    Hey guys
    I picked up 2 boxes of 230gr Hornady hp-xtp,s for 45 ACP and need an OAL for them if anyone has used them in the past. They are longer than the usual 230gr fmj,s that i load so i figured let me ask and see if anyone has used them without any problems concerning length.
    Thanks

    Hornady says 1.23, as well.

    I load them same as the factory stuff... 1.210".

    I'm sure you know that shortening OAL will raise pressures.

    They are slightly longer, but in many guns, must be seated shorter because of the shape. I load them 1.220" to work in all my 45acps.

    With just about any handload, I will seat the bullet pretty far out, just enough to keep it from falling out. I'll disassemble the Glock, for an example, and drop said cartridge into the chamber to see if it fits properly. I will then repeat the process as I seat a little deeper, cranking down the adjustment on the seating die just slightly, until the cartridge drops in easily. Bare minimum. Then, I'll load a mag and cycle a few through to see that they work properly. Mainly, I want to seat the bullet out as far as possible and still maintain proper functioning of the cartridges. I absolutely do not want to seat too deeply and take a chance. You can spike the pressure on a 9mm, for example, to over 60,000 c.u.p. by seating too deeply!

    If I were loading a bottle neck cartridge, like a 357 Sig, getting the proper seating depth would be paramount because of the small neck area to hold to bullet.

    I also double check with a set of calipers against the minimum OAL specs.

    Once it's wired, I'll make notes in the log I keep with every handload I've ever done.....goes back 45 or so years!

    Loading for any repeating firearm, that can cause functioning issues. Most want one caliber of bullet into the case as a min. With some handgun bullets, that is not possible, but you want as much of the bullet in the case neck to allow proper functioning especially for field use.

    Dont know if the g21 is the same but in my g30 a 1.230 oal will work. In my aftermarket barrel I have to seat 1.200 max in xtp and back off some on the powder. Make dummy rounds at hornadys measurements and work down if needed.
