I have the MACR.I sent a cart to rsterene to get his expert eyes on it.I can tell you a lot of real world details on the MAC style carts.Is it a fun Gun? Yes!! It's not what we would call high power but it has that fun factor and is so different you gotta love it.Would I buy one as a hunting Gun?No. Bottom line is it just does not do what is claimed and my numbers back that up.Now if you stay about 50 yards? It's a shooter.I'd look at a better Gun like the Slayer to really reach out.
I did some careful measuring of the MACR Cartridge capacity, and even through the outer housing holds 11 cc, by the time you subtract the volume of all the parts inside, the actual volume of HPA inside is only 8 cc.... The transfer tube that runs through the middle of the cartridge has a hole 2.5" long that the air must pass through to get to the pellet that is only 0.165" in diameter.... so it's like having a transfer port of that length and diameter between the reservoir/valve and the pellet.... That is about the diameter you would expect in a medium performing .22 cal pellet rifle.... so even though you can use up to 4500 psi, I think you will find the gun underpowered in anything over .257 cal.... and even in that caliber not a stunning performer.... IMO just not enough air, and way too small porting, for a Big Bore....Bob
140 FPE in what caliber?.... The best Jeff got at 4000 psi in .357 was 647 fps with a 98 gr. bullet, which works out to only 91 FPE.... At 4500 psi, that would extrapolate to about 102 FPE.... Using a much heavier bullet, say 140 gr. would likely up the FPE a bit.... but unless they have increased the air capacity, or the port diameter, (or barrel length), I have my doubts about that claim....Bob
The guy in Mexico is Alvaro. He showed up at EBR with that gun in 2015. It is .30 pellet shooting 44 gr pellets. It has a 38" barrel to get the speed needed that a normal gun does with a 20" barrel.The gun is a good conversation piece is about it. They missed the performance part by a long ways.
FPE is pretty much in direct proportion to pressure, so 4500 psi should be 50% more FPE than 3000 psi.... However, FPE also depends on barrel length, so a 14" barrel would drastically reduce the power compared to the 28" barrel on the MACR that Jeff tested just a few days ago.... Since the cartridge volume is so small, the usual rule of thumb for maximum power that half the barrel length would result in half the FPE doesn't apply.... but taking the test that Jeff did and cutting the barrel length in half should reduce the best FPE he got in .357 cal, which was 91 FPE at 4000 psi, to just 65 FPE.... and dropping the pressure down to 3000 psi should drop that down to just 52 FPE, not 100.... Something doesn't add up, if their factory data is so much different than the results Jeff got....PS - I just tried to listen to the promotional video on the Baracuda, and the audio quality is terrible.... I gave up because I couldn't understand any of the important information, even the caliber was almost impossible to understand.... Bob
