Any preliminary stats you can share yet?
What velocities are you getting with the 225 gr AB/250 gr Sinclare bullets?
What kind of accuracy are you getting?
What ranges have you shot?
What kind of brake are you using and how is the recoil?
Sorry for asking so many questions, just excited and drooling. [img]/ubbthreads/images/graemlins/tongue.gif[/img]
I weighed the gun when it had a Leupold 6.5-20x50 LRT on it and bipod and it came in at 12 pounds. I have since put a 6.5-20x40 LR Leupy on it and changed rings but I haven't weighed it again. I would guess it is right at 10 pounds without the bi-pod.
The 338 Kahn would be a sledge hammer for sure!
The only stats I can give you so far are from fireforming.
I used 82 grains of H4350 behind a 200 nosler bt before it ran out. Then I used 82 grains of Imr 4350 until it ran out. Then I used 82 grains of 1946 mil-surplus H4831.
I chronoed the break in bullets and the fireformers at 3050 fps with all three powders.
I never shot paper at 100 yards during breakin, but I did set up my gong at 535 yards to just have fun while doing the fireforming. It was fairly calm this weekend where I shoot and the mil-surp and Imr 4350 stacked a 10 shot group into about 3"!! H4350 opened the group to about 5-6".
NOt bad for fireforming with a load I had never used before!
Breakin took 4 patches of coppermelt up until the 6th shot. THen it went to 3 patches. At 10 shots, I started shooting 5 shots and cleaning and it dropped to 2 patches.
WHen I got to the 25 shot through her, I shot 25 more and cleaned. Still two patches and both just black then gray. Absolutely no more blue patches came out after the 10th shot!!
There was one little spot right out at the end that held copper until the 10 shot and then it went away. 7mmrhb stood there and watched the spot get smaller and smaller with every stroke of Coppermelt until it was gone several seconds later.
I haven't had the spot leave copper now in 145 shots.
Breakin took a total of 2 hours and 50 minutes. Fireforming took two days and finished it up today.
The Carbon wrap did it's job perfectly. I could feel the chamber area was body temp and the carbon in front of the end of the stock was much warmer. It dissipated the farther out I felt. It seemed that the carbon was sucking the heat right out of the chamber! Very cool!
Idaho Preacher has a thermal imaging camera that tells exactly how hot something is just by looking at it. He will look at my barrel next month. Can't wait.
The muzzle brake is a custom Titanium brake that Mike D at ABS makes. It is very effective. I was hip shooting a lot of the fireforming loads with no pain or discomfort. I would say it makes it kick like a 30-06 or less.
MOre info coming tomorrow....
