Luger Heavy Barrel Not Cycling

[John Sabato]

Thanks for including your blueprint... such details will assist others with similar aspirations of rebarreling their shooters...

I know of no other ammo available in the USA in 30 Luger but the Winchester and Fiocchi. Their power factors/velocities are well within range of error for either brand.

I feel that the modern 30 Luger ammo is down loaded somewhat to be sure not to explode any of the antique handguns using it.....like they do for 45 Long Colt ammo here in the USA. I have no way of knowing what the original muzzle velocities and power factors actually were out of a 4 in bbl, and the chamber pressures that they produced.

My pleasure! You blueprint CD, which I bought from you way back in October of 2010, was of immense help to my efforts. All the information for the threading and breech work was taken from your prints.

I do have more blueprints for the receiver support block and the action wrench if anyone is interested, plus a number of other prints relating to other parts and modifications. I have designed, though not yet machined and proven, a sight base to allow the installation of either a Micro sight or Bowen Classic Arms Ruger Flat-top rear sight for the toggle. If anyone is interested in any of this stuff I can either share it via PM or make a thread dedicated to the information.

I'd be interested...I like to wallpaper the walls of my shop with prints...

Instruments(depth mic and outside mic) are your best friends, they will tell you the measurements directly without interpretations.

It bears repeating that the German/Metric system does not readily translate to 'Yankee'/inch conventions...Example - 75% thread depth; round/flat thread peaks/valleys; thread angle; Metric/Yankee allowances/tolerances; etc...

The best blueprint is the part itself...
