The 2-Minute Rule for imr 3031 load data

For loading most stick powder, the one way I could attain consistency was to make use of a Lee excellent Powder measure to drop close to the desired body weight, then trickle The remainder.

There was just one era in my existence Once i was truely totally free. An airboat, 50 gallons of aviation fuel and a good machete. Just God and me and the Everglades.

I selected to operate up loads with IMR-3031 simply because, with that powder, I could commence with a legit posted load and rise in a method That may nicely happen accidentally in usual handloading, witnessing the progression of symptoms as tension improved.

That’s the most important thing to consider when selecting suitable components. They have to operate the gun securely and reliably before you can get started to evaluate their ballistic functionality downrange.

Anything you can see is always that to satisfy equally restricting parameters, you can find the swiftest powder to give you the lightest load. head that the velocities suppose tight bare minimum chamber plus a standardized four groove rifling with 0.0736 in² bore cross sectional spot.

I will echo Yet another poster in that it is some a soreness when place through a powder measure. But I generally underthrow the burden after which you can trickle around the desired pounds with this powder.

By deciding on continue on you validate that you've got study our data defense info and approved our general terms and conditions.

the sole cause I exploit inventory powders is for specified accuracy loads and/or lower quantity loads, so taking the time to trickle and weigh Each and every load isn’t also onerous.

we have been engineers and reloading fanatics and we run Probably the most strong ballistics calculators. study more details on us.

This is an older thread, you may not receive a response, and could be reviving an previous thread. you should contemplate creating a new thread.

Powley’s calculations may or may not be considered a in close proximity to-utmost load or, for that matter, an suitable starting load. It pays to double-Test versus any published data you could find, and in some cases then, it requires over a bit popular feeling based upon knowledge.

launched in 1916, DuPont sixteen imr 3031 load data 223 turned amongst Philip Sharpe’s favorite powders for mid-sized cartridges. He describes it as DuPont’s “pride and Pleasure” for a few years – the “most adaptable of your IMR series” and “adapted to far more different sizes and designs of cartridge and a broader array of velocities and burning pressures than something Beforehand produced.

This is often an more mature thread, you may not get a response, and will be reviving an previous thread. remember to look at creating a new thread.

 It can be excellent powder.  However, if you are Doing work up a load maintain a watch out for pressure signs.  0.2gr could make a difference between a good load and an overpressure one particular.  I also Consider the powder might be a little more temperature sensitive than a lot of the Some others I've tried using.
