Re: chambering for 300rum for long coal?
I have had extraordinary luck with the regular Sammi spec chamber. The freebore is pretty long on it as they are designed. If it's not long enough just shoot a hundred rounds and check it again. The 300 Rum is hard on throats. If you build it extra long it won't be long and you will run out of magazine. Another good thing is both the Berger and the Noslers are very forgiving for distance off the lands.
