I have tried the Powerrbelt Areotips (245) with 2 (50grain) Pyrodex pellets. I've tried it with 3 pellets. I've tried it clean, a little dirty, and dirty. 6-8" groups at 100. Then I've tried it all over again with Hornady 245 SSTs. WQith 2 pellets and a kind of dirty barrel, I can get 3-4" groups. Is this normal, or is my friend's CVA that stays under 2" normal? He shoots three pellets of the same powder and the same Hornadys. At 250 yards he can keep them on a paper plate. Did he just get a lucky gun or should I keep trying other options? (I'm down $100 in bullits and powder this month.) My scope is good and all the scews are tight. It's not my bench technique, I'm doing good with the other guns. Any advice? Thanks

I'd ditch the pellets and buy a pound of Pyrodex RS and a package of winchester W209 primers.

With the sabots, Yours sounds like it may want a tighter sabot. Maybe try the 240-250gr XTP with a black short MMP-12 sabot and 100gr RS.

As for the Powerbelts, They seem to give Me the best accuracy with a lower grain powder charge, like 80gr. Also perform best with less powder.

I have had several Kodiaks and still have a pair, they all shoot-shot very well with 2 pellets 777 and 240 gr. deadcenter bullets, never seen the need for 3 pellet loads. Shooting one now with BH 209 and the little 200gr. XTP's black sabot and it shoots inch and a half at a 100.
Shot Powerbelts one season and after finding fragmented bullets in two deer I shot put them up.

Worked on a friends CVA that wouldn't shoot last week. He was using 3-Pyrodex Pellets & Powerbelts for a 6-8" group at 100 yards. I really cleaned barrel which was a mess, used 150G Pyrodex Select, a bore button,Powerbelts, Rem. Kleanbore Primers & shot 2" groups. I plan to take the barrel & use J-B to polish out as many rough spots as possible. I believe the barrel is capable of a bit less than 2" after all this work.

I have one and its topped off with a luepold scope and I shoot 2 triple 7 pellets with the new Hornady FPB bullet.And man all I can say is wow!She will shoot almost a one hole group at 60 yds! And easy to load,and it shoots good with a dirty or a clean barrel.I love my kodiak!

Update: (I'm the guy who started the thread)
I went back to the range with Pyrodex pellets. My first three shot group at 100 with three pellets (50 grains each) was the same as with the 777. (about 7"). I then tried two pellets and shot a group a little under two inches. Just to be sure, I shot aother group that was a touch over two. Yahoo!. I'm averaging 1790 fps. I would have liked a three pellet load to work to flatten the trajectory out (With a 150 zero I was ten inches low at 200 and 25 low at 250), but I'm happy and will be trying it in a week or two on a late hunt. Thanks for everyone's help.

With the .45 Kodiak Pro I found that I had better accuracy with 80grns of 777 pellets then I did with 100grns. Shooting 225grn Powerbelts. The 275grns are acceptable but not quite as tight.
