Subbed
Since you brought up the subject...
Reading comprehension may not be your strong point, so I'll make it explicit: the whole point of the shotgun angle was that a poster was unclear about what constituted barrel length. You may recall they thought it was related to the length of rifling. It wasn't.
Carry on.
Another interested person here. Gunner or pencil profile with brake (not FH) preferred.
yup pencil profile with integrated brake. This would be ideal.
If they were made with several barrel profiles and brake/hider combinations and they had competitive pricing, I think they'd become the non-restricted standard in this country. I'm also curious how a 17" barrel would do against the 16's and 18's ballistically.
You only lose about 20 to 50 fps for each inch (in these longer lengths, not for shorties)
Pretty negligible
A 16" is about 3178 fps using 55g
To 3205 at 18.5"
That's only about 25 fps
These are approximate numbers as every rifle and barrel and cartridge is a little different but the loss will be comparable pretty much
