None were really bad, just not as good as I had hoped.

I tried a couple other powders with no luck. Never found a bullet that shot well in the 300wsm with the IMR4350, so I switched to H4831, another powder that I nearly always have good luck with. I tried several different bullets with IMR4350 which shoots well in many of my guns. I have a 300wsm that I bought partly because I had read a lot about the great "inherent" accuracy of the cartridge. The kid will be using it next month on his first elk hunt.Īny help from you guys would be MOST appreciated! 300WSM? I've loaded 60 grains of it for 160 grain Speer Grand Slams in my Steyr Model S 7mm Remmy for years and it loves that load. There's a load in the book using IMR4831 and I have a bunch of it already. I've got a ton of Remington 9 1/2Ms on hand but also read the Federal 215 is a good one. I'm not best friends with Mother Nature, but I'm thinking I won't be hunting in super cold temps here in NM. The books and some folks say magnum primers, others say regular. I've heard there's a temperature tolerance difference between the two powders, but are they that much different, performance-wise? The loads they have listed run from 61 grains 2861 FPS up to 65 grains 3024 using the IMR4350.Īs far as primers, I've read different opinions as well. Of course I rushed right out at the time and got the powder without writing down the recipe! I picked up the Nosler #6 book the other day, but the only 4350 they have listed is the IMR. I remember seeing some load info using H4350 with Accubond 180s before, but I can't seem to find it now. 300 WSM and have gotten great performance out of the Winchester Supreme 180 grain Accubonds, but I'm thinking I can load a box for less that 54 bucks! Sorry bout that! I've got a Tikka T3 Lite. I posted a question on another thread and realized afterwards I shouldn't have tried to hijack it.
