For those willing to experiment a bit,try RL25.Check it out in the Barnes Manual with data for the old 130 XLC bullet....max was 65 gr IIRC.

Back off for standard bullets and work up using Fed 215's and find pressure,establish working loads.Doing this in a M70 Classic FW,the 130 XLC gave 3200fps from a 22" barrel with the Barnes max charge of RL25.

Load was heavily compressed in WW brass, but would be less so with standard bullets(lighter charges) and/or heavier bullets.

I wonder what it will do with heavier 270 bullets(?)but have not had the chance to try it out.




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
