300 Win mag load advice

[Tikka Lover]

73 grains of Reloader 22, 210 Berger, CCI 250 primers gives me 2930 fps out of my Savage 112 26" heavy, fluted barrel. ES in the single digits most of the time. Very accurate, have shot out to 1200 yards with it.

Tikka Lover, are you in or out of the lands with that load?

Yes, into the lands. The Bergers that I have used always shoot best into the lands. No pressure signs at all. It just shoots great.

Im having a lot of trouble finding an accurate 180gr load for my .300 WM. I can get sub 1" groups with factory Hornady loadings, but cant find a pet load that will do worth a poo. I may just step it up to 200gr Accubonds.

That's what I would do. Switching bullets has had the greatest single affect on group sizes in my experience. If you haven't tried a couple different 180s and really want to shoot 180s then try a couple different styles or brands of 180s (except avoid Hornady Interbonds). Then try powders & powder charge weights as the 2nd most affecting factor on your group sizes.

I have wanted to use Nosler Partitons of the 180 variety. But I have tried IMR-4350 and RL22. In the RL22 I have went from 73.5-77gr in .5 increments, and can not get the accuracy I am after. I have shot .665" groups with Hornady Heavy Mags.

I shoot 200 gr Nosler ABs and 210 Berger VLDs in my 300 WM and I use IMR 7828 and H1000. I've never shot a bullet lighter than 200 gr in my 300 WM to date, but my comments are still applicable. If you strike out with 3 different 180 gr bullets, then you could always try different weight. 168s, 190s, 200s, etc.

If the gun is going to shoot well, you'll generally find a bullet/powder combination within 3 or 4 different bullets and powder combinations. I'd start to lose patience with the rifle after that.
