We last looked at the .22-caliber Talon SS on June 13, when I told you that I had mistakenly shot the rifle with a standard air tank instead of a Micro-Meter tank in the previous test. I retested the rifle with an AirForce Micro-Meter air tank and the standard 12-inch barrel. Today, I want to finish the test with the optional 24-inch barrel.
You’ll recall in Part 8 that I shot the rifle 380 times on a single fill of the Micro-Meter tank. Today, we’ll see what difference, if any, we get from the 24-inch barrel. The only pellet used in this test was the .22-caliber Crosman Premier pellet.
Let’s begin — shots 1 to 10
The tank is filled to 3,000 psi and shooting starts. The power wheel is set as low as it will go. The first three shots go 429, 536 and 667 f.p.s., respectively. Shot four goes 726 f.p.s. and the rifle is stable from that point on. The first three shots were needed to wake up the valve. Discounting the first three shots, the string averaged 727 f.p.s. and ranged from 725 to 732 f.p.s., a spread of 7 f.p.s. The average energy was 16.79 foot-pounds; and yes, I’m aware that a Micro-Meter tank isn’t supposed to be that powerful. But we’re seeing the effect of doubling the barrel length in a precharged gun, and it’s dramatic!
Because of the large number of shots I expect to get from the tank, I then shot 30 shots without a pellet. I’ll call these blank shots.
Shots 41 to 50
This string averaged 715 f.p.s. and ranged from 711 to 718 f.p.s, so another 7 foot-second spread. The average energy was 16.24 foot-pounds. Then another 30 blanks were fired.
Shots 81 to 90
I shot this string on the highest power setting the gun has — just to see if there was any difference. There wasn’t. The average was 705 f.p.s. and the range went from 702 to 709 f.p.s. Another 7 foot-second spread. The energy was 15.79 foot-pounds. Then another 30 blanks were fired.
Shots 121 to 130
The gun was set back to the lowest power setting and remained there for the rest of this test. The average was 675 f.p.s., and the range went from 668 to 679 f.p.s. the spread was 11 f.p.s. The average energy was 14.47 foot-pounds. Then 30 more blanks were fired.
Shots 161 to 170
The average was 658 f.p.s., and the string ranged from 654 to 662 f.p.s. — a spread of 8 f.p.s. The average energy was 14.17 foot-pounds. Then 30 more blanks were fired.
Shots 201 to 210
The average was 641 f.p.s., and the range was 637 to 653 f.p.s. This string had a 16 foot-second spread. The average energy was 13.05 foot-pounds. Following this, 30 more shots without pellets were fired.
Shots 241 to 250
The average for this string was 618 f.p.s., and the string ranged from 613 to 621 f.p.s. So, a spread of 8 f.p.s. The average energy was 12.13 foot-pounds. Following this, 30 more blanks were fired.
Shots 281 to 290
This string averaged 594 f.p.s. and ranged from 581 to 601. So a 20 f.p.s. spread. The average energy was 11.21 foot-pounds. Then 30 more blank shots were fired.
Shots 321 to 330
The average was 561 and ranged from 553 to 568, and the spread was 15 f.p.s. The average energy was 10 foot-pounds. After this, 30 more shots were fired without pellets.
Shots 361 to 370
The average was 539 f.p.s., and the string ranged from 534 to 545. A spread of 12 f.p.s. was observed. The average energy was 9.23 foot-pounds. Another 30 blanks were fired.
Shots 400 to 410
Now we’re in uncharted territory. The gun is giving me over 400 good shots on a single fill. Clearly, the 24-inch barrel is a real boon to the performance of the MM tank. This string averaged 519 f.p.s. and ranged from 514 to 527 f.p.s. A spread of 13 f.p.s. The average energy was 8.56 foot-pounds. After this, 30 more blanks were fired.
Shots 441 to 450
The average was 497 f.p.s. and the string ranged from 489 to 504 f.p.s., for a total spread of 15 f.p.s. The average energy was 7.85 foot-pounds.
I could have continued to shoot the gun for many more shots, but I stopped at this point for a reason. After 450 shots have been fired, the Talon SS is still launching pellets slightly faster than my Diana model 27 breakbarrel. If that’s enough power for me, then this gun certainly gives all that and more. And I can’t think of another time when I shot 450 shots, unless it was for a test like this one.
The 24-inch barrel added significant performance
We all know that barrel length is important to a PCP, and this test makes that very clear. The 12-inch barrel gave 380 shots that ended up in the high 300 f.p.s. range. We’re still 200 f.p.s. faster than that after 450 shots have been fired! I think that establishes the Micro-Meter air tank as the champion of PCPs with the 24-inch barrel is installed.
In this series, we’ve looked at the Talon SS as it comes from the factory and with various modifications. The one we haven’t tried yet is the CO2 adapter, so that’s next. I’ll leave the 24-inch barrel installed since that’s the way I shoot the rifle all the time now, but I’ll test both velocity and accuracy with CO2 for you.
