Since the reloading thread I’ve been thinking about freebore in the Dagger barrels. The pistol I bought had the threaded barrel and I wanted the non threaded barrel. That pistol just wasn’t in stock at the moment and I had already decided to pull the trigger (pun intended) on a Dagger and I wasn’t waiting! So… I also ordered a shorter barrel. It’s just a little more OT anyways.
But, now the issue of freebore came up. With the shorter barrel for some reason a 125gr lead RN bullet at a typical COL of 1.125 wouldn’t chamber properly and would get jammed in the pistol. Today I took the barrel out and looked at the freebore (sorry, no pictures). Usually there is a small distance of freebore, somewhere around .050 - .070 before there is a taper of 1° to 1.5°. I don’t know the actual dimensions but that is about it, maybe someone with more info could chime in on that. Anyway, I looked at the freebore in the original threaded barrel and that was pretty much what was there, about 1/16" of freebore and then taper. Looking at the non-threaded barrel, there was no freebore at all before the taper.
Anyone know the spec’s that PSA use to make these barrels? What are the dimensions for the freebore that they use?
so i also swapped a threaded barrel for a flush cut… and the other way around too… but I’ve had zero issues and don’t really understand anything you just said tbh sorry… but i did a mag dump with 31 rounds and zero issues if that info helps… i have not tried gen5 barrels in a dagger yet but it’s tempting because i have a few.
nope, doesn’t help. No big thing. In the reloading thread there was an issue brought up of certain bullets jamming in the freebore section of the firing chamber. I had one barrel that gave me no problem and another that would jam a 125gr LRN and cause issues. One of which was that I couldn’t clear my weapon. Not a good thing. I then checked both barrels and found that one had an average freebore section and one did not. Since it isn’t much of an issue for anyone, I decided to get another barrel at some other time if the urge comes over me. Or maybe I’ll get a chamber reamer. Dunno, making it up as I go.
Ok, this is my 1st post here and, i will admit, i didnt read the thread you are referencing. HOWEVER, i have had very similar problems with two other guns - my CZ P10c got sent back to CZ to get the throat cut a little deeper, they said it was a known issue because they’re made to some commie spec, not SAAMI. The other time this happened was with a Gen3 Glock 23 that had a Storm Lake barrel. In both instances, i was running reloads (once my own, once some factrly reloads).
My gun needed impact to open. It was slightly out of battery and STUCK. Is this the issue you are having? I had figured the nose of the larger ogive bullet was too far into the short throat. Since then i have learned about “push through sizing” and why it exists. A normal sizing die resizes the case WALL but the “floor” (for lack of a better word) can NOT be resized by a standard resizing die. I am talking about the bottom portion of the inside of the case, the part with the flash hole for your primer. In a “forgiving” chamber, the (basically) brass disc is allowed to swell. If you resize that case, using a normal deprime resize die, that protion will remain its new size. Now, put your newly loaded round into a chamber with not so forgiving tolerances and it gets stuck. The solution is a “push through” sizing die in which the entire case is ran completely through the die and out the top of it.
This might not be your issue but it might be something to consider before definitively blaming the front of the chamber.
Thanks for the reply. Yes, this is what is happening. When I did finally get the round out of the barrel I noticed on the area just in front of the ogive of the bullet, the bullet had been marked by the rifling. The bullet was getting jammed into the rifling because there was no freebore before it taperes into the rifling. I ended up setting my bullets .035 deeper in the casing and they fed fine. That’s what got me thinking about this issue. I also found that jacketed bullets seemed to feed fine but I haven’t shot too many jacket bullets through this barrel to test different loads.
I’m a little late to the game but I just purchased a dagger w/ optic combo and am very suprised at the short throat it has. I have to decrease my loads by .04~ average. Even federal HST factory loads will get stuck in it. Looks like I am off to find a new barrel.
I have 2 barrels. One has what I would think is a typical freebore and I don’t have problems with rounds sticking but the other barrel doesn’t seem to have a freebore at all and I can’t use it. Probably going to get it reamed better since this is the barrel I actually wanted. Was also thinking of just getting a Faxon barrel.
I have a Faxon barrel, and the freeborr on it is very tight also. I can only load XTPs to 1.07. OAL to keep them in solid plunk test range. Most published load data has them at 1.10. To be fair, all 3 of my Gen5 Glocks have almost the exact same throat, as does my factory Dagger barrel. So I don’t think it’s out of line, just typical of “match” grade barrels.
I was just over on a Glock forum and it looks like the lack of freebore is a problem for some there also. I don’t want any unusually long freebore, just long enough to accept a typical cartridge with RN bullets.
