8mm-first three shots.png
This is a photo of the first three shots from my 8mm Coyle. It was 1/4" center to center. The load consists of highly modified Lapua 7 Rem Mag brass with no belt, Hammer Hunter 198 grain, Federal 215 Magnum, H4350 @ 3,054 feet per second. Rifle weighs 7 1/4 pounds ready to go. I fired two more and #4 opened the group to 9/16" with #5 touching the first three.

So got to go and shoot my 35 Whelen today and fireform the rest of my brass. Other than pulling on the 4 th shot I’d say it shoots pretty decent. Those 35 cal bullet sure make a big hole . The bullets I’m using for fire forming are 180 Speer hot cor over a lighter charge of imr 4064 .
The group shot was shots 21-25 through the new barrel . Some more fine tuning then it’s off to the 250 gr speers . Hopefully they will shoot this good or better . This was my first real attempt at forming 30-06 brass to 35 Whelen . The brass looks good shoulders nice and crisp all measurements look good .
Can’t wait to plow a big ol doe with this sucker here in a few weeks

Shot at 200y with my Terminus/ibi 6.5cm. Berger 144hyb/h4350. The outlier in the first group was not the cold bore shot, the first shot was the highest in the cluster of 4.

Second group was partly my fault, wiffed the first one low, knew if as the shot broke. One of the ones you don’t need to look downrange for as you know it wasnt there. Also dialed in a click for wind, which proptly died right off..
