Tuning With Primers
by Paul Box

We're often asked if primers will make any difference in loads, and in truth they not only can in pressure but also in accuracy.

Each brand of primer has a different priming mixture which will result in both a different temperature as well as duration of the flame. This can have an impact on the burning of the powder due to the different coatings used by the powder manufacturers. Simply by switching to another brand of primer, the very best in a rifles accuracy level might be found.

If the reloader is already at a max load, it's always better to reduce the load by 1.5 grains first when switching to another primer, then start increasing the load again. Primers can be a great fine-tuning accuracy tool.
  Sensitive to Recoil??
by Robert Treece

Do you have a new hunting partner who is sensitive to recoil? Handloading may help. Consider using a lighter bullet of proper construction or simply use a lighter powder charge with the heavier bullet (remaining within the suggested limits). One of these choices should help reduce recoil, therefore curtailing the "flinch" and increasing accuracy potential. So, whether this helps someone with a big magnum, a youngster, a light framed person, or even yourself, if it makes for a successful and humane hunt your goal is accomplished.
Duplicating Factory Load
By Robert Treece

Sometimes we luck out and find a factory load that shoots real well in our firearms and the next thought is "I wonder what's in there, maybe I can make this myself." Whoa!! You can't make that load. Maybe something close, but not exactly the same. The reason; the powders being used by ammo manufacturers are often classified as "non-canister grade" powders and may not be the same as what you, the reloader, and Sierra use as referenced in reloading manuals. Reloading manuals do give recommendations that work well in many firearms. Stay within the suggested increments and enjoy safe shooting.
