Changing scopes on a double

Well, that left crown could use some touch-up for cosmetics, even if not affecting accuracy.
No Sabatti-Technique re-regulation though.
I would rather use a steel ball bearing of about 1-inch diameter or bigger for grip in a hand vise, some JB Paste and elbow grease.
I hear someone up north routinely turns rifles into smoothbores with JB paste.
Ought to work on a crown ding.

I broke a rib and have not shot anything lately.
Will shoot with the 20-ounce scope and see how much difference it makes with same load,
and post the evidence.
Then I am reverting to a lighter scope and re-regulating.
Yes, the Monster scope on the 6.5# gun is ridiculous.

Quick KarlHow did you break a rib, ole stranger?
Falling across a log.
I am giving up my dream of becoming a lumberjack ...

Load the roundball ammo in RMC 2-5/8" brass only: Always uniform.
Also easily predictable pressures from QuickLOAD.
Also requires only a foam wad that is less likely to kill a chronograph.
Use whatever sight and just make the balls go faster until they shoot parallel instead of diverged.
Or, settle for a modest load and do the re-regulation.
Non-uniformity of factory loaded sabots is the bugaboo here.
Making handloads with plastic hulls and roundballs is also quite tedious, to get uniform with a roll crimp.
Heavy RMC brass will be much easier to get uniform.
A uniform load is a must for regulation.
That is a fact.

Quick KarlWell, a broken rib can be a real pain in the side.
I hope you get well soon!
The "pound and a half" of scope and rings did not help.
Going from a half pound to a pound helped more than the last step up to 1.5 pound sights:
I finally risked a couple of shots over the chronograph and was shocked to see how slow my 330-grain 20-bore balls were going.
Only averaged about 1380 fps, but there was only 3 fps difference between the only two shots dared.
No chronograph killed.
It will be easy to make the barrels converge with increased velocity,
but the vertical spread is going to need Re-Regulation!
I am going to stick to RMC brass and round balls for the ultimate in consistency, and much higher velocity is possible with that combo.
Will consult

shootawhey for handtool tips on the re-regulation.
