Looking for anyone that has used these in a 300WSM (Blaser)and had any good load results. I have loaded up a few different reciepes with less than acceptable accuracy. Also how about bullet performance results on deer size game.

I've used the 150 gr. SST in my 308 extensively with several 1 shot kills on deer size game. The factory load grouped mostly around 1.25". I've been working on loads with the 150 gr. interbond and have so far gotten acceptable accuracy of just around 1", this in a Ruger tang safety RSI model. Sorry I can't help at the velocities you are running but at the lower 308 velocities they seem ok. I've been using H380 and getting around 2760 FPS in this short barreled rifle.

Thanks for the info, I have been somewhat frustrated as to why I cannot get this Blaser to shoot under 1.25" at 100 meters. I never had this problem with any rifle I have owned. My first barrel on this gun was replaced due to too much headspace and excessive throat length, the new one seems to measure better but still cannot get 1" or better groups. I have a 300 WSM in a A-Bolt that shoots .75" or better with many loads. Possible I should not have given it to my Son!!
Has anyone out there had similiar difficulty with there Blaser rifles?

Mohunt, just as a thought you might want to try the 165 gr. Hornady. It's a little longer so can be seated farther out and might help with the long throat. I shoot these in my 300 Win Mag BLR and normally get around 1-1.25" groups with them. Which to me is acceptable accuracy for a lever rifle.

You can't always "force a gun" to "like" a certain bullet.
I'd say try some other sized premium bullets like the accubond, tsx. partition etc etc. Something out there might work better.
Getting together with a friend and "sharing" a box or two of bullets makes testing more economical--there ain't nothing wrong with a 1" gun at 100 yds. I have a 300 wby that likes 180 grain barnes x bullets---I almost "didn't realize how good the load was" cause it only shot 1.25-1.5" at 100 yds but at 300 yds it does nice round 3-3.5" groups. (now I have to try the tsx and see if it's better). But I'm not sure I can shoot much better than that off a rest with a thick cross haired 10x scope.....AND I CERTAINLY CAN'T SHOOT BETTER THAN THAT FREEHAND IN THE FIELD!!
