[quote]ORIGINAL: Treetopflyer

I went through much the same thing. Here's what I learned:
[ul][*]My SS/Laminated Omega does not like powerbelts, regardless of bullet weight or amount of powder or number of pellets[*]Hornady SST's shoot decent, but are a b*%^h to load[*]My gun shoots saboted 300 grn bullets much better than 250's[*]APP Shockey's gold shoots well and cleans easy[*]Shockwaves load easier than Hornadys[*]Remington Kleanbore primers did nothing to improve the crud ring when I used 777 pellets [/ul]
I found with my Omega, much the same as treetopflyer.
However I did notice that I was having a hard time aligning my eye to the scope consistently. My remedy to the situation was a cheek pad 1/2 inch. I now get much more consistent eye alignment.

Bullets....240 - 250 gr anything...didn't group well
300 sst's same as treetop's
Best most accurate was PR's 340 gr Dead Center's. Say what you like about the company, but those bullets fly like a charm. Load was 2 T7 50grpellets w/ a winchester 209's. I think Cabellas has them as well.
