    I bought 500 125gr Hornady Action Pistol bullets (HAP). I've read good reports about them, and plan to primarily shoot them out of a 16" Hi-point 995 (9mm) carbine. If possible, I'd like to develop an accuracy/plinking load for the 350 Legend with these bullets as well. Basically one pile of bullets to feed multiple firearms.

    Here's my problem: I can only find load data for 125 gr Barnes (solid copper) bullets (screenshot from Hodgdon below).

    I know it's not the same. Is it reasonably safe to start at 23.7 gr?

    Is it worth investing in a load software to come up with a realistic load? What's your recommendations? Not looking to hotrod/push it to the limit.

    If I was you, I would be very careful of that loading!

    I shoot 250 gr bullets in .35 caliber rifles. Seems to me that going that light you're wasting the bore size.

    The Bar Tac-XP is a sold copper bullet.

    The HAP, Hornady Action Pistol, is based on the XTP with the expansion feartures removed. Is the HAP suitable for rifle velocities?

    The lead core at the same coal should produce less pressure than the solid copper projectile. Solid copper has a higher volume and will seat deeper. I’d say if the hap bullet can handle the velocity it’s safe at solid copper load data. This is just my opinion though.

    The flip side is the 23.7 may be too light. I say this because the 147gr XTP's start at 27.0 gr... I'm thinking this may actually be a better start point.

    @Gatoragn To the point of suitability - if the 147gr's XTP's will hold together at the top end of its velocities, I'm expecting the 124gr to hold together with a lighter end loading.

    I don't see this as a deer load by any stretch of the imagination.

    100% agree. My concern goes with loading too light as well.

    The 125gr HAP's are also 0.356", not 0.355" which will bump up the pressure slightly.

    That's nudging me to use the 147gr XTP data.

    I'll shoot an e-mail off to Hornady and see what comes back as well.

    E-mail sent. In the meantime, an unexpected wrinkle. It looks like these bullets are being discontinued (saw this in my Hornady manual). My guess is as the supply dries up, they'll go away forever... 2020-05-12_07.31.42.jpg

    Reply from Hornady: As far as this being a functioning bullet in the cartridge, I'm sure it would be fine. We have no data to support this loading, and I'm sure that these rounds would all have to be single fed to the chamber in an AR rifle as these HP bullets would likely jam on the feed ramp and shove the bullets down into the cases.

    Called and Sierra has not started on developing load data for the 350 Legend, so that's a non-starter angle...

    Take a look. May give you a bit of info on the 9mm bullets.




    Doesn't seem many have tried the pistol bullets as of yet.

    I see Browning came out with a 124gr FMJ load. It makes me optimistic 124gr load data might one day be available. 2020-05-12_18.45.51.jpg

    I'm sure it will before too much longer.
