..............I would like to see him offer that QRBP machined for the brass or aluminized bronze LRMP modules...........
............The last time I ordered something from Cecil..........Haven't ordered anything since.........
Me, i was just pointing out, what you wished for is available..........................I would like to see him offer that QRBP machined for the brass or aluminized bronze LRMP modules...........
I saw that the other day. I'm not loading any rifle on a live primer, even if the firing pin was removed. If i ever went with that type of system, I would make up a dummy module and paint it orange. Load on that, then replace for hunting. We have to remove the primer before transporting the rifle to be considered unloaded, so i would put the dummy in the breech plug.
For Target shooting, this would be a real PITA, so I might consider loading on the dead primer module, then replacing after the first shot.
One very nice thing about this ignition system is it is completely contained in the breech plug, and essentially removes headspace from the equation. As long as your firing pin can set of off the primer, it won't matter if your bolt face or standing breech is compressing the module, as long as it is close enough to prevent the primer cup from backing out of the module.

He offers both systems in the CVA Scout TD .45-70 rifle conversions which allows you to use the extractor on the brass/bronze modules.
He's been real busy lately, and added lots of offerings in that Hanks Precision Gun Parts site. A lot of it, like the breech plug conversions are built long and needs to be custom fitted by a Smith or DIY.
He does offer converted Scout TD .45-70 rifles in stock with either Direct or Modular ignition in a couple different package options.
Here is a proven system that does exactly what you desire.
The PR adapters are stainless steel, and are very very durable. Because the adapters are stainless, the don't 'crush', and most all the time there will be blow by. This blow by can be cured by utilizing an o-ring. The adapters are a larger diameter than shotgun primers. The primer socket in breech plugs needs to be enlarged for these adapters to fit. This can be done with a 9/32" end mill. One also uses the end mill to make the socket deeper so that one's rifle will go into battery when the o-ring is in place. Another thing done to the breech plugs was to enlarge the flash hole to 0.034". The adapters fit a 22 Hornet shell holder, so they can be easily primed, with any standard priming tool. Spent primers are easily removed in any standard press.
The large rifle magnum primers were tested in sub-zero weather more than once, and there never was a problem igniting Blackhorn powder, after the loaded rifle was left out over night. Unlike shotgun primers, the magnum large rifle primers do not erode flash holes. After 700 shots, measured flash holes were exactly the same as they were at zero shots. It seems like the adapters, and the breech plugs will last forever. ☺

So far in USA, one is free not to pursue a purchase one doesn't want.
Seems i misunderstood. You wrote Me, i was just pointing out, what you wished for is available............
It seems like not loading on a live primer is an excess of caution, especially since all the new break actions have a transfer bar that separates the hammer from the firing pin. Your primer is more likely to not fire than fire inadvertently.
I was told a while back you cant use a DI system in alloy frame rifles. I was told break actions needed a steel frame and bolt actions needed lugs. The primer in a DI system gets the full peak pressure on ignition. Thats the entire point of DI....No flash hole, vent or bushing is used.
DI creates more peak pressure and more velocity. Scat traced BH209 loads with DI but we lost those traces when he left Hanks. IIRC it was around a 10% increase vs a 209.
One of the things im curious about is the sealing surface also. The bigger one is if you only tighten the plug by hand but use a nut driver to install the module.....The whole thing might come out when you remove the fired module.

An 8200 psi pressure spread from the HIS system to my DI with .125" flame channel modules is a LOT. With the DI system that is currently marketed having a .082" flame channel and falling half way between the HIS system and my DI with the .125" flame channel pressure wise, a lot of extra testing would be required to keep everyone safe as different powders react to DI and DI flame channel volumes much differently than any other ignition system to date. In pressure testing, there are a LOT of behind-the-scenes things that go on. Each gun calibration must be confirmed before recording traces. Things happen sometimes where a trace didn't record properly, etc. All of these things add together, along with the actual traces, to use a lot of projectiles, some of which are expensive. While some are donated and very much appreciated, the cost of pressure tracing is still expensive. Therefore, I plan to change my DI module flame channel to .093" (3/32") which is much closer to the size Jeff uses. This is the only way we can do this and keep confusion to a minimum, tracing costs down, and everyone safe. I plan to trace LRMP and DI on every load because the differences can be so great depending on powder used and weight of charge. We can no longer deduct or add pressure when comparing loads with other ignition systems. We have had good luck with QL estimating pressures but DI has made QL much less accurate in predicting chamber pressures. That said, I will make modules in a few days and pressure tracing will resume.
-Jerry was making his modules out of 3/4" screws (Hank's are 1/2") Jerry bore a .125" (1/8") hole thru from the primer pocket..........Hank's has an eighty thousandths (.080") hole.
