[QUOTE="Paladin300, post: 2056825, member: 115299"] I have a 338 custom built RUM that we are shooting 285 ELDs and 300 OTMs out of and getting between 2775 and 2820 fps with R23 and H1000. We are supersonic to 2100 yards with both loads and bullets. Really liking the 285 over 88.5 grs or R23 with a 3.950 COAL .05 off the lands. It has SDs in the low single digits but not getting any where near 3000 fps. That is pretty impressive from the 338/378. As for the 30/378 I have it has a 1/11 twist. I think I am going to be limited to 225 grain bullets or less. The 200 smks would work leaning toward the 215 otm Bergers since I already have them. I have R23, H1000, R25, R15, W760, IMR 4350, and H4350 on hand. Wondering how R23 would work I have R25 and H1000 on hand. Haven't been able to get my hands on Retumbo in a while. Do you remember what your loads were for R25? [/QUOTE]
