My new rifles is going to be ready next week.
Loading for this one is going to be a new experience for me.
It's a 270wsm, Remington 700 action with a 29" barrel. The manual recommendations for powder charges are all out of 24" barrels.
I usually start 3 to 4 grs less than average maximum load out of three or four different manuals and work up from there.
I'm thinking that with the longer barrel (5"longer) the slower powders would be the best choices, (Re 25, H1000, etc...), because I can get denser loads, more powder, 95% or higher.
My question is.
Will the long barrel, 29", develop higher pressure than the standard 24" length?
