I have found very few bulletsI couldn't get to shoot decently as long asI kept the charge under 110 of ffg T7. My most used is the 44cal/240xtp mmp green sabotwith 95gr of ffg T7 & 209W primer. 1.5" or better and has worked well on deer from 30 to 170 yards. 250 SST under 100-110gr ffg T7 also works very well if 100-200 yards is the norm when hunting.

Make sure to dis-assemble the bolt to clean after every range session.
