Good to hear. That "click" followed by opening the bolt with bullet still in lands and ensuing powder issues is a show stopper.

It sure is...how do your “Jammers” manage this in a tournament?

you shoot right when you here seize fire!,,,
No, , I know you shouldn't do that but if your jamming a round that hard for a fire formed competition load I've seen guys stand rifle muzzle straight up snap the bolt open then drop one of those brass rod things down the bore to knock bullet out.

Usually match loads are not jammed in hard enough to stick in the land's and it will un-chamber ok.

but it does suck when powder dumps in the action, I did it twice one on a Panda, and one on a Savage.

Lucky for me it happens fireforming. In a match I think it qualifies as a "train wreck." Either situation it's a pita.

Fireforming saga continues. Have come to the frustrating but enlightened conclusion that hydroforming leaves me with .010 shoulder movement to fit my Brdx Borden chamber and no matter how tight a neck bushing I use on the case in the .270 neck chamber, the firing pin still dislodges the case enough that there isn't ignition. This with seating .012 to .015 into the lands. Have followed gunsmith Vantassel's suggestion of false shoulder, and voila, no issues at all. Federal primers help, hopefully I have turned the corner. Fireforming at 300 yards, 3 inch groups. Life will get better, they tell me.

Try seating more like .100" in for full jam. I've fire formed about 500 BRX brass this way and never had a failure to fire. Take your ejector out if you have one.

Thank you for info. Right now false shoulder is working 100 percent, relief after previous experience with 2 or 3 out of 5 not firing. No ejector.

JMO, but the false shoulder method is the way to go!! I use a good solid crush fit and I ALSO jam the bullet fairly hard with tight neck tension....a threefer!!!

I ran the 105 Berger BT with 31 Varget with exceptional results. The reason I never used this load in comp was that fact that the "crush fit" makes the bolt close hard and thus upsets the gun in the bags when I chambered a round. Also...that 1 in a 100 where the brass splits on the shoulder and the shots drop way low at 600/1000 would WRECK a target!! This is purely a bad brass thing, and you could actually see a defect on the brass BEFORE you fired it.

LOVE THE DASHER!!!
