[QUOTE="J E Custom, post: 1929553, member: 2736"] I use H 1000 with the 250 grain AB or the ballistic tip depending on the distance. I would recommend starting at 93 grains and working up. 98.0 will be compressed and in most rifles reach a chamber pressure of 92,000 psi, so it should be safe to reach the max load in your rifle. Retumbo gave me a little more velocity but the max pressure was 65,000 PSI and accuracy was not as good. Retumbo can go critical at higher temps and pressures and may jump several thousand psi with only a tenth or two on increase in the powder charge. I really like the N 570 for my 338 Texan but it will hold 112 to 119 grains of the stuff and I have never tried it in the 338 RUM but with the volume of the 338 rum, H 1000 is a better choice in my opinion. Start low and work up to the most accurate load and you will be surprised at what the 338 RUM will do. J E CUSTOM [/QUOTE]
