300 Win Reloading???

I was wondering what is the ideal powder for the 300 win mag with 185-210gr bullets. Which brass seems to be better quality, norma or nosler? Also any pet loads would be appreciated. Thanks

Re: 300 Win Reloading???

H-1000 is my go to powder for the 300 Win case. With a CCI 250 or a Fed GM215M and a 210 Berger close to the lands.

I would start at 74 gr and work up 1 gr at a time. Usually in a 26" barrel I find a sweet spot there or just above if the rifle will let you go up in powder charge.

Cant help you on those two brass selections, but I saw some RWS for sale on Snipers Hide a while back. In my opinion the only thing better than RWS is Lapua which is not made anymore.

I have been getting great results with H1000, cci 250 primers, winchester brass, and 190 gr berger vld. Start out at about 74 and go up from there to a max of about 79.5grains. Bullets seated 0.015 from the lands. I am also doing some testing with retumbo and some other bullets.

I know it depends on the rifle, but are you guys able to load your bullets close to the lands while still being able to feed from the magazine? Thanks for all the suggestions, I have both retumbo H1000 so Im happy about that. Thanks

I am loading H-1000, CCI 250 mag primers, remington brass and 180 grain barnes ttsx bullets. As others have stated start low and work your way up. I found where the max was. I am loading 2 grains below max. The barnes bullets are seated .04 off the lands. My gun has a wyatts box mag so oal is not a problem.

Re: 300 Win Reloading???

Ovatafford, I have never had a problem getting to the lands with a factory mag box and 210 Bergers. This includes two 300 wins that were chambered with standard match reamers and also a few 700 Senderos I have worked up the load for. I better add , please start low with the powder charge of H-1000. One of the senderos started showing pressure signs at about 75.5 gr. It shoots very well and is now happy at 74.6 gr and we shoot it to 1400 yards.

But others are just as happy at 77 gr. So there is no way to know what your rifle will like other than starting low and working up.

If you have some Lapua Headstamp brass you have the best brass you can get for this rifle. IMHO, and if you feel any reason to use something else I will be glad to buy your Lapua brass from you...

Jeff
