How do 9mm truncated cone bullets feed compared to round nose?

[ysrracer]

Anybody shoot 9mm truncated cone bullets? How do they feed compared to round nose?

 

Specifically 124gr bullets.

[Sarge]

I have shot a case of BBI 125’s which are TC. They ran just fine in XDM, 2011, Glocks and PCC

[mveto]

I run the 135 tc in all my CZ’s and PCC’s and the feed and run great, no issues at all.

Just like RN—find the COL they like and they work just as well. Never had any problem with getting any bullet to feed and chamber (JHP, FN, SWC, whatever) in any gun I have, provided I took the time to find the COL that worked. Heck, I had SWCs flying through my 1911s long with milsurp magazines.

Obviously, you can't load them to the same COL as RN, as they have had part of the RN truncated.

Shooting a case of Black 125 TC now and they all work great.  Waiting for 125 RN Blues to come in.  As said above, shouldn't matter if setup correctly.

The only problem you may run into is shooting wide meplat TCs in certain PCCs.  For instance, the Federal Syntech bullets will not feed in the Wiland barrel on my PCC, but will feed in the Leadstar barrel.  TC bullets feed perfectly in all my 9mm pistols.

I've shot thousands of this particular 125 gr conical nose bullet seated to 1.10" through a CZ P-10F, P-10C, P-09, P-07, and 75BD all without issues.

all i shoot are TC through my open gun

even when i lead cast my mold is a tc mold

[RangerTrace]

I had a CKARMS commander that had issues feeding 147 grain TC until Matt Cheely worked on the ramp.

[Jim Watson]

My 1991A1 9mm Colt with 1930 ramps is reluctant with truncated cones and I have a SA magazine marked "No TC."  

 

I expect my more "modern" guns like STI and S&W with integral ramp barrels would handle them ok, but why bother?  I just load roundnose.  

[Joe4d]

I agree with Jim,,  Had an old style non ramped 1911  9mm, refused to feed hollow points. So used ball, dont recall trying the TC's

Also the older Browing Hipowers sometimes didnt get along with hollowpoints. 
I am guessing anything with a modern style barrel ramp would feed just fine.

[HesedTech]

I have to assume the only reason TC don’t feed as well in old style 1911 feed ramps is the same reason why newer 1911 and 2011s have the feed ramp better integrated into the barrel rather than a combo of barrel and lower. 
 

To answer the OP they feed fine in all my guns, but I prefer other profiles, RNFP for one. Which BTW, don’t feed well in some PCC feed ramp designs. The FP occasionally hangs up on the upper edge of the barrel.

Because in this day and age sometimes you need to run what you can find and not what you would like to find.

 

It helps to have modern pistols and to know that they'll handle something other than RN.  My CZs also eat Everglades 147 RNFP like candy so long as they're seated to where they'll feed (1.05" in my case).

The main reason 2011s have ramped barrels is to get better chamber support, but easier feeding comes along for the ride.

I prefer RN,  found the profile worked a little better in my CZs due to shorter chamber. 

[2tuf4u]

My Sig all steel x5 has a difficult time feeding Winchester 146 TC ammo in the aftermarket Barsto match 9mm barrel--never tried the 124gn TC loads.

[Bowman]

I've been shooting a lot of 147 grain TC Blazer in my Glock 34 Gen 4 with zero problems.  However, 147 TC  bullets don't feed in my Colt PCC.

[echotango]

In my Legions, black TC 125's can be loaded to 1.125 max. Blue RN 125's can be loaded to 1.155 max. 

Both feed well with no issues. Might take oal into consideration. 

 

[Bakerjd]

My tanfo prefers them. I actually had to do a little massaging on the chamber to get 135rn bullets to feed well. The BBI 125gn tc bullets are very nice and consistent weight wise.

[9x45]

I've run over 150,000 of the Bayou's in the truncated cone shape, both round tip and flat tip. Like them better than RN. Bayous left, Gallant and DG right.

 

 

[Tunachaser]

They work fine in my 9 MM CZ's (135 and 147) but my Springfield 1911 in 9 MM will SOMETIMES not want to strip the first round.  I probably could have loaded longer but I didn't want to have some bullets just for the Springfield.

 

Bullets used: Precision, SNS, J-ames, Bear Creek and others.
