The velocities are low for a Palma load. For 47gr of Varget in a 30″ barrel, expect about 2950fps

This was an interesting article, although the data is statistically insignificant. I combed my reloading records for similar, recent comparisons; they are noted below. All primers and powders were purchased this year and the groups are five shots. My data is also anecdotal. It would be necessary to fire a large number of primers with as many powder types and guns as possible to derive a significant sample population.

A very nice article with a wealth of good, sound advice for the reloader looking for top performance from their loads. I would simply add that even changing lot numbers of the same make of primers ( or powder!) will have dramatic effects on the performance of your ammo.

Always, ALWAYS, check and recheck when changing components. It will save you a lot of grief in the long run.
