Hornady's Velocity Ratings For XTPs

Semisane · 06-24-2007, 11:20 PM

I bought abox of Hornady .451 185 grainHP/XTPs at a gun show today. It was the "old" styleblack & white box with perferated metal reinforcing strips on the corners - not the red & white box Hornady is currently using.It had a paper slip inside that I have never seen before. It states:

"XTP bullets were designed for best performance at a range if impact velocities given below. This range has been found to be optimum for maximum penetration and expansion.

#4510045 Cal-185 HP/XTP 750-1450 fps
#45140 45 Cal-200 HP/XTP 700-1250fps
#45160 45 Cal-230 HP/XTP 800-1250 fps
#45200 45 Cal-250 HP/XTP 800-1600 fps
#45230 45 Cal-300 HP/XTP 800-1700+fps "

Does anyone have a chart like this for Speer Gold Dots or Sierra Sports Masters?

(The paperalso had velocity ranges for 9MM, .357, 10MM, .41 & .44 calibers. If anyone wants any of those just say so and I'll post them.)

Thanks semisane. That explains why the xtps may group better with 90g of 777 loose than 100g for me. I don't have the 777 jug in front of me but I think at 100g, 777 maybe at the high end of those limits.

if you are going to push XTP's hard faster than say 1700 fps you need to get XTP/MAGS the regular XTP's will shear jackets in flight if ya push them to fast

I've killed many deer and dozens of hogs with the 240 grain .44 caliber XTPin my muzzleloaders. Powder loads varied from 100 to 150 grains of Pyrodex pellets and Pyrodex RS granular. 95 percent of kills were bang flops. Never had one fail. If you want high retained weight use the XTP Magnums.

Am now using the 250 grain SST for my deer and hog hunting. It is a little more accurate than the XTP inmy favorite gun.

Hey oldrookie, those velocity ranges have to do with the performance of the bullet upon impact. I doubt it has any effect of accuracy, but anything's possible.

You're right, falcon. The .44 caliber XTPs appear to be a little tougher. The chart doesn't show XTP Mags. Here's what it does show for .44s.

#44050 44 Cal-180 HP/XTP 750-1400 fps
#44100 44 Cal-200HP/XTP 750-1650 fps
#44200 44 Cal-240 HP/XTP 900-1800 fps
#44280 44 Cal-300 HP/XTP 850-1900+ fps

I wish all manufactures would include data like this with their bullets. I couldn't find anything like this on the Speer website.

That really is some interesting information on the XTPs. Maybe when people saw the bullet"splatter" it is because they are pushing the bullet too fast, or the animal is so close it just has not had time to slow down.

A lot of companies used to provide such data with their bullets. I have one such chart laying around here for the REAL conicals somewhere. Although the powder charges they were talking for the best results were very very low.

Those .44 calibers can be pushed harder... wonder why? More streamline maybe?

Probably heavier jackets on the .44s, since they're made primarilyfor the .44 Magnum revolver.

The .45s are probably designed around the .45 acp for the lighter bullets and the .45 Colt for the heavier ones.

"Probably heavier jackets on the .44s, since they're made primarilyfor the .44 Magnum revolver."

They are also used in the .444 rifle round.

That would make sense too. I shoot a 240 grain out of my Ruger Redhawk .44 caliber and they really make a hole through a deer. But at least the deer goes down which is my main concern.
