Seismic Quakemaker +M ammo...

Here you go - for those who believe momentum and "knock-down power" are relevant things in SD ammo:

Still, it has an interesting case similar in design to some 50-cal ammo I've seen - 2-part case that screws together.

Well, interesting. Picking up cases with a magnet is nice.

Random thoughts:

I tend to lean towards heavier ammo, but I wonder what makes this heavier than others?

Once the two-part case goes together, can it inadvertently come apart? That would be unhelpful.

And of course...price? Their website is very minimal, about three pages.

The SHOT show is in progress, I wonder if anyone will get to shoot it there?

Need more info and data to evaluate. Energy is proportional to velocity squared so need to see numbers and some sort of ballistic gel testing results (recognizing the inherent deficiencies in gel testing but still interesting none the less IMHO).

Do these come in APFSDS (Armor Piercing Fin Stabilized Discarding Sabot)?

I'm no physics expert, but I have my doubts about their claim of lower recoil due to slower burning powder. It will still require the same force to propel the bullet down the barrel. If it is too slow burning, it will be more like a flintlock, in that there is a delay between firing pin strike, and combustion. Which will not reduce the felt recoil, but slow down follow up shots. If I wanted heavier bullets, at lower speeds, I would switch from 9mm to 45 acp. I can't see this as much more than a very expensive gimmick. JMHO

I suspect they have a bridge they want to sell me along with the ammo.......

Ohhh in 45-70 for when the home invader tries to hide behind a brick wall!

That would be right up your alley :mrgreen:

I'm going to say the recoil impulse is similar to the difference between .45FMJ and .40S&W, and I'm not a huge fan of either OEM load. Against moderately insulated human beings, the mid-range (124-135 grain) loads, running 1200-1300 fps generally produce the most consistent aggression-stops, with the most hits on-target.

If you live in the upper midwest/northern states, a bit more weight and a bit more velocity may help deal with winter coats. In southern locations, lighter, faster bullets will suffice (110-120grain, 1200fps+), though the 124-135 gives a bit more "oomph!" against mid-weight barriers (auto glass, sheetrock, etc..)

I've tried the spectrum. I keep coming back to what I can apply the most of, the fastest. Big-n-slow, uber-snappy hi-vel, name-your-miracle-bullet, etc., hasn't been there yet.

You don't normally see 9mm being offered above 147 gr or 45 ACP above 230 gr.

This sounds like a lot of hat and maybe a little cattle.

SAAMI defines +P ammo.
+P+ is NOT approved per SAAMI.

Has SAAMI actually defined "+M" and approved it?

If not, do you want to use it in your firearm?

I would if I didn't carry a .40 and performance tests showed it wasn't a gimmick. It will be hard to justify over HST or Gold Dots but heavier bullets usually penetrate deeper.

I would be curious to see how they perform in a carbine with extra velocity.

"I can't see this as much more than a very expensive gimmick."

Yep, that was my first impression. And so expensive that most people would not even shoot enough of it to know if it is reliable in their gun. Or NOT.

Yes I'd like to know the specific weight but I was actually wonder what material they use to make it heaver? Depleted Uranium? :mrgreen:

I'm going to guess "some will". People load non-standard non-SAAMI cartridges all the time, with different weight bullets and more/less/different powder etc.

Would like to see the actual ballistics and a full-up FBI protocol test.

There are so many configurations of ammo available today it takes some chutzpah to jump in to the market with a new offering. I'm will to wait and see if these guys really came up with sumpin' or not.
