Hi Guys,
I made up some loads for the 7 mm Rolling block & had a chance to shoot it today! I necked up the brass to 30 cal. & back to 7 mm Fits like a glove! I used "The Load" of 10 grains of Bullseye with a 156 gr gas checked bullet.
Fired three rounds. No pressure sign or set back of the primer. Actually hit the target low but grouped well.
Here is my function issue!
With the fourth round the hammer dropped but did not fire. Cocked the hammer back as normal. The rolling block would not move!
A few light taps with a wood block - opened it.... BUT.... not quite all the way.
Could not remove the loaded case, as the rear of the case hit the rolling block.
The extractor did not rip the case but it was outside the case! Itied the hammer back & came home knocked out the case with no problem. I tried the rifle with a primed case it fired correctly & ejected properly! Did I not cock the rolling block back correctly? So the extractor was not returned to it's proper pre fired place?
No fun haveing a loaded chamber & a jammed 105 year old rifle, any help is welcome!
Best, broom
