I agree with 308win, but what I do to manage this is to always pull ammo from my front pants pockets. Hot or cold, range or field...

I doubt very seriously that your cartridges in the sun at 50° would change 70fps? Maybe in 100°? Carbon rings sneak up pretty fast...

Are you suggesting that being into or off the lands does not affect start pressure (and affecting peak pressure)?

I use QuickLoad to find fastest powder at 104% load density, giving me intended peak pressure (like 65Kpsi) while off the lands (OTL)...

I will tell you this for 100% certainty, shiny, polished chambers are BAD, sanded chambers are GOOD. Rough chambers full of chatter, are...

P. O. Ackley could be a good reference. He liked a 40 degree shoulder, his improved cartridges have more capacity over standard base...

I won't do a bunch of research for you, but higher shoulder angles increase powder burn in the chamber -instead of further down a bore...

So that folks know what this is: https://www.pacifictoolandgauge.com/3-B-Baney-Magazine-Box-310_p_116229.html

Yes it's possible. Powder does not burn at a constant 'standard' in our barrels. There is a baseline standard, as manufactured, but it...

Pressure does influence powder burn temperature per area, by raising powder burn speed. So pressure does affect accurate barrel life...

For your small amount of sizing the bushing choice/result should work. Must be something wrong with the bushing.

I have had issues only when I am trying to resize too much. What’s the fired size of the neck?

Mandrels should work fine in steps. Anneal the neck-shoulder junctions well beforehand, and use a neck lube.

I don't think Bob understands the tool's real potential. He seems unmotivated to innovate a universal version, and I'm sure he's not...

When I load, I go about it in a slightly different way. I seat all the bullets .010 long. Then I go back and measure each round with a...
