If this is for the bullets you received from me, disregard the OAL as the Lyman bullet is shorter. Try seating to: 1.145-1.152 Taper crimp at .377-.378
For what it’s worth….
I have been loading Donnie’s 147 grain FP’s with 3.5 grains of TiteGroup
Have notes where I increased the OAL to 1.150
Been shooting them in an STI and a Sig MPX, could probably go softer but damn they slam the steel plates
Here comes the disclaimer-Don’t blindly follow any reloading recipes on the web without working up your own ladder
3.0grs was perfect! Shot some this past weekend & it will be perfect for plinking!I also have some of the 145 round nose that I’m loading with the same recipe
