You have any of this ammo you would like to share for testing? I would love to do some testing.
MRG: Why? I'm not the one spamming gun-boards with his YouTube tests.
Look, I appreciate the effort of anyone who does this sort of chrono & ballistic testing, but my point is if you're going to take the time to test a particular brand of 10mm ammo, and then do the 'happy dance' over the resulting fps/fpe numbers, just be sure you're telling us about
real 10mm ammo, not some .40-level junk that merely masquerades as a 10mm load. For any self-respecting 10mm-user, that's a waste of money, frankly ... and calling it a "bear load" - with all that implies - is embarrassing, misleading, and, possibly, dangerous. (Yea, I know that's what HSM calls it, not you.)
agtman you must be looking for nuclear loads Not defending HSM, just reporting on it the Bear Load isn't nuclear but it isn't 40S&W either, at the average velocity it delivers 625ft/lbs full loads start about 600ft/lbs.
Huh?
Sounds like fuzzy math ... Better check it again.
By the way, the 10mm standard of "200gns @ 1200fps" was the original standard established by Norma when the cartridge was introduced in 1983. That was
waaay back in the day when handgun propellants were limited compared to the more recent diversity of propellants that ammo-makers can access now, not to mention the development of special hybrid powders (as noted below about DT).
Another factor is, we've had
35 years of experience with the 10mm cartridge. So what was once considered a "maxed-out" full-throttle load, which varies with the bullet-weight in question, is different now. Using a 200gn bullet, the so-called "nuclear range" is now right on
1300fps.
Heavy hardcast slugs (running 200gns, 210gns, 220gns , and a few 230gns) have also been developed for specific hunting applications, most launching at or beyond 1200fps MV. Better bullets (or boolits), and better powders to give you higher velocity with less pressure. Good, and good.
Koda94 the HSM "bear Load" is listed on their website as 481ft lbs at the muzzle. Its not anywhere close to a real 10mm load. * * *
Koda94 is right. ... MRG's stated "average" velocity of 1041fps for the HSM 200gn 10mm load yields an average 481fpe. That's a "10mm" load in name only, being watered down to anemic .40-level specs. Heck, DT's
.40S&W 200gn XTP-HP load, using McNett's proprietary hybrid propellants, averages
1050fps from real-world guns (.40 Glocks).
