Re: 300 Win Reloading???

I am working on my 300 win at this very moment. I have a 700 26" barrel. I just got done shooting 50 lapping bullets so now I am working on my load again. I am up to 75 grains of H4831 with 200 gr. Accubonds. I just got done shooting my first 5 .003 off the lands and it didnt shoot too well so I am going to load another 5 to verify it wasn't me then work my was out I suppose. I will let you know when I get it done.

Re: 300 Win Reloading???

I use WW that I sort for neck thickness and generally in 300 WM more than 90% (I think it was 95/100) is within my 0.002" variation standard. Probably more likley 90% is within 0.0015". I turn mine just to touch the high spots, but this brass unturned has shot 1/2 moa often enough. Turned was marginally better as I don't cull out the 0.002's.

If you cull mercilessly, you should get great results with WW and probably for a lot less cost than RWS.

I've used Norma in my 375 H&H and found it generally great (consistency), but the primer pockets loosened very quickly and my loads are not particulalrt heavy I don't think. I've seen it said that in various chamberings the Norma brass is softer in the head area, but my experience is limited to the 375 H&H.

Hi Mike! That seems like a stout load are you seeing any pressure signs or have you run any quick load data to see what kind of pressure this produces?

I wanted to try H-4831 but some of my manuals showed 68 gr Max with 200 gr bullets.

Thanks for any info.

Jeff

Re: 300 Win Reloading???

My Rem 700 XCR Long Range Tactical, with a 26" tube, likes 74.0 grains of H-1000, win brass turned, with a Win Large Rifle primer (all I had during load development), 180 grain Sierra GK, almost touching, shoots 0.5 to 0.75 MOA all day long.

I haven't tried magnum primers, but I just picked up some CCI 250's to see if they tighten up at all.

Another load that worked well was H-4350 and 150 grain Sierra GK, shot pretty good.

Re: 300 Win Reloading???

Broz,

My lymann and nosler manual both list 70.5 grains of H4831 as max. The first sign of pressure I had was primer pockets getting a little loose at 75.5 grains after about 3 reloads so I backed off to 75 and have not had any issues at all. bolt lift is good no head expansion not shiny spots on the case head my velocity looks good too. im at 2940 fps. I do have my bullet seated way out so my powder capacity is a little more than average. it just barely fits in my magazine. But it is shooting good I am still tinkining with it but I feel like my 75 grains is safe. I am very cautious of pressure cause its not worth the risk to me.
