1:28 Twist

[rrush]

My wife bought me the 209x50 ML barrel for my Encore for Christmas.  It has the 1:28 twist.  Will it shoot heavy conical bullets ok at this twist rate?  My son inherited my TC Greyhawk in 54 cal with a 1:48.  That shot my hand cast 430-grain TC Maxiballs great out to 100 yards.  Sabots are not allowed in Colorado for hunting so I’m leaning toward the Hornady Great Plains and the Powerbelts.  From what I have read on these forums Powerbelts are not that great at higher velocities.  TC literature states the 1:28 is for sabots and conicals.  It seems the 1:28 would be to fast for a 400-500 grain conical.  Any comments would be appreciated.

Powerbelts are very soft and deform quite a bit, so penetration on elk would not be "all that great." If you must use them I would get the 400g+ ones. Actually 400-500g conicals should shoot great, with proper powder and loads, with the nod going to the 450g KN from pr bullet.
www.prbullet has a great selection as well as excellent tech support if you need it.
