You're welcome here, for anything I've been able to offer.
IF you end up with this rifle in your personal keep --
Consider that this or pretty much ANY double rifle is going to be a completely new and different experience for you - and it's likely to be a handload-only proposition.
Those handloads will take a bit of load and shooter process development to get to where it's shooting right.
Once you work your way up to the right loads and the right handling skills, you'll be a permanently changed man.
You will want other double rifles.
Your 'no sell the guns' ethic will become fluid - you'll look at the rest of them as distracting clutter, at the very best you'll see them as trade bait or potential revenue stream for your next double rifle purchase.
Tread carefully.
You're at a gateway and the light from the other side of the threshold is bright and beautiful.
It's ok to take that next step, just keep this in mind...
It's very very hard to look back!
Cheers
Tinker
