Tuning FX Dreamline action/pellet probe issue

So I have an fx dreamline classic in .25 



Sunday I shot all day long no issues, Monday tuned the rifle no issues (only adjustment made was hammer spring, brought it up to 912 fps) 



Reassemble rifle. Go and shoot yesterday.



Nothing but issues, thought the magazines were bad but they worked fine in my buddies dream tact, and saw no damage. 



It seems once the pellet is out of the mag and first enters the breech my prob pushes it at an angle? It cut the skirts off a few pellets (that I noticed) , it is about 30 % of the way into pushing the cocking lever forward that it becomes hard and I have to force it....



Any insight?



Thanks in advance

Blew a breech oring, my God was that frustrating

You couldn’t hear or feel that it was blown? The reason I ask is because I’ve never replaced the probe oring on my DL and was just kinda curious if there were any other symptoms than difficulty seating a pellet.

Unfortunately I had my "ears" in as powder burners were going off so at the time I couldn't tell but after doing some diagnosing at home I heard a difference 100%
