What Al didn't 'spell out': @ 6X, the (S-Tac3-16) reticle would subtend 0.625". Especially for 'old' eyes, that would probably be quite manageable. Albeit with larger reticle and click values, numerous vari-X scope options are available.
Two years ago, upon arriving home from the NBRSA Score nationals, I looked into the potential vari-X scope options, I had to 'eat crow' - there were/are far more than I have kept up with. I was disappointed that the [vast] majority voted against accommodating increasing the weight to 10.5 Lb.
In the past, for Hunter Class, I have used up to 1.0 MOA Dot reticle successfully, including garnering my sole 100 Yd. NBRSA National Championship via a 250-16X score.
The large dot is actually a decent hold-off indicator: 'measuring' (visualizing) seems intuitive: center the dot, use the hold-off edge to gauge & reduced gap between that edge and the inside of the red-rings.
Now, with somewhat older eyes, that may be a much easier reticle.

Re-adapting to relatively crude 1/'4" click adjustment would be 'harder to swallow'. My old 1.0" Dot 6X Hunter scope does have decent 1/8Th MOA clicks.
The BIG fear of the variable-X scopes, seems to revolve around possible cheating - but
variable-X scopes, "set and taped" at 6X have been legal since I began shooting NBRSA registered Hunter Class
tournaments in 1977. In today's world, setting & taping would be easily enforceable using a tamper-proof tape, applied at weigh-in.
Breaking/activating the tape would result in disqualification: period.
The potential down-side would be making certain that I don't mess with your scope!

A D-Q or two, & people would, "get the drift" pronto. BUT, would THAT (any variety of tampering) occur?
I could live, easily and happily, with a weight increase, accommodating many more of the contemporary optics, which could bring more bodies back the the Hunter Class. In the past, MUCH more radical changes have been made - and with little/no discussion/voting - my biggest gripe was, following
1987, opting for the current EASIER two hundred yard target . . . a WAY bigger deal than allowing another 1/2Lb. of mass.
When it comes to magnification, I will staunchly stand for and vote for maintaining the 6X scope & 2.25" fore-end width rules, which are THE salient features separating the Hunter Class from the Varmint [for score] Class. If we aren't growing, we're dying . . .
