Excellent choice Jorge!
I looked at my loading data and I use two primers in my .240 Wby. The first is a Federal 210 Match with RL-22 (the bullet is a Remington Accutip 95 grain) and the second is a CCI 250 Mag (the bullet is a 100 grain Nosler Partition) with IMR 7828.
This is my .240 Wby,it is a Ruger M 77 (tang safety) and a almost 27" barrel. The scope is a Leupold 4-12x.
Maybe a better picture of the rifle.
