    New guy, 1st post, I have been researching long range muzzleloader shooting, and stumbled upon this site. After reading many threads, I decided to join up and get some education. I was inspired by some postings of a user which got me thinking.

    My gun is a knight t-bolt .50 1/28 22" barrel (my first inline). I resisted for 11 years. The max charge for this gun is 150/pellets or 120/loose.

    So I was thinking what are the velocity of the load in my gun vs a 45/70 centerfire, using the same bullet. That is a .458 sabot and a 300- 325grain 45/70 bullet.

    According to some mathmatical forumla (I read on the internet) 150 *.5 *.5 / rate of twist is the longest bullet your gun will stabilize. I calculate I can stabilize a bullet 1.33 inches long by this formula. I know this is all theory (at this point for me).

    According to this chart:
    http://www.hornady.com/assets/files/ballistics/english-ballistics-chart-2010.pdf

    The hornady 325 grain FTX (45/70) has a muzzle velocity of 2000fps. So I am wondering what the mv will be out of the knight with max load. I would hope to improve performace, both accuracy and range over the pistol bullets.

    I have been shooting traditional for 11 years, but have no experience with inline. I hope to pick a bullet/sabot combo that will be a lot less expensive than the prepackaged stuff, and perform better. Not against casting conicals if that is the magic formula. Not ruling anything out just yet.

    I must have missed the secret handshake.

    Haha..you didn't miss the secret handshake. I don't shoot muzzleloaders so I wouldn't have a clue. You are asking a very specific question with two guns that many people probably havn't had experience comparing. Hope someone replies though.

    Welcome Paleface! :D

    Don't remember if it was on here but some dude is making his own sabot and shooting normal center fire bullets and using smokeless powder. Do a search on here and some other forums, it was COOL and very very accurate in his smokepole. Good Luck. Keep us posted.

    I have chronographed similar loads at close to 2100fps in my inline with three pellets. I usually shoot around 100g of triple 7 loose for 1900+fps in my sidelock.

    The ftx is nice but there are bullets out there that are supposed to be much flatter shooting in a muzzleloader.

    Look around in this site...they have some pretty high bc muzzloader bullets.
