I shot the 300g XTP Mag as a practice bullet in my origonal Knight Disc, which I believe is 2" shorter barrel than your elite using 100g of 777 loose and a Federal or Winchester primer.I was getting about 2.5 to 3" groups with it at 100 yards. My son has the Knight Disc Elite (maybe it is a Master hunter--I forget) in stainless, he shots the XTP Mags 300g last year with 2 777 pellets and had excellent performance with them. They have a large following in the Savage world, since that is the bullet the Savage 10ML2 was designed around. I like them because of price, $14 for 50 bullets at MidSouth Shooter's supply. I agree with Sabotloader on close shots they end to loose their jacket, reducing weight and penetration, however the weight of the lead is more than enough to kill a deer. The lead seems to stay together and not fragment, which again would hinder penetration into the vitals.Ian McMurchy who wrote "Modern Muzzleloading for Today's Whitetails":

is a huge fan of the XTP, both in 260g and 300g.

Randy Wakeman, who loves Barnes bullets, but considers the XTP an underrated bullet:

and givea lot of ballistics and design characteristics of various bullets andhe says

"For the dollar, it offers the most performance that can be had in a muzzleloading projectile."

I would agree with that statement. So >>if<< they are accurate in your gun, they are very difficult to beat, unless price doesn't matter to you thenobviouslythe Nosler, A-Frame, Barnes or Bonded SW, or "designer bullet class" will be your projectile of choice.

Anyway greetings, welcome to our campfire and we look forward to your wisdom, 44 years is a lot of ML years. I only started MLing 8 years ago, but really love it, and love learning more aboutthis art,sort like bow hunting when I was younger.Chap Gleason
