All guns shoot different and will perform differently. It sounds like you have a load that you are satisfied with. That is great, but it would amaze alot of shooters the kind of groups that can be acheived with hand loading. I shoot a weatherby in a .270 win and also use a 130 gr. bullet. I use a speer spitzer 130 gr. with hogdon 4350. One big factor in accurate loading is the head spacing in the cartridge and that is something a factory load cannot match to a particular gun.
