- IMHO Henry is not missing anything here. The OAL maximum has
- significance primarily in the physical seating, headspacing and
- operations arenas. The net case capacities do affect powder
- performance but the other variables (powder batch, powder age,
- primer type & brand, crimp pressures, bullet diameters, bullet
- lubricants, seating depth etc.) mask that one variable's effect.
- Thoughtful handloading will minimize the effects of variables
- other than powder type & weight, primer brand & type, bullet
- type & weight so that one can focus on optimization of a load to
- meet the shooter's velocity, power factor, trajectory, accuracy,
- bullet performance etc. requirements. The one caveat re: case
- capacity is that you shouldn't use too small quantities of slow
- powders(handgun H110/296) in large cases because the powder can
- explode rather than burn quickly. Otherwise case capacity and OAL
- considerations if within spec. can be discounted for load development.
