The saga continues , picked up 2k of Hornady 142gr FMJ .355" diameter bullets and now I must put together load data on a bullet that has NO printed DATA anywhere !
So I made 100 + with my starting load of 8.7 gr of 800X @ 1.140" with a very light crimp. Using data from 147gr and 140gr charts. Climbing this ladder should be interesting to do.
Found a load on GF reloading section that I could emulate ; 140gr FMJ .357 with, 9.0gr 800X @ 1.146" using Remington SRP in a G31 . Velocity of 1406fps. I don't use those primers and my bullets are a smaller diameter.
I have a book value for 140gr XTP with 9.5gr of 800X @ 1456fps at 38,000psi so that's going to be the Max load for my Ladder test.
Picked up a pound of Longshot yesterday, the numbers look good on load sheets . Maybe faster than 800X. I have seen some crazy max load numbers on this powder on other forums. They are over book value on weight of charge but still under that max pressure of the cases. I will not go there !
9.1gr to 9.2gr should be about the max load for this bullet with Longshot .
Thinking about starting at 8.0 gr of Longshot this should be about 1400fps with 1.140" OAL
