Otto,
I feel pretty foolish giving advice about your rifle, you know as much as I,in general, and much more about this rifle, in particular.If you can't increase the weight, I can see where you would be perplexed.While it will seen counter intuitive, another problem I worked out may help.I built up a wildcat on a new Anschutz(?)centerfire action that had never had a barrel installed, therefore the firing pin had never been tested.After doing all the work to fit up and chamber the barrel, it wouldn't fire.I finally noticed that the firing pin protruded about .100". I cut it back to about .060", and didn't have any more problems, except with CCI 41 primers, which are extra hard.My theory(which may be wrong)was that the long tip stopped the firing pin from moving far enough to build up enough speed to generate the force to ignite the primer.These things are always hard to"figure out", and when you do, you think "why didn't I see that?". Are you ready to let it go yet? BTW the fixture seems like a very good idea.
Mike
