300wm 175g Info?

Has anyone shot the VLD 175 Hunting in a 300wm. That's the bullet I decided on and have loaded and shot 50 rds so far. Not grouping how I'd like yet but the brass wasn't fireformed and I only tried 4 powders so far. IMR7828ssc is what seems to be the best to far. Just any info would be great. Thanks.

Are you jumping them? If so how far? Barrel length and twist? Have you tried Imr4350 with standard primers?

I am jumping them but only .10 I have tried the 4350 but it didn't have as good of a group as the 7828. But they were close. Barrel is a McGowen 26" I believe the twist is 1-12 if I remember correctly with out looking at my paperwork.

Retry the 4350 with fed210m or cci br2 primers and push them all the way till you find pressure and then back off .5-.7grns and you should be golden, just neck size only though.

Ok, I will try that and see how it goes. I plan to try some RL 22 and 25 at some point as I've heard good things about them too. I've never heard of doing it that way and that will be the way I test loads from now on.

What brass are you using? Check your neck thickness with a good caliper and make sure all individual brass has a neck thickness variation .002" or smaller. .001" is better.

Consistent neck tension on the bullet is critical to getting great groups and small Extreme Spread. If there are large variations it doesn't matter what powder you use you won't get the results you want.

I just started using Lee Collet dies for it. And measured the neck, they weren't that tight but they were within .005 of each other. The brass I'm using at the moment is remington. It seems to be ok, but I may throw down more money for the next batch. What brass would you suggest? I've heard good things about Norma, and Lapua?
