Just curious what your load was for this target?

You might want to try some 340 gr DC's. They shoot well in my Omega. Try them with 2 x 50 gr T7 pellets.

Might want to try some other 209 primers besides the Fed. 209a's. Those are about the hottest primer you can get for a shotgun. Don't think I would pay the price for the special ML primers though.
Looks as if you are on the right road though.

Lane - thanks for the tip on the SST's. I did shoot a 3 shot group with them on Saturday - 2 holes were touching, but the third was a good 4" away - might have been a flyer, so I didn't post the pic. Unfortunately, I didn't have time to stay and play around with the SST's more - maybe next time. Have you used them on deer? I've heard some mixed reports about the .45 cal SST's performance on deer, but nothing on the .40 cal.

Cayugad - I'm not sure I would have tried bedding the rifle if I hadn't gotten some pretty specific instructions from someone from this site that did the same thing to a very similar rifle. Also, I don't think I would have done it on an expensive gun, or if it was shooting well to begin with - if it ain't broke, don't fix it, right? It was fun to do though - I love learning how to do new things

HuntAway-

That group was with shot with this load:

200 grain 10mm XTP
MMP tan sabot
80 grains FFG 777
Reminton Kleenbore 209 primer

That was the worst I think I shot - prior to free-floating and bedding, I shot some better groups, but none that were acceptable in my book.

I like the Dead Centers, but I'm not sure if I'm going to keep shooting them because of the price.

Looks like free floating the barrel and bedding the stock worked out pretty darn good for you. Worked like a charm with that old X-150 i had. Now you'll just have to work up new loads.
