Welcome on the board, BTW. Generally happy to discover a fresh member. Check out all the opposite discussion boards way too, and be sure you bounce in the discussions.
If the velocity big difference is below 5%, then Don't be concerned over it. For ball-park estimates, a five% velocity change corresponds to aprox.a ten% tension modify. At everything lower than absolute optimum masses that won't substantial, and it is often near to usual variation for a load.
Should you be on MAX LOAD you will need to even now get the job done up. Same factor you would do if you have a unique lots of precisely the same primer. Same point you'd do if you change one particular ingredient into the complete reloading equation.

(I'd only reported that I was being forced to use a lot of stress within the deal with to seat primers in commercial situations.)
All They are really indicating is that may be the combination which was utilized to build that published load. When you are loading considerably below the maximum shown demand then load some rounds with Each and every and chronograph them. There may be between no transform to an important a single with the higher normal velocity indicating a greater normal pressure.
Give me a number of additional loadings with those in any other case correctly good conditions along with a location to make use of the "Extra fat" primers .
