First, I am not a gunsmith and I am only sharing my personal experience in the hope it may help you.
1) I have not had good results with the Wilson mags feeding 200gr SWC. Metalform mags seem to work much better. The feed lips on the Wilson mag release the base of the bullet latter then the Metalform. This seems to tip the front of the bullet higher and makes it more likely to snag the top of the chamber.
2) On some match barrels the "bevel" on the entrance to the chamber does not completely blend into the hood of the barrel and the mouth of the case catches when using 200gr SWC bullets. On my guns which had feeding problems with 200gr SWC: a 1911, a Glock 21 and a Sig 220, I was able to fix the problem by blending in this area of the chamber entrance so there was a smooth transition into the barrel hood.
Good luck. Hope this helps you.
