For the first time I added a 1/16" nylon washer to my comb to shoot mid yardage. I was hoping to have the same target aim point as I would at the 16 and it seems to work. I feel this way you don't have to mentally change your game between singles and handicap.
You don't need anymore than what you have. Maybe some barrel work and proper choking- .026 to .032 restriction is adequate for 16 and caps. None of the shooters that I shoot with change anything from shooting singles to the 27 yd line.
I know a guy that has two Kolars with PFS stocks. One is painted grey and one is painted black. One is shot at 16 yds., and the other is shot for yardage. I personally would like a different gun for handicap. I would want it to shoot flatter though. Figure the farther back you go the higher the shot will go above your sight plane, compared to 16 yd. targets. The key is to get a gun that shoots the same sight plane for both. The only way to do so is to shoot a flatter gun at 16 yds. You could adjust your sight plane at handicap. Float the bird more. Jon
I did for a while...used a BT99Plus for singles and a 32" Citori Plus for long yardage ..my only reason is the O/U was a noticebly heavier which both slowed and smoothed my swing which let me be a bit more precise when the rocks got far and tiny...but I dont any more
If you are shooting the same load for both, then some equipment "change" is generally warranted...higher comb to raise the poi, usually, and increase the choke constriction. If you will increase the velocity of the load and increase the choke constriction as you move backwards, it is very likely that you can remain with the same set-up for most applications. But if you've got the hots for a new something, by all means go fot it! It is a very expensive "fix" to something that isn't broken and will introduce additional variables into your shooting equation. By the way, are you shooting competetively yet, or are you just getting into it? Talk to several of the better 27-yard shooters at your club and see what they say. Or go to a registered shoot and see what the best shooters do. IMHO, if you are serious about it, you'll find a way to stick with the same gun for both to reduce the variables in a game that demands near-perfection.
