I have a Bubbafied* Gew. 88 JS that I load for... I use 170 gr RNSP ... and though the books call for a max of 36 gr IMR 4064.... anything less than 40 grains leaves the cases sooty (not enough pressure to expand them and seal the chamber) .... I have found that best accuracy is at 42 gr. ...... I get about 2150 f/sec .....




* Barrel jacket removed, and barrel cut down to 18" ...... stock (very beautiful wood!) sporterized......
