Monitoring Bore Pressure 10ML-II

You may think you are being informative but you are treading on thin ice. By quoting your experimental duplex load data you have no control over what others do with that information. Duplex loads are not for general consumption and extremely dangerous. The equipment you say you use is worth @ $1000 and I guarantee you there would be nowhere near 1% of seasoned handloaders who would ever consider buying that stuff. The questions here are about "what is a good deal on a first press" not what type of equipment do I need to test the metallurgy of my gun to make sure I don't blow it up with a non proven duplex load. This why experienced loaders here always warn people to be safe. Like don't buy open cans of powder at a gun show or handloads from strangers. I have been handloading for 35 years and still have ten fingers and both eyes and intend to keep it that way. Try putting in an insurance health claim of any type after blowing yourself up and let us know how you make out. At this point you would be better off explaining to the inexperienced what a duplex load is and the possible perils/effects of making a mistake. Lot's of guys getting into it here and this is in no way helpful or responsible. Once you light up that charge and it goes "BOOM" hindsight won't reverse the possible injuries.

Like I said to Jaycee...this thread is part of a continuing series with guys who are experienced.

In fact Ed has already posted a warning, his 1st sentence, about duplex load in an earlier thread on this topic.

First off I’m not promoting for anyone to try or use a duplex powder load in a SML. As stated in another post I personally have been using a single powder load for my 10ML-II for years because it sufficiently provided what I needed for a given load. But now I find myself at a cross road where more than likely I will need to duplex for my new load parameters.

First off I have been reloading for 35+ years so what does that prove.
Besides why is hand-loading reference even appearing in the muzzle loading forum?
For the record I have used explosives in metal forming and had a license for Alberta and Saskatchewan for using explosives. I still have all my fingers, thumbs and eyesight so do you think I treat handling explosive material lightly?

So by displaying accurate pressure info on duplex loads is not helpful to others venturing in this area?
I’ve already touched on duplex load application in a previous thread if you were paying attention.

Criticize and character assassinate all you want to build your own character in front of others. I’ll stick to generating accurate info that may be helpful to others to allow them to safely navigate with some duplex loads instead of dangerously probing in the dark.

The barrel's are tested to 129,000 psi so be it 34 or 35,000 psi ? Go through this added head ache / not hunter friendly for 200 fps? Screw the added duplex stuff. But have fun continue on. That and duplex load's are easy to come by , If you can answer this page then you have the power to research I did it with in minute's just not interested.

It is not really just about more velocity. Duplex loads can improve ignition of the charge and increase burn efficiency. This isn't a new thing and has been going on ever since I bought my Savage 5 years ago. http://dougsmessageboards.proboards....-muzzleloading

Have you ever experienced an inefficient burn on ignition with smokeless powder? Have you ever experienced an ignition problem that was powder related as opposed to a defective primer or dirty vent hole? Not likely. You people are trying to solve a problem that doesn't exist. The Savage uses the same ignition components as a modern centerfire except for a shotgun primer. There is no need to reduce pressures when using tested and proven factory load data. The marginal increase in velocity isn't worth risking injury. We kill bull moose pretty well every year up to 200 yds with factory recommended loads. You are not helping people by proposing this stuff. More people have seriously hurt themselves and blown up Savages than any other modern inline. Savage Corp has dozens of active law suits against them because of "experts" who feel they can do better than Savage's multi million dollar ballistics labs that is staffed with Engineers . And let's not forget we are talking about America, the land where mothers sue their children over spilled milk. I'll side with the professionals. But hey whatever floats your boat.......

Okay you stated you weren’t interested but had to respond for what purpose?
If I wasn’t interested in something I wouldn’t even respond to it.
Answer what page?
Pray tell where duplex loads for the 50 are easy to come by?

The quoted pressure of 129,000 is for the original 10ML and not the 10ML-II which is less. You couldn’t even get that right. The pressure you should be concerned with is getting over 80,000 where barrels can be bulged or ruined without rupturing.

Your post reveals how little you actually know about the 10ML-II smokeless muzzle loader.

Who said or mentioned anything about problem solving?
Is this something you thought up?
What was mentioned was the possible positive results of using duplex over single powder loads. My how that got twisted around.

Who promoted or said anything about helping anyone with a problem. This is about choice or options for the shooter with eventual proven test results for them to see. Your comments and approach would be to deny them this choice with negative comments you presented. I give more credit to the shooter’s intelligence to decide for himself if he does or doesn’t want to use this provided info.
