How did you get the 350 Speer to cycle from the magazine? I have to run those thru mine single shot, They bind up the works if I load them to the canalure and sttuf em in the mag!
Rod in Wasilly

Another powder to look into is the H322. I use it exclusivly in my guide gun with 405gr remington or kodiak bullets for 1900-1925fps. It has been the best powder I have tried.

bush man, you have done some fine loading. I too stick to H322 using solids(425 grn.)--keeping it simple.
