TS 40s&w. Feeding issue

[Czgunsalot]

Hey everyone. So I?ve been told the TS eats up pretty much everything you feed it.  Not sure if that is true because I?m my case I?m getting a failure to feee malfunction.
Next round having issue going into the chamber like a noise up jam.
This is with PMC bronze 180gr

Rams Winchester white box with no issues

Wondering if anyone has some thoughts.  I just got a few gram followers with Springs

Stop using the PMC.  Problem solved.

Are the Winchester and PMC similar bullet weights?

Similar bullet profiles?

I've only shot two bullets types in mine.  135 grain hollow points and 140 grain lead.  Never had an issue with those.  I have some lead 180 grain bullets I intend to try, just haven't gotten around to it.  Never shot a single factory round through it.

Sometimes you run into a bullet type/velocity that just doesn't work in a gun.  I used to load 140 grain lead bullet for my 9MM pistols.  XDM, M&P and CZ guns fed/chambered it fine.  My Browning would give me 2 to 3 failures to feed out of every 14 round magazine.  I just stopped trying to shoot those reloads in my BDM.

In my observations, because the CZ barrels don?t tilt as much as many other designs, the bullet profile has a big impact on how smooth the round chambers, as it doesn?t get any help from an upward tilt. I would suggest trying a different profile or weight round if possible.

I've moved to using round nose 180 or 200g bullets with a OAL of 1.123 with great success.  I had similar issues with feeding till the change.

It is possible to have bullet profiles that won't feed well at a particular OAL.  One particular bullet I've dealt with wouldn't feed reliably inside a range of .010 -- as in, it would feed 100% at 1.110 and 1.090, but not at 1.100.  It happens.   It doesn't happen a lot, but it happens.  And shooters are typically too quick to think it means their pistol has a problem.

Also, there is no OAL at which a gun feeds well.  The OAL ranges where the pistol feeds well are dependent on the bullet profile and will change from bullet to bullet. 

It is ALSO possible with a new gun that it simply needs to be broken in.  I have seen a pistol choke on a particular load 3 or 4 out of 10, then function 100% with the same cartridges after it's had several hundred rounds through it.  It is possible that this could be fixed by hand cycling it a few hundred times.

Also, make sure you've cleaned the pistol thoroughly and re-lubed it.

And finally, it could just be that pistol doesn't like that commercially produced ammo.  It happens.

Can only go by pics off the net, but comparing the two......






.....it looks like the PMC has slightly wider/rounder 'shoulders' and thus a larger flat 'circle' up top, compared to the straighter truncated cone of the WWB.  So that may be what's adding more friction or an edge/profile that having a bit more difficulty climbing that ramp....combined with less barrel tilt as mentioned.

[IDescribe]

Barrel tilt in and of itself is meaningless.  The angle of the ramp at full tilt is what would matter in that situation, so unless you want to take that measurement and compare that to most other drop barrel pistols, which you can't, it's useless to say the barrel tilts less than other pistols.  Barrel tilt by itself doesn't mean anything.

This is a pretty simple matter.  You have one brand of ammo that doesn't work well in a new pistol.  It may never work well in this pistol, in which case don't buy it, or it may start working fine after several hundred rounds.  Either way, just don't buy that ammo.

[MoRivera]

I thought it was pretty obvious that the ramp tilt was the whole point of mentioning barrel tilt, since they're one piece.  At least they are on my Tac Sport Blue and virtually all other pistols I own except maybe a 1911.

[IDescribe]

Right. 

Which means that the angle of the ramp relative to the angle of the barrel plays a role.  Which means that unless someone wants to compare the angle of the ramp relative to the angle of the barrel along with the angle of the barrel, how much the barrel tilts alone is meaningless. 

The only way saying one barrel tilts more or less than another is meaningful would be if all ramps across all pistol makes and models had the same angle relative to their barrel, and that is certainly not the case.

My bet is that it is just the shape and OAL of the PMC cartridge.  Run a couple of hundred rounds of the Winchester White Box through it and then try the PMC again.  If it jams again, it is the PMC cartridge.  If it doesn't, the gun was just a little too tight when new or the recoil spring too light to force the PMC cartridge in to the chamber while overcoming the new gun friction loads.   

I have a Kahr PM-40 that won't chamber the PMC but cycles the WWB OK.  In my case, the physical limitations of the short barrel compact are even more challenging than the TS, so I expected problems from the start.  I shoot JHP in that pistol exclusively now, which is fine, since it is a carry gun anyway.

That would essentially make the ramp angle meaningless as well, no?

I didn't see it so much as angle, as the actual ramp not being 'lowered' as much with less barrel tilt.  So the top round coming out of a mag, depending on its profile or if it's nose-diving, may not be contacting the 'channel' of the ramp as smoothly.  But yes, it'd be hard to get a pair of calipers in there.

But again, I would guess that bullet profile has more to do with it, as looking at the pics the PMC seems to have a fuller shoulder and larger flat circle than other rounds which are more like truncated cones in comparison.

Try the PMC 165g.  I found my TSO was finicky with profile and OAL.  Check your mag springs/clean the mags too.

[dbracin]

The PMC sure has a more pronounced flat face. Try other brands and forget the PMC.

Sorry for the late reply
Update
I ordered some taylor freelance base pads with grams follower and springs.  Went out last weekend and 700 rds later with the pic no malfunctions at all.

Which is crazy cause the original mags were brand new
