got one

I haven't used the 88 but have shot Berger 85.5 using h4350 h1000 and h4831sc. H 4350 I had a good node at 38.6 that averaged 3230 fps. H1000 node was 44.4 gr running 3250.H 4831 node was at 41 grains running 3180 fps start a little below these and work up you should be ok David
 
Thought I could help but I guess I'm using h4831sc. 43.5 behind the 88 at 3250 from 24" criterion. Alpha brass. But can't seem to get more 4831 so I may have to eat into the 4350.
