I shoot two 7mm rem mags and one i shoot 59 grains of H4350 with 168 berger vlds in a sendero special 24 inch barrel and i get 1/2 moa @ 2900 fps. My other is a custom barreled 700 with 26 inch shilen and i use 69.5 grains H 1000 and I also get 2900 fps with 1/2 moa shooting 168 berger vlds. They took some time to get shooting but these are the best loads i found. these are not starting loads so may want to back off at first.I need a little help with some starting load data. I just purchased some Sierra 168gr match kings and berger 168 gr vld. I'm looking for a good load for my Remington Sendero 7mm. gun)
I shot 3 different 5 shot groups with this sendero and the best group was 1.5 moa at 100 yards. That is unacceptable. I have this gun in 22-250 and it shoots the 55gr bergers 1/2 moa all day long. What's the first thing I should check before a get rid of this rifle?
I broke in the barrel as per instructions on this website 2 months ago. I replaced the factory trigger with a Jewel and it is unbelievable. As far as bedding goes, I assumed it was already glass bedded. How would I go about trueing the action?
Before you spend tons of money you might try playing with seating depths especially with the Bergers. My factory 700 was a little fussy with the Bergers. I think I finally settled with a COL of 3.380" with 72 gr of Retumbo and Fed 215's. Good luck!
