When you get used to the release, it is a non-issue. Carry it with barrel tilted up or down until ready to shoot if you are in a stalk, the gravity does the rest.
I have an Ultra in a 450 & because of the weight in the stock & I added a slip-on pad to the buttstock on to of the factory pad, the recoil is fine. The add-on pad is an option that some may not want, but I have long arms, which makes it work good. With these 2 items I see no need in abrake. I will never use one on a 450, but if I did, I would not want to cut the barrel & then add a brake, as the increased muzzel blast would be too close to my face, therefore unneccessary added noise.
Cutting the barrel will hurt the velocity, as Mr. Weiss said. I do not understand cutting the barrel, as the gun already has a 22" barrel &
because it is a single shot, the gun is about the same length as a 18" bolt gun as is, how short does it have to be? I hunt in some thick crap & I just don't see it, but to each his own.
