36x is not too much scope for 50y rimfire BR matches. I use a 36x Sightron for ARA matches on my Remington and it works great. I have friends who go much higher on magnification as high as 50x and 60x. I have a bias here. I think that as long as you can see the tgt clearly, then more magnification is not really a benefit and could?? sometimes be a detriment. The rifle does not know what power the scope is and it shoots the same either way. So the scope is merely an aiming tool. I have a 40x optic that is too much scope for many cases. It is easy to loose track of where you are on the tgt and makes it easier to make a mistake and fail to engage a tgt. That is not a big deal and is easy to avoid with care but 36x is enough for me. For some of my old classic Win 52's I have 24x, 20x and 10x scopes mounted. The 10x is a very clear old Fecker and is not really much of a handicap. With the 10x mounted I was shooting 248's and 249's. I replaced it with a 20x Unertl and was shooting 250/19x in the first outing so it did make a small improvement on what was already a great old rifle. The 20x is plenty of magnification for 50y BR. Other factors like wind and ammo variance become the more important variables at that point.
I shoot .22 bench rest on the USBR target (AKA the green monster) with a 0.108 10 ring and need all the magnification I can get. With a 42x scope I can move to each side of the 10 ring but any smaller adjustment needed and I can not see the adjustment.
Thanks for the feedback, guys!
