    I picked up 2k of their 115grn jhp pills to shoot from the family Glock launchers. Loading on a Dillon 650 if that matters. Just punching paper and shooting steel.

    I have 8lbs of Titegroup to burn. Also have some WSF.

    I'm having trouble finding data on these. Anyone loading these or know a source for data? I've sent a few emails. Pretty bummed. Wanted to be shooting test loads and start pulling the press handle.

    The bullet shape only matters for O.A.L. Your recipe can be for any 115 grain jacketed bullet.

    You want to leave the same volume inside the case as the recipe calls for. So if your JHP bullet is (for instance) .015 longer than the FMJ bullet called for, you want your O.A.L. to be .015 longer.

    Disclaimer: That's how I make adjustments. You are responsible for your own actions.

    That's my concern is how much bullet is in the case and how to adjust powder charge accordingly. I'll use my barrel as a guide and see where I land and see if I can compare it.

    Hopefully PD can give me an idea on oal. They do load and sell these as loaded ammo.

    Thank you for the input

    Got a little help from Enos forum. 1.135 seems money for OAL. Plunk tests good, spins free and cycles by hand smooth. Any shorter and they would hang up.All my guns seem to have a large throat. Don't hit lands until over max SAMMI spec.

    PD said they load their factory ammo at 1.100 and to start at 4grn of titepoop.

    Think I'll load at the 1.135 and start at 3.8 or so grains of pow pow and ladder up to 4.5.
