I bought 1/2 a new gun for the Deer hunt this year.........

I drew a late season Muzzleloader tag this year, I have 2 gun safe's full of rifles but have never shot a Muzzleloader in my life.
I only put in for the tag for the season dates, I was talking with one of my friends that is a gunsmith and told him my dilemma.....
He said let's make you a switch barrel Muzzleloader, so I took him my Win 70 220 Swift Heavy Varmint. With this rifle he would not have to inlet the stock because of the heavy barrel.
I just got it back a couple weeks ago, a 45Cal Muzzleloader fit perfectly into my stock. Just shot it yesterday and it put 4 300gr bullets into less than an inch at 100yds..........when the hunt is over I can change it back to a 220 Swift in about 5 minutes
