Maximum FPS Hornady XTP

[sublimaze41]

In another thread there was a discussion about using Hornady XTP in a Muzzleloader.
Sounded like a great idea to me as traditional muzzleloading bullets can be very expensive.

It was discussed that this particular bullet might not do well at velocities above say 2000 FPS.
Can anybody hazard a guess as to the maximum FPS with this bullet or another one with similiar characteristics.

From my personal experience I have pushed 180 grain XTPs from a .44 Mag very hard and they always held up well.

Any thoughts??

The Hornady Catalog states that the XTP is recommended for velocites not exceeding 1600 fps. Yes they will shoot at higher velocites but this is for optimum bullet performance.

The paper chart insert that comes in Hornady XTP bullet boxes lists the .44 180gr XTP (Part #44050) @ 750-1400 fps. Additionally, the 200gr XTP @ 750-1650 fps, the 240gr XTP @ 900-1800 fps and finally the 300gr XTP @ 850-1900+ fps.

Hope that helps...

I've shot the .45 230gr in a sabot from my .50 capper with good results - 1 in 48 twist. over 90gr 3F. but I haven't taken a shot at a deer with them yet.

the .45 cal(.452)240grn and 300 grn XTP-MAGS are made for .460 S&W velocities, i.e. > 1500fps.

I spoke with Hornady a while back about using the standard XTP's in my 454 verses the mag versions. They emphasized using the mag version due to bullet upset with the standard version.

Not sure that the BP initial inertia would be high enough to mess up anything especially using a sabot, but a quick call to them would verify it.
