250 Powerbelt Aerolite VS 250 Thor Hollow Point

I put this test together this evening with the CVA Apex .50cal 25" barrel, 1:28 twist. 100gr Blackhorn209, CCI 209 Magnum primers.

3 to 5 minutes between shots for barrel cool down.

The Thors were from my sizing sample and therefore, not the ballistic tips I normally shoot. These were .500" and load just like a powerbelt.

Now I am not sure what distance Powerbelt tests their velocity, but their info is MUCH lower in velocity than mine. They show it doing 1820 FPS. I checked the BH209 website and looked at the info they listed for the 300gr Aerolite which was 1831 FPS and Powerbelts website lists it at 1816 FPS. So again, not sure what system Powerbelt uses for the info given, but its off.

I did my testing at roughly 14 to 15 feet with the Chrony Beta Master with no sun shades as it was clouded over.



Green markings are the Aerolite with NO Gas check at the base. Powerbelts I hear, shoot the same without this gas check in place.. Hmmm, interesting, especially since the velocity changed greatly. Along with point of impact.


Thor = 1989 AVG velocity
Aerolite = 1914 AVG velocity
Aerolite with NO gas check = 1865 AVG velocity

Velocity in the heat was only 7 FPS faster than it was in the winter when I first chronoed the Aerolite. Velocity in the cold was 1907 FPS Average.

When my order of the ballistic tip thors comes in, I can see is there is any difference in velocity with those.

But again, Powerbelt lists the 250 AL doing 1820 FPS with a 100gr Blackhorn209 charge. I think they may be testing at a much further distance?

Maybe they tested with a different rifle, or one with a different length barrel, or something really unusual like that.

Maybe a pistol, but i highly doubt that.

Do you really believe that shooting a few rounds over a Master Chrony and getting different velocities than the bullet manufacturer lists is enough to conclude that the bullet manufacturer's data are "off?"

yes, I checked on the blackhorn209 website as well, Powerbelts info is badly off for the aerolite with BH209. I can check their pellet stuff and see about that as well.

Its more than a few rounds, ive been shooting for a chronograph for years.

At 1820 FPS, My 58cal round ball shooter, shoots faster than an aerolite with 100gr bh209.

If you really believe the information you've presented in your post above is sufficent to conclude that the bullet manufacturer's data are "off," do yourself a favor and run it by some guys who do this kind of testing for a living. Cut and paste your post into the gunwriter's forum and ask Mule Deer if your data are good enough to conclude that the bullet manufacturer's data are off.

Be sure and mention that it's one day of testing, and be sure and mention the make and model of your chronograph.

Hell's bells, you don't even know what barrel length the manufacturer used.

lol okay how about you do some chronographing then my friend.

Exactly, I said i have no clue what gun or what distance they set their testing up at.

I know western powders uses barrels that are not even on guns.

You supporting powerbelts velocity info though only shows how much slower the powerbelt really shoots. 1820 FPS?!! I say a typo someone over looked.

Why would I waste my time chronographing a bullet I don't shoot at a velocity I don't shoot, I'm not the one trying to prove something here. Why would I chronograph anything with a Shooting Chrony and then think I had good enough data to conclude that the bullet manufacturer's data were no good?

Why don't you post your data in the gunwriter's forum, tell the gunwriters you've concluded that the bullet manufacturer's data are no good, and see what they think? They're experts. You and I are not.

I don't think you get what I'm saying here. I'm not "supporting powerbelts velocity," I'm saying that what you've done here (once again) proves nothing.


It is telling though. It shows that your experience in evaluating chronograph data is fairly limited. Shooting over an inexpensive chronograph, especially an inaccurate one with the short distance between the screens that you're using provides useful data, but even with a quality chronograph it's very common to get field data that don't match what the bullet manufacturers show in their manuals.

And it's not because the bullet manufacturers' data are "off." Different rifles shoot different velocities. And your chronograph and the tests you've run aren't good enough to negate a bullet manufacturer's data.

My main use of a chronograph is for testing centerfire loads. In lots of different chamberings, makes, and models of rifles. It's fairly common to get velocities that don't match the loading manuals.

And all this time, I never knew that I was right, and they were wrong. Who knew?

I don't know about all this, but I do know I have killed elk with one shot, bang/flop with a Marlin 94, 44 mag carbine using 240n grain Speer Semi jacketed flat points going about the same velocity of 1800 fps and nothing was lacking. I think some guys get so tied yup in this minutia that they think the elk now days have kevlar hides.

Anything in the 300gr bullet weight realm with a suitable powder charge out of a muzzle loader is going to kill an elk if placed right.

im just showing how much better the thor is when it comes to velocity and the fact that you can push them as fast as you want.

and yes, there is NOWAY the powerbelt aerolite 250 grain bullet is 1,820. Thats way to slow with 100gr BH209. Their info is off.
