My 1911 has always had an issue with causing bullet setback.
Its a Taurus PT1911 which i hate mentioning as i hope to not get remarks about who made the gun.
But the gun always feeds reliably both FMJ and HP's and it will cause setback on both types of ammo.
Im always rechambering HP's after cleanings after a day at the range and also if i take the gun down to work on it as its been going threw a rebuild.
But i always keep it loaded and chambered as its my main ccw weapon.

I had forgot until just now but before i solved it by loading my first round and id use a FMJ and the rest HP's in the mag.

Im not so sure i could fix this myself even by following guides unless you folks think its rather easy too moderately challenging.

NO work has ever been performed on the ramp or throat of the barrel. But the ramp is polished and doesn't look chewed up or anything.

Is it best left alone and just keep chambering a FMJ as my first round, Or should i go in and try and fix the issue using true advice and help?

As an example a round will normally have too much setback after 3 chamberings.
I bought a 50 round box of Ranger T-Series 230gr +P and have 6 rounds i cant use now due to setback. Nor any way to fix those rounds.

Once the setback gets bad it also will cause the round to not chamber at all.
The case will catch and deform and jamb the gun if im not on top of this issue and watching the rounds. So i watch this issue closely and replace the round immediately.

I cant hand feed the chamber as my extractor just wont allow it as its the Wilson HD one and it wont play that game.

So anyone have advice or a guide i can use or should i keep my first round a FMJ and just keep replacing those? Wasting the Rangers is making me mad.

How safe would it be to partially disassemble the top end and chamber the round and then reassemble the gun? Its a series 80 gun so i think it would be pretty safe but just a pain. But id rather do that than keep wasting great ammo or using FMJ first round which i dont like the idea of either.
 
Or stop letting the slide slam shut to load the same first round over & over.

Ease it down by hand and make sure it is locked in battery each time.

Set-back is a common problem if you let the same round get slammed against the feed ramp over & over again.

Id rather rechamber the same round than the whole mag worth rotating them as then ill have a mag full of ammo i don't trust.
Also the extractor doesn't like to let the round slide under it when done slowly.
It seems to have more to do with the shape of the bottom of the extractor more than tension does.
But i can retry doing that once i get the gun back from the refinishers.

Anyhow you guys may have a point its just better to deal with it than to chance messing up the ramp.
 
Consider retiring the first round to range practice use after you notice set-back has started.

It's good to shoot up your carry ammo occasionally for practice anyway.

I have about 6 or 7 rounds already put away that i marked due to setback. Im not even gonna guess at how much deeper they are set as i always guess wrong at that type of stuff. But its very noticeable when next to a new round.
Id say i could still shoot them tho since the .45acp has such a low pressure anyhow.
 
If you are very OCD, you can mark each new round in the box around the bullet/case joint with a black Sharpie pen.

When the black mark goes inside the case neck, set-back has occurred.

When I get set back on my ammo (.45ACP) I put it in my inertia puller to pull it back out and then seat it to spec and crimp. Works every time. I carry ball ammo for SD in my 1911A1........
 
I really should start marking my rounds prior to chambering them, Its actually for a reason as if i miss one and it gets put in the mag and the setback is far enough the round will catch on the rim and jamb the gun.
Thats why im kinda anal about it.

I did carry the first round with a FMJ chambered and the rest all HP's, I may go back to that even tho i have much more trust in HP's.
But if i need the gun in a situation im sure ill be shooting alot more than just 1 round so the single FMJ will be no issue.

Ive seen the pullers but ive not been willing yet to invest in one.

Anyhow i think you all make a good point that its best to just deal with setback than to mess with the guns ramp and chamber lip.
 
There are two effective ways to deal with setback - 1) don't ever buy that brand of ammo again because it's junk. 2) learn how to reload.
 
Setback is caused my improper loading techniques...and I mean loading the ammo, not the gun.

I fought with setback for years...up until about 6 months ago when I finally figured it out.

DO NOT CRIMP the rounds...leave the diameter at the mouth at .471" - .472", and let the case tension do its job...which is hold the bullet FIRM.

I have a round, loaded with a 230 grain XTP bullet, that I have rechambered "at least" 50 times now (purposely)...and the round still measures 1.23", just as it did when it was first loaded.

If you don't have enough case tension...switch brass brands (I use Remington...mostly), if that don't work check the inside diameter of a resized case...your dies may not be made right.

All this is with my 1911 (a Baer) that was notorious for setting bullets back....same bullets, same load...same everything, except now I don't get bullet setback.

EDIT: Thats what I get for not reading far enough...if its factory ammo...switch mag brands (feed angles), check the feedramp, check the barrel throat...or switch guns (not an anti-Taurus remark, just a sad fact no matter the brand...fix it or deal with it)

Good luck

And I'm not picking a debate with rcmodel...not at all.

But if I ease the slide forward on my pistol it won't feed the next round...I have yet to figure out why, but it nosedives the next round EVERY time if the slide don't "go home" with authority.

And it does this no matter which mags I'm using (I have Tripps, Wilsons, and Baers...I carry the Tripps)

Tuner..if you happen to read this and can solve that mystery for me...I'd very much appreciate it.
 
Well, that is a problem with the feed ramp angle or the magazine or possibly the ammo. The gun should feed properly whether the slide is eased down or released to drop hard. If it doesn't, that is the basic problem, not concerns about bullet setback, which is happening because the slide goes forward and the round doesn't feed smoothly.

I only use factory ammo, Both in FMJ and HP and it happens to both.
Its done it to every ammo ive ever ran threw it no matter who made it.
The mag is a Wilson 47D, As is the extractor a Wilson HD part.

I have the extractor tension set to guides ive read online and it has had no issues for 1k rounds so im not about to go loosen the tension just because it wont allow me to slowly lower the slide as im pretty sure its the cause of not allowing me to slowly drop the slide.

But the setback is from the feedramp imo. I honestly dont want to go cutting on my feedramp, I think if i did anything id leave it to a real smith as the gun is 100% reliable and i dont want to mess with that.

I think ill just live with it causing setback and possibly switching back to using FMJ as my first round so i dont cry over smooshed Talons.
