After you get comfortable with your reloading and using the various powders, etc, and:
If you get the time, it might be interesting to find out what your individual max OAL measures in your own barrel by:
-
No primer and no powder in brass
Run it thru the die to just seat the bullet
If fails, slightly back off a 1/8 turn
Continually do a plunk test until it just passes
Mark up the round to just past the ogive w/ a marker
Drop another plunk test to see if it was really clear
Crimp and retest with marker
Measure the OAL
Insert and remove the test round in/out of the mag 2-3 times to see if setback is experienced from thumb feeding the round into the mag by measuring the OAL again
-
Make 2-3 test dummy rounds (no primer/powder) for the purpose of running thru mag to see if they feed ok while racking with the slide
Compare the measurement to your completed test rounds.
-
Some use this method with start grains and work the OAL back a bit if failure to feed or extract under slide recoiling activity
-
Usually after the plunk and mag feed test, the round usually performs ok
-
Be sure to compare your original recipe of reloaded rounds at the same firing session to compare feel and accuracy. If you have a chrono, that would be interesting as well.
