Load data (ballistic info)

I'm looking for information on trajectory and average downrange energy/velocity for triple 7 powder for my Tradiions Pursuit M/L. The owners manual and video for the rifle says see powder manufacturer...but Hodgons doesn't have that on their site.

Thanx

Well, the answers depend on the muzzle velocity you're getting and the ballistic coefficient of the projectile you're using. The muzzle velocity, of course, depends on a variety of factors and the only way to be sure about it is to measure it. Do you know anyone who has a chronograph?

No...the reason I'm trying to find out is this:

They (manufacturer video) say rifle is rated for 150gr Pyrodex or 3 pellets. However in the video and manual that came with it in the loading portion, they say use 2 Pyrodex pellets or 100gr. I'm trying to find out what is the effective range for deer using 2 triple 7 pellets, is there a valid reason for not using 3.

150 grains would put it in the Magnum class.
Is it rated as a Magnum? If not I wouldn't use 150 grains.....well mabe pellets I might, but not free flowing powder. I have heard that pellets dont burn quite as fast and as completely as powder.
100 grains is a good load for most ML's, as going higher gives erratic shot groups.
