Thanks johnnyk;your info was very helpfuland thanks for the warm welcome,i've been loading for only a little while and mainly use Nosler and Hornady Bullets and just needed a little help with the sierra's again thanks for your help.Hey man, welcome to LongRangeHunting. Good choice of caliber, bullet and bullet weight. I have never used the GK but have shot a boat load of the 150gn Nosler Ballistic Tips through the two 7Mags that I owned.
My Remington Sendero liked the 150gn pushed by 67gn of RL22 and CCI's BR2 primers. My 700P liked the 150gn NBT pushed by 63.5gn of IMR4350 and Remington 9.5M primers. Both these loads gave me sub 1/2" groups and have been the demise of many a creature.
Check out reloadersnest.com, accuratepowder.com, alliantpowder.com, hodgdon.com and ramshot.com. All these are loaded under my favorites for quick ref. Good to have so you don't have to buy all the reloading manuals.
Hope this helps in your endeavors and again, welcome. JohnnyK.
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
