20 ga for grouse....

[Curly]

Are you talking ruffed grouse or blues?  For ruffed, 7.5 or 6's.  If blues are in the mix then 6's or 5's.

I've used 5, 6, 71/2 with my 12 gauge. I've gone back and forth with my choke based on what types of experiences I'm having, or what kinda grouse we're after - what the trends are for my outings. Are they usually flushing a good distance away? Or are they scaring the B-JAYSIS    outta me because they're holding right until I'm pert near stepping on them? It seems like which ever choke I have in - mod or full - the exact opposite is the one I'll be needing for that day...

Head shoot them always.
 
#6 shot size.

I shoot a 28 Ga S/S, and have found the Fiochi nickle plated shot to do very good kills. Copper plate is good, but nickle is better.

The 28 gauge seems like it would be the perfect grouse gun. I may have to get one someday.

My son hunts them with a H&R/NEF® 28ga  Single Shot Mod choked w/7½ shot. I use a Remington® SPR220 (Baikal® IZH-43) 20ga SxS. I put Imp Cyl & Mod chokes in for grouse and use #6 & 7½ shot. For the big Blue Grouse and Spruce Grouse, chokes are the same but w/#4 & 5 shot.

Me too! I would love to get one in the future....

6's and 4's would be my choice.

 

I have had them lock their wings and glide away with a good hit of #6s from my 20 full choke. they don't seem to do that with a load of 4s in them... must be too heavy to fly with

Grouse are not hard birds to bring down.  a 1 oz load of 6's or 7.5's is plenty, as long as you do your part.  If all I had was a full choke 20, I would give polywad a call and buy a box of spreader loads, to turn your full choke into a modified.  If you do manage to connect at close range with a full choke, that is not a bird I'd want to eat.  Open up that pattern: you'll kill a lot more birds.

...or don't shoot em close in with that full choke...let em get out a bit before you pull the trigger...
