On my annual Oct.trip to the great smoky mtns. I always run up from the in-laws to see Tip to visit and look at some rifles, I was kinda looking for a deer/hog gun but I didn't want a super long barrel, I handled some jaegers but they just didn't fit for me, so Tip shows me a lancaster style of some sort I believe with a colerain 38" OTR .62 cal. nice maple stock,brass hardware, felt good on the shoulder which sold it for me, so I had him box it up and ship it home so I wouldn't have to drag it around for a week or so in the truck, so he sends me some .600 balls and some jags and a note saying start at 80grs of 2f so I grabbed some goex today and loaded her up, first patch, too thin, I dug around and found some denim that measured about .025 really tight to start and the first few looked cut when I recovered them, I shot 25 rounds at 25 yrds used beeswax/olive oil lube that works in my other guns, but the grouping seemed large and inconsistent, I know I have more shooting and tweaking to do but please share your load combos and advice, I know these deep grooves need a thick patch but this would be tough in the field if a second shot was needed quickly, what's your experiences with a new barrel of this type?
