I bought a Stevens 200 .223 back about a year ago and have enjoyed shooting it. However, it will not feed anything with certainty. I have tried WWB 45 gr. HPs, Dogtowns 55 gr, and VMAX 55 gr bullets. Everything seems to get caught up not hitting the feed ramp correctly and goes into the chamber too steep. Anyone else have this problem with their 200? What was the fix?
