I won't give up on Lee 200gr SWC in 1911 - but I'm sure struggling

I already ordered a replacement Tisas barrel. I’ll be more cautious if I elect to cut the replacement for 1/32” gap. I also will check the frame ramp more to ensure that was even cut or angled right.

Bummer since it feeds now but it’s important to me any gun be safe with any factory load (potentially) even though my loads are always quite light relative to premium factory.

45DUDE's pics are an excellent guide for what and how much material to remove. As long as the barrel is clear of the frame ramp you are fine. You'll notice where his barrel meets the frame has a fine edge. Not a knife edge but but no extra as far as height. It's a straight line from that edge to edge where the ramp and chamber meet. That edge where ramp meets chamber should have only the minimum material removed. NO POWER TOOLS TO ACCOMPLISH THIS! Very light passes with a piece crocus cloth so the sharp edge is gone. And then POLISH the ramp and edge with the felt tip moving constantly. Go slow and check your work often which is always the procedure for working on guns and ammo. And it all doesn't have to be done in one sitting.

[QUOTE=gidaeon;5907300]I already ordered a replacement Tisas barrel. XXXXX Measure the new barrel to fit like the original. The barrel looks properly fit to your gun. Chances are fair it may drop in with little fitting being it's a Tisas barrel. Rear of the lug looks good. Maybe put a piece of thin paper between the hood and face and drop the slide to see if it cuts the paper. Good luck. A new barrel may work with a lswc without doing anything.

I should have mentioned that the frame ramp should only be polished.

You never mentioned where the rounds were jammed (what position they were in) but a dent 1/4” from the end of the case is a hard three point jam.

Never attack the barrel ramp such that the top corner of the ramp is extended further into the chamber. You can soften a sharp edge there slightly but no more. NO DREMELS!

I will get a picture of the difference between tapered lip magazines and the typical (unreasonably) popular wadcutter magazine along shortly. The tapered lips are truer to the original design the gun was intended to use. JMB knew what magazine design was intended and specified it for a reason. Most people wouldn’t know the difference if they stared right at them.

It matters.

Guess which design feeds at a flatter angle? Hint: not the McCormick on the left. Those are my thumbs in the photo. The magazine on the right was part of a 15K group buy when we commissioned Checkmate to make a large run about 17 years ago and we paid about 8 bucks apiece at the time.

They are now a regular catalog item and the weld mark up the back is buffed out to invisibility.

Both magazines have the cartridge positioned far enough forward that release occurs just barely further along.

Much of what is promoted about 1911 magazines is snake oil. JMB’s iteration with tapered feed lips is truest to the desirable 1911 feed profile. This knowledge has largely been lost to detrimental effect.

The barrel ramp is not a feed ramp. The frame is the feed ramp. The barrel ramp is a clearance and is not something that is meant to to be hit by the nose of the bullet. This is also not well known.

Where can I buy those magazines?
