What would you consider a good group shooting?

[8mm RUM]

​I have a new style ( 2012) Blackhawk 45 colt 5 1/2" barrel.
I put an inexpensive Holographic red dot on it and Hogue grips.
I cast some 303 gr hard cast bullets with a copper gas check and powder coat sized to .452 and Winchester w-296 someplace close to 1200 fps.
I'm getting about 2 to 2.5" at 30 yards.
I shot off my hunting sticks I use with my rifle, sitting down.
At 15 yards I'm center punching clay pigeons with little to no aim point adjustments, up or down.
I have only shot 75 shells so far through the gun, will it improve like a rifle?
I plan to shoot deer with it at some point but would sight it into 100 yards for that.
For now, it's steel, gophers, and coyotes. What do you think I can expect out at 100 yards?

3" - 4". Maybe less but not more.

short bbl and a dot vs a scope is gonna be tuff at 100.....but min of deer sure

When I was shooting PPC with my 6” S&W M14 target Masterpiece I’d get 1-1/2” offhand at 25 yards slow fire. I’m happy with 2-1/2” now (older eyes w/Verilux lenses and a bit shakier).

I can do 3” at 15 yards with my S&W M&P 9 Shield compact (iron sights). My EDC.

Now, with my 10” Contender and a 2X Leupold in .22lR I can do 1” at 50 yards.

All very different pistols with very different uses.

3" - 4". Maybe less but not more.

I'd say at very best, although I'd guess a little bigger assuming the same setup that you used to get 2" to 3.5" at 30 yards.
