[QUOTE="Tikka300man, post: 1767836, member: 45224"] I do not see where you specify if you're using standard or magnum primers. With that said, Hodgdon shows a maximum of 58.0 gr of IMR 4831 with a 140-gr Ballistic Tip using the WLR primer. They got top velocity using a maximum of 57.0 gr of Hybrid 100V. Both of these were loaded to 3.330" OAL, using the standard Winchester large rifle primer. If you're getting extractor marks at 57.5 gr of IMR 4831 then you might have a tight chamber. If you can find it, Reloder 26 is an awesome powder and should probably give you the best velocity; although don't overlook RL 22. I've seen people go as high as 63.0 gr with RL 22 but that might be too hot for your rifle. Good luck [/QUOTE]
