THE BETTER SHOOTING LIST
This list shows the steps that may be taken to get better shooting, more accurate shooting, with cast bullets.
This is about cast bullets and 30 caliber rifles.
Accuracy, here, is 5-shot, 5-group, 100-yard group size averages.
Accuracy, here, is in these categories:
<.5” (We haven’t found a credible report of anyone reliably shooting < .5".
Threshold. Here, it is understood that there is a reasonable, inexpensive, available threshold. For example, variation in shooter does not vary accuracy much, as long as the shooter has a reasonable degree of skill and ability-the threshold.
THE BS LIST OF THINGS THAT AFFECT ACCURACY
If long term group size is between these sizes, the items listed will/may reduce group size:
See: THE BEGINNER'S RECIPE FOR CAST BULLET RIFLE ACCURACY, above.
Improve the shooter’s ability
Try another powder
Use better bench rest equipment
Use a better telescopic sight
Change the frequency of barrel cleaning
Try another bullet
Glass bed the rifle action
Try another bullet lube
Try powder charge increments <.5 grains
Measure or control the concentricity of bullet/case/chamber/?
Use wind flags, a wind speed meter, thermometer or barometer
Change the trigger to one “better than” the Savage Accu-trigger or equivalent.
Fix/improve the barrel crown
Control neck tension
Orient the bullet or case or both
Try another primer
Clean primer pockets, Uniform primer pockets, Uniform flash holes, De-burr flash holes
Explore the relationship between accuracy, BHN and pressure
Shoot bullets in the order cast
Weigh powder charges to .1 grain

Weight segregate bullets in categories < .5 grain
Change OAL in < .010” steps
Change case brand/headstamp
