I've tried 3 kinds. the first was ...winchester(? cant say for sure) 7 1/2 Heavy Target. this stuff ran fine on gas setting 2.What type of ammo are you running through it?
then I bought some winchester white box Super Target. thumbs down on that. FTE on every round. I only have less than 100 rds thru, so I may yet get that stuff to work.
now I have some winchester black box Super Handicap 7 1/2. this is some pretty potent stuff and cycles the action no problem.
00-Buck on gas setting 1 runs just fine as well.
I also have an 870, but like the saiga alot more. reloads way faster , recoil is less, followup shots are quicker.
at the IDPA I attend, after the match is done, they let you run one of the stages a second time with shotgun (replacing targets with steel). I ran this with my 870, and am slow as molasses reloading. I havent yet had the chance to try the Saiga at a match, but will likely do it next Sunday.
you gonna spring for the 20-rd drum?
