A mechanical rear rest by itself is not gonna take a mid pack shooter to the top of the page. I’ve been playing with one and shoot the same off a Protector bag OR the old HG rest that simply contains a 2” front bag.
I’ve spent untold monies making my LG’s weigh under 17#. That’s been the weight from the get go, everyone in LR BR has adhered to it. IF by some freak chance a F class guy wants to shoot for groups with a 22# gun, they can do it… in HG. Get their feet wet, if they like it, spin up a tapered barrel and shoot both classes the next time.
Right now the Tac IS sort of the unlimited class that a lot of us want to see. Experimenting with very few rules to allow pushing the envelope. Some ranges are sorting out the guys with bipods and keeping track of the “true tac” sub category within the class. To me, this is best case scenario for now anyway. As to the weight limit in Tac… some PRS guys are shooting rifles way over 22#. The less rules, the more inclusive to a point. In my opinion, you can’t have say 5 different classes. You’d never get done shooting in one day so the sub classes that some are recognizing is great.
My opinion here and why I shoot BR. Benchrest is the pinnacle of rifle accuracy. There’s a lot of factors that contribute to the inaccuracy of a rifle system and through Benchrest techniques and practices we try to minimize those factors. This isn’t offhand, sling or any other discipline where any wobble is desirable. We’re out here trying to shoot the smallest groups possible. Someone is always going to shoot the smallest, maybe on a given day it’s you and the next maybe it isn’t. My advice is to compete against yourself and try to do better each time out because if you’re comparing yourself to only the winner every time, more often than not you’re going to be miserably disappointed.
To be at the top of this game takes good equipment but what so many fail to ever realize is the time commitment it takes to get to the top let alone stay there. It’s too easy to blame lack of ability and commitment on money.
