todbartell260 Rem w/ 140 gr.
What type of speeds are you guys getting with 140 gr. bullets in your 260 Remington?
I have a M700 with a 22" tube.
Here is what my handloads chrony at:
140 gr. Speer SP/RL25 (50.0 grs.)~2713 fps
140 gr. Sierra BTSP/IMR 4831 (43.3 grs.)~2531 fps
140 gr. Sierra BTSP/RL19 (45.2 grs.)~2571 fps
140 gr. Sierra BTSP/RL22 (46.4 grs.)~2704 fps
140 gr. Nosler Part./H4831sc (46.0 grs.)~2629 fps
Does this seem normal? I think I got a slow lot of RL19, but all loads seem to be max, as primers seem to be flattened just a bit. The RL22 & H4831sc loads shoot great, sub MOA.

Bobby TomekFrom a 22" barrel, you should safely be able to achieve 2700-2750 fps -- so most of your loads are right on the money. In my usage, H4350 produced best velocities in the 6.5x.308 (aka .260).

todbartellI just tried some 140's with 7828 (47 grs.) and WXR (46 grs.). Velocity was 2600 fps for both.
I think I will focus on RL22 for my 140 gr. loads.
