If you are on a budget...
I bought an alphaarms 15SA shotgun.
for $500 its amazing.
I ran over 200 shells through it yesterday (breakin) the only shells that caused issue were winchester handicap #7.5 shot... which is pretty light loadings. even then it only stove piped maybe 4 out of 75 shells as the "problem ammo"
It ran slugs brilliantly, buckshot without issue, and of 100 super cheap challenger HV 7.5 target load only 1 stove piped, cocked back the action, quick tilt of the gun to drop it out and i was off shooting again.
nothing rattled loose, the sights stayed zeroed (tested with slugs at 50m start and finish), it didn't bog up
I would highly recommend one of these if you want a Semi without breaking the bank. I'm not sure of the over all longevity of the shotgun, but i would be surprised if it didn't make at least a couple 3 gun seasons.
