Yes I have manuals and some favorite loads. What I’m looking for is some mild/ just above cast sneeze loads for a bolt action or single shot rifle with cast boolits. I have 3 pre -15 year olds who I’ll be taking out for MI deer season this year and the 450 is allowable in the entire state; I’d like to use some reduced loads that would still be capable of taking deer size game under 100 yards. I’ve not read or seen much on reduced power loads for the 450.
