[QUOTE="Fitch, post: 417151, member: 19372"] Glenn's suggestion to chronograph some factory loads is excellent. Exactly what bullets are you using? What are the sources you are referencing? Looking at my "library" I see Nosler says 65g is max. Sierra says 63.2g is max. My (2006) Hodgden manual has no listing for H4831SC and 150g bullets. I pretty much shoot 160g and heavier bullets in my 7mags. Shooting the 160AB in the Ruger 77 MK-II with a 24" barrel I get my best group with 62.5g of IMR4831 @ 2990 fps with an ES of 22 fps. 63.0g gives me 3032 fps but a group twice as big so I go with 62.5. If you tell me the bullet and COL you are loading to I can model it in QuickLoad and see what I get. Fitch [/QUOTE]
