Barnes TSX 168 load for a .300 WSM

t*lo said: Hello, I have been looking at the TSX in a 165 or 168 grain bullet for my 300 WSM. I am currently shooting 180 gr. Interbonds with IMR 4350. Can someone please tell me the starting and maximum amount of powder using the IMR 4350 for the TSX 165 or 168. Thank you.

Of all the powders I tested (~10) RL19 gave the best velocties w/ the 168TSX.

*gilent_one said: I never had much luck with the ball powders, probably due to the ES being so high - I couldn't get much consistancy with them. H4831 was pretty consistant, but I couldn't get the velocity (24") I wanted out of it.

I used H4831 and 168gr TSX I got pressure signs a littl etoo early, but of course my rang ework up with 7 differnet loads you coudl cover with a quarter.... As soon as I have time, I will be trying a bunch of other stuff. I have also found that soem of the really slower powders work very well, like R22, RL 25. Everyone seems to be jumping at 4350 and RL19 for this cartridge, but I wonder why sometimes....It's got a similar case capacity to the 300WM (a little less) and the 7RM and those cartridges seem to relaly liek the slooow powders. I intend to try out IMR 7828 SC soon. One way or the other, it's going to end up with 7828, 4350 or 4831, since the Alliant (RL) powders are harder to get rigth now for some reason, and they are 30% more $$$ it seems!:)

m*use said: Yeah I am pretty darn sure the winchester 760 is the powder equivalent. I havent gotten my die for the 300wsm yet, but I am thinking of the 760. I have shot fussion 165 through my gun and have fussion 180 but havent tried them yet. My gun is shooting 1 and a half in groupings at 100 yards with my model 70 (24"). I love the wsm and am not trying to be a premoting whore about it as its my first hunting rifle.

I dont know what comes into play - if it's the capacity or the shape of the case, but for me the faster powder works better. I've reloaded a fair bit for 300WM and the powders suited for it just don't seem to suit the WSM.
