10 quality posts, reponding to your own post twice won't count. I've found that using a barrel band may cause poi shift with the expansion of the bottle if you live in hot climates. I run all my guns without one. Even my impact withh a 700cc bottle.
Most of the Olympic quality rifles are constructed in a relatively solid manner. Also, it's really difficult to compare the need (or not) for a band in a general purpose rifle and a dedicated match rifle. Whether 10M, three-position or BR, the shooter has the opportunity to check the zero of the rifle before shooting for score, and the rifle isn't banged around during the match. And in high level competition, whether the consideration is for a barrel band, moderator, magazine, etc., there is no need to introduce an unneeded variable, regardless of how small the risk of negative effect.
as far as the post count,,, i thought it would make a difference in posting in classified section. looks like its disabled.
I dare say that you have a very specific and different scenario. Due to shooting at 35 caliber round out of a not study .35 barrel and that length certainly didn't help. I tried using the Huma air tensioner/rail extender and and the gun looked great but anytime I wanted to shoot the gun for the first time. In the first few shots, the rounds would go like 6 inches to either the left or the right. And it never made sense.
