[QUOTE="Trnelson, post: 1216610, member: 42308"] I played with h-1000 with the 230 Berger in my 30/338 win. Mine is throated to seat the 230 Berger OTM base at the neck / shoulder junction in the case. I started at 64g h-1000 and worked up to 70g. I gave up on it there as I never found anything that my rifle liked. Top velocity was 2760 fps with an SD of 23 IIRC. However, it just wouldn't tighten up any better than about 4" at 300. I switched to Norma 217 and worked up from 68g to where I found best accuracy at 76.0g and 2740 fps I never tested anything higher as I'm seeing an SD of 9 fps with the 230 OTM from 234-238g Winchester 338 win brass necked down and fire formed. I'm using winchester large rifle magnum primers. H4831sc also looked promising, but I didn't finish testing it after I started working with Norma 217 and everything I loaded had an SD <14 fps and grouped better than MOA IN MY RIFLE. Start no higher than 64.0g H-1000 and work up, there are a ton of different 30/338 win reamers out there!!! My friend's has a tighter neck dimension and shorter leed to the rifling (his is throated to shoot the 178g AMAX) and his rifle topped out nearly four grains less than my rifle. My old 11 twist barrel wouldn't take anything longer than 3.30" I'd also consider the new temp stabile IMR 4451 or the slower IMR 79xx 30/338 Win is a great chamber, very flexible with useable powder and bullet weights. The new slow and stabile powders really make it shine. I'm on my second barrel and planning to build another rifle so momma will quit stealing mine every time we head to the stand or range. [/QUOTE]
