Thanks Randall, I feel better now, of course the medication helps...
Looks like some of theses guys also want to help, the more the merrier, we're going to make history!
Randall,
These are pressure guns, I just need to figure out how to measure bolt thrust, in the 450 and any other cartridge I need, as well. I’m not sure what you mean by bring the firing pin coming in at an angle, but try again, sometimes my pea-brain farts. But, I was thinking of a sensor that looks more like a washer, with the firing pin that goes through the washer. The washer will be placed in the bolt face, right smack behind the case head face, in this fashion I can compare apples to apples or at least to an expectable standard, like for instance, what is the exact bolt thrust of the standard 5.56/223 factory and Blue-Pill fodder, compared to a high speed, modern loading, for the 450 Bushy. If I do this right, I will be able to use this particular pressure gun for my many other projects, changing barrels/calibers and were off to the races. What do you and our readers think? Seems that this has not been done or it’s a big secret, I mean, we love our little math models and they do accurately measure bolt thrust in bottle necked cartridges, but they tend to not apply to straight cases, hence, we don’t need anything else, right? Let me explain.
Since the civil war, straight cartridges and their developments were laid to waste by smaller calibers, with necked cartridge cases using smokeless powders, never fully ringing out what the big bore straight cases could actually accomplish. This work today is relatively new to our world, to which I have played no small part in its developments.
Bernoulli came up with a theorem in the late 1700’s that explained why I was seeing things that our canned little formulas, just weren’t explaining or were actually denying, what I was finding to be the opposite of what the formulas where saying should be happening. But, like the black powder 45-70 development, Bernoulli was lost in time or at least as it applies to my ballistic models. Hence the need to build a pressure gun that also measures bolt thrust. Seems positive field results, which are repeatable using the 450 Bushmaster, just aren’t enough.
Interesting note; Bernoulli had a Mentor, which was one of my Grandfathers, who also discovered a Mathematical Theorem. Actually I’ve had two Grandfathers that have Theorems, after their names.
But, I digress, common guys, what is the best way to build the definitive answer machine, the Nay-Sayers have had their say, let’s have ours? Pressure/Velocity/Accuracy guns are well understood; mine will look and function, not unlike them, with a twist for bolt thrust. Randall and I have a couple of ideas, what are yours?
Safety First..t

..Yup the sensor I propose will be piezoelectric. No locking lugs, just a bolt block, Falling Block style. I suppose I'll relieve the action for the sensor, insert the cartridge into the barrel and then, maybe something like, screw the barrel in, coming up to a tork number, so that I can keep everything, samey-samey, between the 450 and the 223 and any other cartridge I choose. Now, I'm only thinking out loud here, because the barrel in a standard pressure gun just pins in, which I could keep if I could guarantee the same exact head-space for each of the cartridges...what am I missing gents?
