After some research, I decided to try the new 200's in my Sendaro. H1000 with W-W brass, Federal 215 primer. With no published data, I started at 73.0 grains and worked up to 79.0 with no pressure signs. The 79.0 three shot group had a velocity of 3010 average. Accuracy has been getting better the higher the charge, the 78.0 and the 79.0 were around 3/4". I have loaded some more loads at 79.0 and 79.5, as soon as my shoulder recovers I'll do some more testing. I feel I'm close to max in this rifle. Seating depth is just shy of touching, as I will probably single load these. This is a target bullet and will be used for banging long range steel and paper. It is designed for 10 twist. The F class guys are using them in their 308's.
