    I looked at one myself. It;s been around a while. I couldn't find any good reviews on the Oly so I gave it up.

    Tim, do you always measure "power" by some numbers, in someones book of formulas?

    Have you ever looked at the specs for a 10mm coming out of a 16" barrel?

    There is some simple, figure it out in your head using common sense, kinda math that makes a person question your definition of "power"

    The 10mm with a 200 gn bullet has somewhere between 2,5 to well over 3x the weight depending on the bullet weight, the 10mm has a bit less that 2x the diameter, the only thing the .223 has is around one third more velocity depending on bullet weight, the heavier the bullet the lower the velocity gap,

    Again, if some other formula trips your trigger and makes you feel fuzzy, great. But if I had to drop a POed bear with one shot, or take a bet on which bullet wouid stop a deer at 100yds with a raking shot,I'm going with the 10mm.

    I can understand an AR15 in 9mm because 9mm is cheap to shoot. .40smith costs almost as much as 5.56, so that wouldn't be worth it... 10mm? Holy crap. It's like paying for a .308 and not getting it.

    If you cary a 10mm pistol I can understand that you want to stay with one caliber.
    Otherwise why would you want an expensive 2nd caliber like this?
    Also, if I would get something like this, I would register it as SBR and get it down to somewhere between 9-12".

    sorry...i guess the only formula I was using was the messes I had to clean up after in afghan, combined with the fact that 10mm is just a handgun round.

    Also, am I the only one that sees bad things coming from a straight blowback gun in 10mm?

    "Blowback 10mm" and "Olympic" are three things that should never occur in the same sentence.

    I'd rather have a .308 or 5.56mm AR. Failing that, a .450.

    The Tommy gun was based on just a handgun round, and in .45ACP at that, which is alot less powerful than the 10mm. I think a 10mm AR would make more sense than an AR in one of the .458 SOCOM or .50 Beowulf loads IMO. :dunno:

    There's a reason why armies don't issue Tommy Guns, or any pistol caliber submachineguns now days, the assault rifle is superior. The 10MM in a carbine is rediculous expensive to feed. Might as well be shooting $5 bills.

    You can't find any good reviews on Oly rifles because they suck. I got so tired of sending them back for repairs, that I just quit stocking them in the shop 15 years ago.

    Typical GT. Nobody owns one, yet they **** all over it.

    I own one that I pig hunt with. It's on my M16A2 lower. With Doubletap 200 gn, it stones pigs from over 100 yards. The upper operates fine with no issues and is accurate.

    I'm getting the barrel cut to 10" so I can use a can. So then I'll have a full auto 10mm suppressed. Yea, that must suck.

    I am not sure if this is a federal restriction, but at least in Maine hunting with a machine gun is a big no no.
    Beside, you can only hunt with a 5 round magazine.
    Just saying ....

    The 5.56mm round averages around 1200-ftlb(f) of kinetic energy at the muzzle.

    What's the 10mm with its velocity out of 16" barrel? If you have the velocity, it's simple to figure out: KE = 1/2(mass x velocity ^2). Gotta convert bullet weight from grain to poundage (5200-gr/lb ?).

    Or get the velocity of the 10mm out of a 16" barrel and go a website where all you have to do is plug in the velocity and weight, and the kinetic energy calculation magically appears.

    I don't know what the velocity of the 10mm is out of a 16" barrel, but whatever it is it has a long way to go in order to make 1200-ftlb(f) of kinetic energy at the muzzle.

    I may not have owned a 10mm upper, but I've owned an Olympic Arms XM-15 before. Never again.

    If you're a cowboy and have to carry all of your ammo in a saddlebag, including bullet casting and reloading equipment.

    If you don't carry portable reloading equipment, the 1-caliber thing doesn't make any sense at all. A handgun is carried for portability, at the expense of power/range. It's silly to then sacrifice the power and range in your long gun, jsut so you can reload them from the same box.

    I had a 10mm Oly about 10 years ago. It ran flawless.
