I'm curious of accuracy between what I use at bench which is Uncle Buds Bull Bag and shooting from bi pod with rear bag. Depending on burr at range I am either having bull bag on bench or putting 2x2's under it. Never seems level. I have taken a deer at 515 yards with 257 weatherby off a bi pod but have always been advised not to use one off the bench. Lead sled is in dumpster. Can't feel the rifle. Have front and rear bags also but rear bag always too short or in my face. Have been thinking about front rear rest with adjustments but am curious about the bi pod. I only use it at the range with AR just to keep magazine off the bench. Not shooting it for precision though. Just silloutes. What's your take?
