Thread: 38 super major loads

I had quite drastic readings in velocity between length of rounds vs same weight of powder using the same projectile but cant seem to replicate it to the same extent again, but there is a difference.

Using round nose throws my data off due to seating depth in the case, so my suggestion is for you to load it as long as possible that also fits in and feeds from the magazine and start at 8 grains of powder.

You will know within 3 rounds over the chrony what you need to do next and im certain it will involve an increase in powder weight.

And as for crimping, well it depends if you flare the case mouth, i just resize and seat, no flare, no issues in 2 years so im happy with that.
