Anyone load/shoot/compare the 158gr XTP (#35750) vs the 158gr XTPFP (#35780)?
I’m curious at the penetration, expansion and performance of the two comparatively. I’ve kinda given up (at least temporarily) on using hard cast in my particular M28. I’ve found it difficult to zero in on something it likes. It seems to eat and spit out XTPs well though, so I’m going to just focus on that for the time being.
Thanks
I'd be very skeptical of the FP opening as well as the regular XTP. Might be great in a lever rifle but they have the FTX for that.
Tagged for curiosity.
Never thought of the lever gun angle. I could call Hornady too...ask the source. Maybe I’ll do that tomorrow.
I haven't tested the 158s but the 140s hold together in water from rifle and handgun. 1150fps to 1650fps

Mr. Xxxx,
Thanks for the inquiry. The 35780 FP-XTP will have a higher velocity rating in case used out of longer barrels or slightly faster cartridges. For your application either will do the trick and should have about the same expansion velocities. We appreciate your business.
Thank you
I’m going to stick with your above graph nonetheless.
Thanks for posting that graph. I'd heard about it, but never seen. Very useful. Thank you.Quote:

Check the BCs. Without looking it up, I think I remember the BC of the FTX is lower than the FP.Quote:

Small spread loaded up. 13.0, 13.5, 14.0. I have 14.0 listed as a good load from 2014. I never got velocity tho. This time they’ll go across the LabRadar. Looking thru data, I can poke above 14.0 a ways, but I’ll see what 14 even gives me first.
Ran the quick test. 13.5@1190fps seems the best of the three. Running about 1 3/4” at 20yds. I might do some research and go a bit above 14.0 and see if I can find the next happy spot. The 13.0 ran about 1170fps and the 14.0 about 1210fps on average.
I dragged along a box of the Lyman 358156 GC’s. Pretty impressive performance from them. I’m running 15.3gr of H110 with those. They clocked at an average of just over 1280fps and all (12 rounds) went into a group just shy of 2”. A couple of pulled shots on my part, the rest were basically one big hole. I had shot this loading on an indoor range in the spring, but didn’t run them over a chrony. I need to make more of these! I had similar performance from the standard #358156 (non gas checked) using .38spl cases and running 10.5gr of 2400. 1-1 1/2” groups with those at 15yds IIRC...
I’ve settled on 14gr if 2400 with a 158gr HPXTP for my 6” 686. Here are a couple of the targets from it. Attachment 93177Quote:

First pic has a group at 13.5 as well. Best I can recall there are 8/10 in the red circle with the 14gr load at 15 paces, I don’t remember throwing any of them and I usually shoot two groups of five. Second pic is 10 rounds at 25 paces. I need to chrono them and see where they are at.
I’d bet around the same speed. I used magnum primers. I might try standard as I read (on the in-ter-net) that standard gives better results... Might try H110 too.
Hell...if I knew the #358156’s were clocking so fast, I might not have ordered the XTPs up. Always nice to have options tho.
Oops...you’re running 6”. Nevermind.
Those were loaded with standard primers. I’ve heard good things about H110 but haven’t tried it myself yet. I’ve never tried the #358156’s. They are a classic but I agree, options are nice.Quote:
