Re: Published Load Data - How Conservative is it?
I've had a few rifles where the printed max loads could not be safely approached.
Some of the old manuals have loads that are plain hot.
If your velocity is approaching book velocity your pressure is also.
Barrels that are longer, tighter bores, have longer throats, or have different rifling may be faster.
Barrels that are shorter, looser or have smaller chambers and shorter throats are slower.
What that means is that you might well be able to exceed individual loads from a manual due to the characteristics of your rifle but, it won't be a lot, and your loads might very well be too hot in another rifle.
Pressure signs may not show up until well past saami spec..
