Hey Guys
Im new to THR and was hoping somebody/some people could help with a bullet seating issue for my cz 527 22 hornet lux
so currently im loading .22hornet using hornady 45gr HP/BEE projectiles into a case trimmed at 1.393. im having somewhat of a problem determining seating depth. im using the age old method of seating a projectile, colouring with a sharpie, loading it and closing the bolt. progressively working down in .005 increments till I lose indication of rifling.
I still have rifling marks all the way around the ogive at 1.675 COL (please bear in mind this projectile is stubby and short being a HP) when I take the next step to seat down to 1.670 and then onto 1.665 I have indication of rifling but only on oneside, two rifling grooves to be exact.
According to SAAMI specs minimum COL is 1.660 for .22 hornet and
According to most, optimal seating depth is .010-.020 off the rifling.
my first question is has anyone had a similar experience with rifling indicating on a bullet like mine?
my second question is should I consider my bullet touching the rifling at 1.675 where it contacts all rifling grooves or 1.665 where only two grooves are indicating on the projectile
and lastly if I was to take the 1.665 as a my bullet touching the rifling would it be safe to go beyond the SAAMI spec of COL 1.660 and seat the bullet 0.010-0.020 beyond the 1.665 measurement. please bear in mind this is a short stubby projectile.
sorry to hit you guys with this arse about question:banghead:
kind Regards
