I would try some 100grn Sierra SPBT. I know my 1:10 Model 7 shoot them okay. If not, then try some 87grn Hornady V-max. H4350 seems to be a popular powder for these weights, but you could try some RL17. I use 37.5grns 4064 w/ Hornady 95grn SST's. I would think you could push them fast enough to negate the necessity of a 1:9twist for 100grn bullet.
