Afternoon all.
I would pose a question to our more experienced members.
I've a bubba'd MKII Ross with a big 'E' hogged out chamber. It's pretty cavernous to say the least.
Does this sound like a candidate for an Epps reamer?
 
Won't really help if the hogging out is near the base of the cartridge. The Epps chamber doesn't increase the diameter near the bottom, just up near the shoulder. I think you need to do some careful measuring of your chamber to see what you actually have, then you can figure out how to modify it to your liking. - dan
 
My Mk II **** Ross has a hogged out chamber. Rather crude, the case almost has no shoulders - just a rough taper to the neck midpoint. Epping it would still leave part of this taper.
 
It actually worse past the shoulders, the mouth of the cartridge has an ID of .325 after firing. Shame too; shiny, uncut bbl.
Maybe it's just non-reloadable.
 
Chamber insert is much more expensive than the rifle warrants. It was proportedly a sporting rifle when the cash was sent...upon arrival, it morphed into a bubba'd special. So I'm a solid 350 into it already, I can't justify another 300 - 400 to get an insert built and pressed into place.
And sending it away for 6 months to a year to get it done? No thanks.
I'll likely shelve it for a while then.
 
I actually did buy a collet die set for that. But being that the open mouth of the case comes out with an ID of .325, the collet neck sizer is past what it can handle. I end up full length resizing anyhow.
I've not really taken it out for an accuracy session, but with the hogged out neck...can't be that good.
 
tokguy, can you post a couple of pictures of fired cases, beside a factory round? I'm trying to figure out what a fired case looks like.

There is an answer to this situation. Just need a little better understanding.

You can reload these cases, it just takes some care and maybe more than one neck sizing die. I've had a Ross that blew the neck out to .325 before too. I would anneal the case, then use a neck sizer for .311 (collet type) then finally move down to my 308 win neck sizing die. This was on an early MkII* with a tight .308 groove barrel (check that, early Rosses had .300 lands, .308 grooves). It was the same deal, very nicely done sporter, bright shiny bore, God awful chamber. Stupid thing would touch holes at 100m with 220gr RNs over 33gr of 4895.
