If I am shooting a reduced load, (60 percentof max.isok ) max load is 33.5 GR. H 4895 W/150 GR BULLET,reduced load can be 60 % of max.=(33.5÷100=..335 ×60=20.1)so according to my info,I can use /reduce my load of H4895 TO 20.1 GR.FOR A 150 GR. Hardcast,in this case a hunter supply .311 150 gr.HPGC 16 bhn, 10 rds without gc. 10 rds w/ a gas check.bullets were lubed also by mfg. Green waxxy lube ,Rifle is a Marlin 336(1966) exc.cond.bore was slugged using .311 bullet fairly tight micro groove .308 bore for it's years .
What is the est. Velocity of this load?I would like to have an idea before I actually load it,I would like 1500 to 1600 fps.knowing how to figure it would be good also ,my math skills are suspect at times!so please check my figures
