In one of the Hornady XTP/sabot boxes, specifically the one labeled 50 cal, 240 grain with the green sabots, those bullets are the .429" regular XTP. In the box labeled 50 cal, 300 grain Mag-Express with the black sabots, the bullets were unmistakably .452" XTP-Mags, even though the bullets aren't specifically labeled as XTP-Mags.

The T/C XTP/sabot box labeled 50cal 240gr with black sabots I have here are .452 and weight 240gr. I checked with my calipers and scale. No matter though I know that I like the way the XTP Mag performed so that's what I will used this year instead of the ones from the T/C box.

That's really strange. I'm at a loss to explain why that is.

dhasemann 09-26-2016 09:08 PM

Yes me too. That is why I created the post. After my test I can say for sure that the T/C package does not contain a 240gr XTP Mag. But I cannot find anyplace, even Hornady's site, where they sells a regular 240gr XTP in .452.

If I can ever get the photo of the bullets to upload I will post them in this thread. Currently I get an error when trying to upload it.

Could you measure the length of the bullets for me? I want to see if they're actually 250 grain XTPs. Alternatively, if you have a scale, you could weigh them to check if they actually are 240 grains.

I weighed them and they are definately 240 gr. The Mag is a little taller I will post the actual measurement tonight.

XTP Mag measures .681 in length and the Thompson packaged XTP is .640 in length. Both are .452.
I would post a photo but I have given up trying to do that here. Just says upload error and I am tired of wasting my time.

dhasemann, you have to upload a pic to a host site like photobucket or wherever. Once you do that, you copy the image address and then paste that into the photo popup when you click on the postcard looking thingy.

A .452" 250 grain XTP is .661" long, and a .429" 240 grain XTP is .704" long. I think we've definitively proved the bullet in the package isn't any of the bullet normally offered by Hornady. I just wonder why the'd do that, though? Doesn't make much sense to manufacture an entirely new bullet for their muzzleloader when they already offer several similar weight pistol bullets.

No you dont. You can upload to your own album here too. You can even add them as an attachment.

Neither one of these pics is from a pic hosting site. I uploaded them directly to HNI.

Some photos of the 240gr XTP Mag and the 240gr T/C packaged XTP.

XTP Mag on left and T/C XTP on right in all photos




These were shot into 1 gallon water jug at 50 yards 2 pellets of 777. Both found in 4th jug. As you can see all the copper peddles are gone from the T/C XPT bullet.
