25-06 100gr Ballistic Tip & IMR 4350

slipshot · Oct 14, 2008

I have several load manuals and the max load is pretty varried. Nosler 6 - 51 grns, Hodgdon 2008 - 53.5 grns and Speer 14 - 53 grns....I know there is a "safety" factor built in but heck 2.5 grns below the rest???

Anyone got some imput as to what max might be?? Don't want to kill myself or the poor guy at the bench next to me!!!

Thanks guys

Start at 50 up to 54. Nosler jackets are a little tougher than others. Me, I'd start at 51 but that's me.
