This thread once again differentiates between the bench shooter mentality/requirements and the hunter/plinker mentality/requirements. The standard recommendation of the plinker sect is a 4X, 2-7X, 3-9X... and they scoff at more magnification. Whereas the bench shooter, who chases one's and two's already knows that plinking scopes won't cut it.
Personally, I am more of a hunter, with rifles wearing 2-7X, 3-9X and 4-12X scopes... my two bench rigs wear 24X and 36X scopes... the difference between the two concepts is readily apparent when you settle your eye behind the scope... and when you walk up to the target.
The difference being that a lower power scope can be used to hunt OR shoot very decent groups from the bench, whereas a 36X is superior for bench shooting but tits-on-a-bull useless for anything else.
If you have a dedicated bench gun 36X is just logical. If you're just runnin' what ya brung, your usual real world setup makes more sense.
We are talking about "small" groups... not this "I shot a 1/2" or 1" group at 50 yards with my 4X scope you don't need nuddin' else..."
The majority of posts in this thread do not reflect that. If the title had been lengthened with "to shoot benchrest competitions", then it would have been more geared toward that. Most people are just posting what they used for the CGN 50m challenge, or use for 50m in general, as the title was not specific to serious bench shooting.
A question I have asked in the past is "How much magnification do I need on my .22LR for shooting at 50 yards from the bench?" A lot of shooters are shaped by their hunting experience, which in my part of the country usually doesn't involve long distance shooting and where a 2-7 or 3-9 does the job.
But how much is needed to see and hit a target at 50 yards from the bench with a .22LR?
Both my 22 and my 17 got into the .200's with a 3-9 @ 50 meters. While that won't win any competitions, it's good enough for the casual bench shooting I do for fun.
Best shooters I've encountered did not use magnification or a scope at all. A decent diopter sight and they were putting 5 rounds on 50 meters into 8-10 mm all day long. IMO those bowling pins on a .22 look hilarious.
The lesser the skill the higher the magnification!
