    Alf, Thanks for the reloading data using Varget. I compared various Varget loads from my old favorite 37.4 gr to 37.8, 38.2, 38.6, 39.0, & 39.1 Varget, bare 130 gr VLD Hunting 0.015" Jam and CCI 450. Never tried loads that hot before. Showed no visible signs of overpressure and didn't chronograph. Definitely showed preference for 39.0 & 39.1 gr. My rifle is a 8.5" twist Krieger and my 37.4 gr at 1000 yards appeared to fall off at 2850 fps. Hoping and thinking the 3000 fps node will hold up better. I have a Mcrees G7 stock with a bipod and Leupold 8.5-25x scope and I just can't seem to get rock steady and I'm getting 1.9"-2.1" groups at 535 yards so I know it will do better than I can hold it.

    I generally balk at giving my loads, as I always shoot moly plated bullets. Your results mirror mine and most others for the most part. Seems custom actions tend to let a person run the upper nodes as well.

    Bushing the boldface to .062" on a R700 will also allow one to run the upper nodes.

    My 700's are all bushed, however, it didn't/doesn't stop tattoos and hard bolt lifts on mine w/upper nodes. They need to run in the 37.5-38 grain nodes.

    I've got a Bighorn, and 39 grains is waaaaay too hot. Funny how some rifles can be so different.

    Again, I shoot moly.......

    Also, a 5R/C barrel can make a difference over a standard land/groove configuration.

    I run a Broughton 5C on a bushed R700...no obvious signs of pressure at 39.1gr

    I'm sorry guys, I made a mistake...my top end load with Varget is 38.1gr, NOT 39.1...I just checked that in my data book. MV with 38.1 is 2932 through a 28" 1-8" twist Broughton 5C
