I recently won a Winchester X-150 muzzleloader rifle at a raffle- It has a 45 cal barrel and a 50 cal barrel- It's brand new and has never been fired- I did some searching on the internet for info- It"s supposedly made by CVA or by a Spanish Company BPI- It appears to be an older model rifle, maybe 2005 vintage- it came with no instructions or info- Any idea where I might get some paperwork for this rifle? The person who donated the prize no longer has the papers
