Hi,
I'm new to the forum here but wanted to see if anyone out there has any experience in building an inline for deer hunting up to 250 yard shots. I do my own barrel work, and have an old Ruger 77/50 that has a rusted and pitted barrel that I'd like to replace. Any suggestions on barrels, twist, bullets, powder choice, ect would be appreciated. The Ruger 77/50 action is the one they use for the 22 LR, so they do not recommend upgrading to a 209 primer system; it uses the #11 percussion caps. Thanks
 
I’d install a quality stainless .50 inline barrel with a faster twist to stabilize heavy conical saboted bullet, you can also use modern black powder substitute or FFG loads. You should est accuracy at range and stick with reliable #11 percussion caps

I'm no long-range expert but I once went out with a friend whose new rifle looked great. When he shot, there was so much smoke we couldn't even see what he hit :), I will always advice you keep things simple

If you're shooting that far with that bullet weight, a 1:24 or 1:28 twist barrel with a 300-grain conical bullet should do the trick.
 
I would refer you to Modern Muzzleloading forums. There is more info there than you will ever be able to absorb. Some there shoot and compete to ranges I would use an odometer to measure. I visit there daily but I have very little to contribute. Couple on there compete and shoot to 1200yds. Now of course for the really long range stuff there are some top shelf custom guns involved. Most there are hunters like me where I’m happy to 100-150 yards. What I have learned is that a muzzleloader is a lot more technical than most of us realize. Something as simple as switching to a different primer can(will) change your point of impact. Every little thing is important!!
