I am currently loading up some 140 tsx for my rem 7 mm mag using fed 215 primers and RL 22 . I have worked up from 66 grains and am now at 69 1/2 and getting only 3181,with no presure signs. I would like to know where presure signs begin , knowing that rifles will vary , is any one getting close to 3400 , thanks for any help, John G
I don't know much about the TSX, but I get 3350 FPS from my Ruger No. 1B, 26" barrel with both the Nosler Partition and Sierra 140-grain bullets using71.5 grains of
OLD HODGDON SURPLUS H4831 in WW brass with Federal 210 primers with normal pressure indications. I understand that this old H4831 is slower than that sold today??
I was
NOT ABLE to duplicate my old N205/Norma MRP load of a 175-grain Nosler Partition with MV of 3070 FPS using RE 22. But I was able to do this using
IMR 7828 with the 175-grainer.....
