Made some dummy rounds for my cz 550 416 rigby. measured col to lands and they are not touching lands. All 6 fed and ejected fine. bolt seemed a bit tight at the last part of closing but no marks on brass. Loaded up some work up loads. chamberd round and bolt close seemed a bit tighter. Ejected round, compared to dummys and all was the same. reloaded it thinking i would close it then eject it and look with magnifier to see if any marks. Now I cant open bolt, not even with rubber hammer. What to do? Its loaded with 90 gr of IMR 4350 with a 350 gr tsx bullet. Just shoot it out and see if that loosens it? Never ran into this before. In fact I've never shot a round so hot I couldn't lift the bolt. | ||

I'd loosen the action screws a bit and see if the bolt will open. If not, tighten them back down and let 'er rip. I don't know, what else can you do? Is the safety working the way it's supposed to ? | |||

OK first off you are handling a loaded rifle. Can you fire it safely where you are without transporting it to a safe area. I would fire it off pronto as you have already tried a rubber hammer and anymore mucking around trying to open the bolt is getting into dangerous territory. I assume you have checked that your cases are trimmed correctly, if so check chamber depth of the neck. Could be crimping the neck in the chamber as the bolt locks into battery and distorting the shoulder. The 416 Rigby is known for folding shoulders, due to the rather sharp shoulder and large diameter neck the case has if not chamfering the case mouth properly and seating bullets carefully, this could be happening either when seating bullets or when chambering if the case mouth is being pinched. It would only take a fraction of distortion to make hard chambering and lock the bolt. | |||

Safety works fine, good idea about action screws, will check but I doubt problem. 30 inch lbs on front 15 on rear. wondering if I leave it in front of heater over night ? also wondering if there is something in lug recess? did a quick swab of thing when i got it home but maybey not good enough. Thanks | |||

Shoot it. When cases stick, it is usually/always that the chamber is smaller OD than the die. As I say, it is a miracle that we have as good luck as we do, given the huge tolerances allowed and used by reamer, die, ammo, and rifle makers. Yikes; just read this; Do NOT put it near a heater. Bad idea. | |||

Shoot it out in a safe place like a range or soft dirt bank. Be safe. No more hammer for you.  Life itself is a gift. Live it up if you can. | |||

Yes upon closer inspection the shoulders are visibly distorted. I can only assume that due to the fact that I used the roll crimp on rcbs die I caused this ( I have never used that before ) incorrectly ? I have lee factory crimp die, but not the press to use it as it is larger diameter die. always something new Thanks ! | |||

So the Lee FCD is not the standard 7/8 14 thread ? | |||

Good at least you have found the problem, the stuck case will be fine to shoot fireforming the shoulders back to spec. I always resize new brass and give a good chamfer to the case neck with my Lyman VLD chamfer. Factory brass today is often roughly finished so I never load new brass at it comes from the manufacturer. Nothing wrong with roll crimping with an RCBS die but best to do it as a separate operation rather than at the same time as seating the bullet and of course you need a cannelured bullet to roll crimp. Due to that sharp shoulder on the 416 Rigby case you need to be cautious when roll crimping and don't over do it. | |||

On my Rigby CZ550, I use a seperate crimping die. Don't know if you do or not. When I first started reloading for the 416, I seated the bullet and crimped in same die. Even with cases trimmed the same length, I still had a few fold on me. | |||

Try doing your seating and crimping in two different steps. When I load for my 416 Rigby or 375 H&H I seat the bullets with the die set not to crimp. When the entire batch is loaded like that, I back off the seater, so it won't seat the bullet any deeper and adjust the die body to crimp the loaded round. Don't overdo it with the crimp.

Shot the stuck round, all good and ejected clean and easy. On the bright side , after 20 some years looking at the top of my rcbs press, I finely found out what the 6 sided nut on top was for crimping with my lee factory crimp now. As a side note, it looks like the cz will be fairly accurate shooting 350 gr tsx bullets at 2550 fps thanks guys ! | |||
