Gunsmithing T/C Encore question

[judgedelta]

I've got an Encore with a .35 Whelen barrel and was shooting a 225 gr. Hornady ballistic tip over 54.4 grs. of RL-15. I noticed that the primers started to back out. Primers are not flat and no cratering. Anyone know anything about an Encore? Is this typical? Is this dangerous?

Thanks...

Re: T/C Encore question

Check out mike bellm (sp) TC site. It gives a wealth of information on headspace issues with the TC break open guns and some info on how to correct the problem. You can start out by checking your brass for excessive stretch due to too much headspace and go from there. I had one encore barrel that was just too far out for my frame to correct. Not necessarily unsafe, just too hard on the brass.

Not sure of your load but I have an encore 2506 imp that with light loads will back out primers. There isn't enough pressure to push the case head back to the breech. However the primers do get pushed back to the breech or back out.

Re: T/C Encore question

when you resize your brass just barely give it a shoulder bump.

the case head used the frame face as a breech face so their is a ton of pressure their and the firing pin on the Encore retracts after the hammer strike so the only thing to stop the primer from moving in the breech face so it'll often scoot back to make flush with the case head.
Ive had several factory barrels do this , returned to TC they come back saying they are fine one was a 270 and the other was a 22-250.

Is your barrel an after market barrel or somthing sombody rechambered?
the Ackly case is actualy slightly shorter measured to thge datum line than the factory 25-06 , this causes a slight crush fit on bolt gun to ensure that their isint an excessive headspace issue when fire forming loads.
I rechambered a buddys heavy 25-06 Encore to 25 Gibbs and it worked great , we used 30-06 Lapua brass and only partly neck sized the cases so that the origional neck acted like a false shoulder to hold the casetight against the breech

Re: T/C Encore question

Thanks for the info guys. I'm running a 26" T/C factory .35 Whelen barrel. This is the first load that I've noticed the primer problem with. Sierra lists 54.4 gr. of RL-15 as a max load, but they are known for light loads. The rifle is a moa shooter even with the primers backing out.

Re: T/C Encore question

Id back off to 54 even and call it good if the load shoots well , i assure you that "ol buck" isint gonna notice that your load is .4 gr shy.

The 35 Whelen is a freakin hammer with bullets that expand quick.
After deer season try some 180gr Hornady XTP's out of it , 58gr of H335 and HO-LEE-CHIT its like shooting little grenadeds

Re: T/C Encore question

As JJones says...I have found that earlier Remington brass was a bit short for the Handi Rifle and I had to do as he says...I expanded the neck up to .375 and resized it to .35 leaving a false shoulder. Once fired it was fine.

Actually my barrel is an aftermarket by what was a very reputable company that is now no longer in business. They f'd it up, then had to recut the chamber (still f'd up). This was one of the first semi-custom firearms I ever purchased. It is essentially a wildcat chamber as there is about .025" headspace on a factory case. (Some federal factory loads I had would give case head separations on the first firing). To get around this, I use 280 brass and bump the neck/shoulder junction enough to chamber, then fireform. Otherwise, I have to create a false shoulder by necking up and back down.
