I have a Winchester 1300 speedpump, currently when I am shooting shot I use an extra full choke. when I shoot slugs I use a cylinder choke. my question is, is there a choke that will accurately fire both shot and slugs? I hunt with my shotgun often, and when I am going after boar or other thick hide animals I would like to be able to alternate load my shotgun without having to worry about which choke is in the barrel.

When shooting slugs you don't want to use anything smaller than a Cylinder Bore. If you do you have the potential to blow out the choke. Getting an over under and using slugs in one barrel and shot in the other is probably your best bet. With what you have though, stick with the Cylinder Bore.

your winchester may vary, but for mossberg recommends improved cylinder for slugs.

what range are you shooting shot and what is your target?

 

[ShotgunPro]

Many of the guys who shoot 3 Gun routinely use light modified with slugs. Lots also use improved cylinder. Either choke would be slightly better than cylinder for shot.

Try a couple different slugs through a couple different chokes on a pattern board or target and see what you get.

However, as always, the risk is yours so do whatever you are comfortable with.

Take care,
Dave

I put slugs through my Mossberg and Benelli using IC chokes, no problem.

looking at midwayusa, it looks like the majority of 12 gauge slugs they offer for reloading are .650" diameter.
12 gauge barrels are .729" an x-full choke is .689. Im sure you would get an over pressure from the wad trying to get thru, but the lead would pass through.

how well does the IC pattern buckshot?

Upper pattern was at ten feet.

Lower was at 50.

Load was Winchester Ranger Low Recoil 9pellet 00 (RA12005), shotgun was a Benelli M1S90 Tactical, 20" bbl.

And what it does with slugs at 50 feet:

Slugs were just cheap Federal 2 3/4"s; first 3 shots were slow fired offhand, 50'; second two were a double tap from low ready.
