I just searched this topic and have looked on other sites, but haven't found what I've been looking for.

I would like to load my 35 Whelen with a 250gr Grand Slam. I think, based on other sources, that I should be able to get close to 2500 fps.

Any advice or info?

FYI - the rifle is custom built on a 98 Mauser.

Thanks,

Erik
