Thqanks guys for the replies. Firstly, that .416 rigby load is not showing any signs that I have gone too far. My cases extract easy, bolt lift is easy, primers are OK so I think its a pretty safe load. It does get my attentin when fired but its not bad, I get more bruised from my .270 Rem 700 mountain rifle, and .340 wby mag when shooting off a bench.

So I guess the only issue with this rifle is that the ruger number 1's are just too light for serious big bore cartridges? Does anybody know if they can be made heavier? Lead in the stock, to ballance out a long heavy barrel maybe?

Would be a nice little project for me, but it has to be shootable, dont want to have it sitting around doing nothing.

thanks again
Steve
