So this year i was invited down to Montana for an antelope hunt. Now i use to shoot 160 grain winchester accubonds out of my factory Remington model 700 BDL and it use to shoot between 1-2" at 100 yards. Not really the accuracy i wanted but it wasn't bad. I went out to the range one day and found some 140 grain bullets just sitting in the back of the cabinet so i brought them instead because the 160's were expensive. DID NOT adjust the scope, just through one in the chamber, took aim and squeezed the trigger. about 1" low of dead center. Put a second and squeezed again, perfectly horizontal to the 1st shot only just off to the right, but still touching the hole of the first shot. 3rd shot was just a little off to the left but was almost through the first hole. 4th shot i decided to aim up about 1" and hit bulls eye. 3 shots under an inch and 4th shot bulls eye. I decided that i would now be shooting 140 grains instead of 160 grains because it seems to be that my gun prefers the 140s. I picked up some 140 grain Nosler Accubonds and i need to put a load together that would be good for close and far. Now i know this bullet can perform extremely well, all i need is a good flat shooting load. I have some H4350 powder, 140 grain Nosler Accubond heads, Remington 9-1/2 magnum primers, Remington and winchester shells. How much powder should i load? what kind of velocity should i be expecting.
