[QUOTE="NorCal67, post: 1561579, member: 31753"] I too found Retumbo to be a little more consistent than H1000 in ES in my RUM. I settled at 88 gr, with Federal 215m and Nosler brass. My 7mag prefers H1000, so it's rifle dependent I suppose. I started to see some light cratering at 91gr, and backed off a few grains for an acceptable working load. [U]For me[/U]. With the 215 Bergers, I did not find much change in accuracy when playing with seating depth. When I first started with the 210 VLD hunting bullets, they liked a .004 jump the best. But the 215 hybrids seem to have a fairly wide range I can jump them. Way more than one would think. If you feel you're getting close to max by working up from 88gr in ½ grain increments, then back it on down a couple grains for safety, and tinker in slight increments from there in seating depth and charge weight... if you're a "tinkerer".
