yesterday I went shooting the gun and had time to experiment. It was very hot in the weather and shooting the rifle made the barrels blistering..
Just before my first shots .
Here the target. I tried at 25 paces offhand first to see if the gun was within minut-of-barndoor.
My very two first shots was on the left target. The last two shot then went right..printing too much to the left. Bare in mind that thisis the first time I actually got this thing going..
After four shots I couldn´t hold unto the barrels.
My load was 70grain Vithavouri 130 + 16mm backerrod as filler. Bullet was 505grain solid and 480grain hollowpoint. Velocity Vo= 532 m/sec regardsless of bullet weight.The shot-to-shot variation was only 7 m/sec(23ft/sec)from both barrels. So the barrels seems to be equal perfect.
Moving on to 80 paces with a 445grain solid my two shots went a little high. I was using shootingstics and rested the rifle directly on the sticks:
The bertram brass I am using is very soft. Some cases couldn`t hold on to the leadbullet and therefore were a Little loose. The RCBS dies I was using squeezes the neck soo much I thought it was meant to shoot .475cal bullets.
I will be ordering Horneber cases and may order a new set of dies. The most importing thing is this that this rifle has potential.
Another good H&H.500express join in too..
We later tried at 100meters shooting prone and offhand. The rifle made handspread Groups to the left of aiming point. I also had one shot printing 4 feet down just 2 inch above the dirt. I suspect such a low velocity because pressure couldn´t build up right..Again due to too soft cases that wouldn´t hold tight onto the bullet.
