A few days ago I posted a thread about a .257 Weatherby with a fouling problem. It definitely has a fouling problem, but I am not sure I got the straight skinney on the rifle when I bought it. Previous owner said it had never been shot. That was before I knew much about chambers, throats, lands etc. Now I am thinking I got reamed, but not sure. Gun looked as though it had not been fired (at least noticably). Wood was immaculate. Blueing was ummarked. Anyway, I know that I have not fired in excess of 300 rounds through it. The carbon fouling is remarkable and I am working on that currently, but what has me concerned is the throat. In all of my other rifles I can see the distinct edge of where the grooves start. Some of my rifles are more worn than others, but I can still discern them with ease. Not so with my .257. The grooves come down and it is difficult at best to see. I think that casting the chamber might give be a better idea of what I really have. Really starting to wonder if it is time to retire the barrel.

Anyway, what is the easiest way to cast a chamber that will give good results?

Thanks for your help.

I'm not answering your question...but trying to be helpful. If it's a Weatherby rifle return it to their authorized agent for repair....and specifically ask for a new barrel.

If you are looking to make a chamber casting go to www.brownells.com and do a search on CERROSAFE. It melts between 158 and 190 degrees I believe and can be used over and over again. Hope this helps.

300Winnie,

Are you aware than Weatherby cartridges have freebored throats? Thus there is no rifleing after the neck for about a half inch.
