depends on the distance you plan on shooting to. SSTs are suppose to be accurate at longer ranges.. Are they in your gun? I have both SST and 3" Lightfield Commanders IDS in 12 gauge 870. both shoot well to 100 yrds. I haven't practiced any further than 100 yrds, and mostly shoot to 50 yrds.. I'm partial to Lightfield Commanders because of the holes they leave and my group with them at 50 yrds. My cousin likes Remington Copper Solids in his 870, because he shoots so well with them, and is recoil sensitive with 3" Lightfields. Again, this is 12 not 20 gauge.
If I had the funds, I would get a 20 guage 870 and load with Lightfields if it shot them OK. I like slower larger cal. to faster smaller cal... just from my own exp.
Oops,,, I'm in the TC area..
If I had the funds, I would get a 20 guage Encore and load with Lightfields if it shot them OK.
You also said your dealer ordered you some SST's... I hope you get them before next hunting season. If you don't have them in your hand, you may wanna call Cabelas and see if they have a few boxes in stock and buy them to make sure you get them... My local retailer put in a large order last yr at a gun show with the Hornady Rep, and never got them till Spring. Nobody around here had em. when I went there a few weeks ago, they had only 4 boxes left,and that was all they were going to have this yr. and I grabbed them all.
I also see you are a bow hunter and if your hunting shotgun like bow hunting, out of a treestand and ranges not longer than 40yrds, then save your money and find a good cheap slug that will group.
My cousin and I see so many shotgunners (including ourselves) that are disgusted with the groupings of some very expensive ammo...
good luck this season.
