4 consecutive years, 3 of them were with the WSM, it won the Worlds Championship 2 day ground hog match with the highest score ever until last year when it was beat by 1 point. That “Inherently” accurate 300 has shot extremely well over the years and that’s why I promote it the way I do, it flat out works as do most guys I know that use a WSM. I haven’t been able to find where Matt Kline’s Heavy Gun 10 shot world record was beat by a Dasher, you may need to post a link, he set it in 2010, I think you might be a little confused, Paul Martinez held light gun record with a WSM, that one in fact was beat by a Dasher in 2014. Both Matt’s and Paul’s records were shot at the 1000 Yard club in Williamsport.

To answer the question about powder in a WSM and WM, no they are not the same, I use H4350 in a WSM and RE22 in the WM. The load in the WSM is 61.xx grains shooting a 210 VLD bullet at 2860fps, the WM is 70.xx grains of RE22 pushing a 190 SMK just under 2900fps. These aren’t numbers read from a magazine these are factual numbers shot over a crony, the WSM is a 29” custom and the WM is a 24” factory gun that’s been worked over. The short fat case and shoulder angle produces an efficient burn rate hence added velocity with less powder, the large case of the Win Mag likes large doses of slower burning powder, it is also an awesome cartridge but when your able to seat the bullets out far enough in the WSM it’s a clear winner.

If you all want to say there isn’t a dimes worth of difference between them your probably right under hunting conditions, but I like accuracy and if you want to be as accurate as possible and shoot the case that’s going to provide you with the best results it’s hard to ignore what’s been proven by match shooters, there is just so much data and information available from guys that shoot a lot and are always striving to get the best results all the time.

Back to the OP, stick with the 300 period no matter if it’s a WM or WSM for the simple reason I mentioned before, Bullet selection, the variety in .308 is equaled by no other caliber, from 125grain to the big heavy 240’s
