Retumbo 300 WSM 210gr or 220gr ?

[elkregulator]

I know Retumbo will work in the 7mm WSM. I was wondering if anyone has tried it in the 300 WSM with heavy bullets or if it is just too slow.

Can't find any reloading info on it, so it probably shouldn't be done. I unfortunately haven't forked out the dough for quickload yet.

Thanks-

Starting loads with 30-06 work to start from in 300 WSM for slow powders.

If you can find Retumbo data for -06 that will get you somewhere.
