To my way of thinking the Weaver T-36 without the magnifier is perfect at 25 yards...
At AGBR matches, I've had other shooters hunker down behind my gun and look through the T-36 and comment how perfect it is. I find the 24X is very usable but the 36X is much nicer to use and I do agree that more power than 36X would be overkill. However the T-36 works so well for AGBR I've just bought a second for my new AGBR gun which you can see in a picture in post #33 of my thread, "Rifle for for Airgun Benchrest?" that shows my new gun with the T-36 on it...
However, I have to ask, What is wrong with the Swift 8X-32X, if you have it why not use it?
Happy shooting,
Mitch & Shadow...
