I've never heard of anyone using .40 S&W for match bullseye shooting, but I'm sure someone has tried it. Anyone have any recommendations for an accuracy load? I'll be shooting it out of an M&P fullsize if that helps.

The caliber is not used in Bullseye shooting as far as I know.
The guns chambered in it are not SWC friendly, as the 9mm size guns adopted to the .40 do not feed .40 SWC bullets well, if at all.
And SWC bullets cut clean holes in Bullseye target scoring rings.
And that is often the deciding factor between winning and loosing a Bullseye match.
Were I trying for an accurate load?
I'd probably try a conventional 180 grain truncated cone jacketed bullet with a mild charge that just cycled the action.

I've found that 3" groups at 25 yards are do-able with the right barrel and bullet. For accuracy I would start with the Hornady 180 HAP and Universal powder.
Does the M&P have land & groove rifling? If so try the Rainier 165 flat point. It shot great in my KKM 10mm to .40 conversion barrel and a P226, but plated .40's don't do very well in stock Glock polygonal barrels IME.

U mean like this?
Glock 24 (factory bbl)
This load matches the 230 FMJ-Bullseye/231/Clays/whatever for accuracy out of a match grade 1911.

918v, very nice. Mind sharing your load?

I have two:
Armscor 165 FMJ FP
155gr Gold Dot
I tried 180s but they not as accurate.
I tried other primers, but groups open up.
I tried other OALs but groups increase in size.
It's hard to get a factory Glock to shoot good. I read somewhere on the Internet that 165s are optimal for the 1-16" twist rate of the .40 S&W.

Thanks, I'll give those a try.

Let us know. I think TG is the more accurate powder with a variety of bullets. 231 is very load specific.

Nice shooting 918v.
Here's my best effort at 25 yards with a KKM converted G-29 (2 hand standing).
Rainier 165 flat point over Universal.
