I bought the largest poly double case at Dunhams , it just fit in w/ a large scope .Just picked up the Avenger Bullpup and need suggestions on cases. Using a 3x9x40 scope . Any help would be appreciated.
The barrel lands are.44 but the grooves are.45. That's the way they Catarized calibers back then.I've read several different accounts of the same gun and I'm wondering if like black powder rifles they were made in different calibers.. I have read 36,42,44&46.. possibly the 44,45&46 are just different ways to measure the same gun.. since my black powder 44 actually has a 45 barrel and uses .454 lead balls..sort of how now big bore airguns are not a common size, you get the airforce texan and it's larger than the similar caliber as the Korean ones..I tend to think that it makes sense to be in a similar caliber as the black powder guns in the time.. I've shot black powder 36 caliber squirrel rifle and 44/45 black powder revolver and 50 caliber black powder rifle.. as far as the rifle went I really shot the 36 caliber more and it was quite accurate.. I also loved the double set trigger.. anyone who has shot double set trigger would understand that.. it's a feature I wish was available on airguns as well.

HW95L | 26 Bore Diameter Piston Seal Size (mm) | 85 Piston Stroke (mm) | 45.13 Piston Swept Volume (cc) | 3x15 Transfer Port x Length (mm) | 0.106 Transfer Port Volume (cc) | 426:1 SCR | 254 Piston Weight in Grams (g) |
FPS = Feet Per Second, MPS = Meters Per Second, FPE = Foot Pounds of Energy. | |||||||
To convert to Joules multiply FPE by 1.3558, Joules to FPE multiply by .7376 | |||||||
To convert MPS to FPS, MPS x 3.2808399 = FPS . | |||||||
To convert FPS to MPS, FPS x .3048 = MPS. | |||||||
FPE Formula is Pellet weight (gr) x FPS x FPS divided by 450240 or 450436.7. | |||||||
450240 is 2 x velocity of gravity x 7000, (2 x 32.16 x 7000 = 450240) | |||||||
450436.7 is 2 x velocity of gravity x 7000, (2 x 32.17405 x 7000 = 450436.7) | |||||||
The constant 450240 or 450436.7 depends on which value you use for the velocity of gravity. | |||||||
32.16 ft/s/s or 32.17405 ft/s/s. There are 7000 grains in one pound. | |||||||
The difference does not matter which ever constant is used for the FPE calculation. |
Thanks for the write-up. I think looking through window glass may mute some differences, but so does ambient lighting, light direction, 'target', etc. Doing a thorough scope review is not a trivial thing! I appreciate your honest approach in both testing and reporting. For testing IQ you can make targets with black bars which are spaced progressively closer. At some point the lower IQ scope will be unable to resolve the separation between lines. This is quick and (relatively) easy, and you can do it at varying ranges just by scaling the images. Just try to test all scopes at the same time to eliminate the confounding influences of lighting.
In my opinion, and I have ZERO experience with the Ares, the reason to go with Nightforce is the accuracy over large adjustments, and of course durability. Of course, durability is something we mostly take someone else's word on, as I (and I suspect most) am not willing to drop my scopes nor throw them against the wall. Precise adjustment though is readily tested - even more easily with airguns. Do a search for "scope box test" if you don't know what I'm talking about, then do a box test that is ~80% of the bounds of the scope adjustment range. I certainly can't claim to have tested more than a tiny portion of what's available (and again, nothing from Ares) but the NF scopes have been consistent winners in this regard in my testing.
