I recently purchased a Witness Match 10mm that has been having some loading problems. I reloaded some 10mm ball ammo(165gr. 9.6gr. Power pistol) and when it jams, the round is feeding into the top of the chamber. The OAL i set it to is 1.256". I also used some double TAP(Speer 165gr HP and 200gr ball) and their OAL is 1.25". The speer hp's are hitting the feed ramp and the ball is also hitting the top of the chamber. I went through 50 rounds of factory American Eagle first, then 75rds of reloads and 30rds of the double tap stuff(15 each) or 155 total rounds.

My question is, would shortening or lengthening the OAL help with these feed issues. I have a Sprinco recoil reducer and had an 18lb Wolff spring. Im thinking either the case length needs adjusted or the slide is moving back and into battery quicker than the next round is being fed. I have the others springs(16lb, 20lb and 22lb) but have yet to tinker with these. Any help would be appreciated.
 
I have loaded rounds as long as 1.260" and they fed just fine in my Glock 20.
I used 7.9 gr. of Power Pistol and 180 gr Rem Gold Sabers.
