Sir
   I'm having problems loading the Swift Sirrcco 90gr bullet in my 240-Mark V, I have went threw IMR-4350, Win-760 and Reload-19, I have two loads that seem to come close and keep the bullet on the target, The target is 3" and the bullets are about 1" apart, The load is 48.5 and 52.5 in Reloader-19, I'm trying to find Tec help also to try and get the groups a little closer. I have been using the Nosler book-6 for a guide, The other loads that i try was real simply 2 bullets on target the third was 3 to 4" to the right of target
                                            I can use any help

This might not be what you want to hear, try a different bullet.  Whenever I have any accuracy problems I find that it is the bullet that the gun doesnt like.
  I had a 7-08 that I wanted to shoot the swift A-frames. In my mind it was perfect for antelope and even Zebra. It never shot below a 3 inch group with them.  I tried Sierras and the group shrunk below an inch.  Some guns are just a little picky on what they like.

Hornady's 85 grain interbond should deliver simialar results downrange.
