GG, The BOTW ammo is good stuff from my limited experiences, and extensive experience from some of my customers feedback.
That was a test group from a brux barreled sendero for a customer in Florida. I shot 3 sighter then that group with BOTW 168 berger load. It was 13 degrees out and I shot it off a 6x6 wood block with one of my gloves laying on top of it, and my fist for a rear bag. The man that recieved that gun does not handload and shoots 3 different cartriges with BOTW ammo and reports excellent results at long range. He said that 7mm mag has produced 1/4" 100 yard groups for him on numerous occasions. I do not doubt him in the least.
I have a Huskemaw
on a 7rum shooting 180 bergers at 3160fps. When I called Arron to set up the turret he told me to shoot data for 200,600,800 and if I could 1200 yards. He would then calculate the TRUE bc of that rifle bullet combination under my alt. and conditions, and then build me a turret for the alt and "standard" conditions I would be in out west. I had him make my turret for 9000 ft.
On my trip to CO this year I put my first bullets on a Mule deers shoulder at 826 yards. After zeroing the rifle at 400 the day before at camp.
Did I dial to 826?, no I compensated for a 12 degree angle by coming off one click. That is a necesary adjustment of LRH with any scope system. I shot rocks on that trip out to 950 yards, and was never off my verticle point of aim more than 2-3" basically with-in the rifles ability to group at those distances.
I was in Montana a few days in Nov. and used the same set-up at 8000 feet. A bit colder as well. I added a click for the longer shots and had no problem with hits on shots I took at rocks out to my furthest on that trip as well. Sure I could have had another turret made, but I did not see the need for ME.
I personally liked the system and the fact that wind data is on the turret with the yardage marks. Ask my CO hunting partner, He forgot his moa drop chart for his NF/300 rum set-up. Made him the designated spoter for the day.
