Seemed up some reference data, velocity and pressures appeared quite conservative. So Blindly bought sixteen#s, and looks like I received the gamble, looks like those who attempted it Believe its a decent powder.
How can IMR Focus on be described as a concentrate on grade powder which has a starting up velocity of 900 fps! When you mentioned over, most focus on grade masses develop velocities down below 800 fps. As I originally mentioned, I are endeavoring to like Get 244 nevertheless the velocities are merely much too higher in the released bare minimum velocities.
I comprehend nobody is probably about to want to answer that in print and I might have asked Hodgdon straight, but I do the job with enough attorneys to know what their reply will be.
Burn up fee chart has little to nothing to accomplish with functionality in a cartridge. A "bomb" examination is completed inside of a closed chamber to file strain .
You probably are way too tightly specifying (clicking a lot of selection boxes) for a hull/primer/shot body weight mixture that Hodgdon didn't examination with 244 powder.
Insert to estimate Only exhibit this person #two · Jan nine, 2022 Challenge with earn powder, Is about the time most think of a favourite load for the ability/it gains a pursuing, Acquire will discontinue the ability and come up with something else. Imagine 452AA back inside the day that experienced an enormous next.
When pressures drop to 10k psi or less, all the duration of the case will get sooty when fired, which implies a bad seal. As brass get the job done hardens (nearly 4 situations fired) it will require much more strain to obtain a good chamber seal. 15k psi chamber strain will nevertheless make brass extend to obtain a good seal It doesn't matter how often times the brass has long been fired. With all that said, when chamber pressures drops underneath 15k psi, you will not get an excellent powder burn off and you might not get a great chamber seal …. both equally resulting in sooty circumstances and a little something lower than stellar effectiveness.

Who understands. We’re constantly instructed that primer condition isn’t an excellent indicator of psi but Except there is a lab it’s what we received. I have a revolver that with even least masses, mashes the primer almost into the lettering within the brass, so there’s that. If the load is effective superior, is accurate and Protected that’s everything issues.
Posted May possibly thirty, 2022 On five/28/2022 at 9:35 AM, Youngeyes explained: Are you presently indicating there are scratches are on the beech facial area, and were transferred into the primer? They look like gouges to me. Were there any other primers that appeared this way? Did you chrono the masses? I also located an report about 244. Indeed, in case you seem closely at the case on the remaining from the 12 o'clock place you are able to see exactly the same scratches but they're much a lot less pronounced. While I have a chronograph, I didn't utilize it for this operate for the reason that I was at a public vary and build is actually a PITA. Many thanks for publishing the Handloader website link. Pretty content that their five.five grain submit corresponds well with my five.four acquiring. Farmer's publish is attention-grabbing. I browse just yesterday a couple of fellow who was experiencing a concern having a load he had applied for years. He out of the blue started off having a specific brand (sorry I do not remember which) display indicators of extreme stress so he despatched a number of the cases in Winchester 244 powder reloading data the journal author for examination.
A flattened ball powder. When its Winchester its identified as "ball" instead of spherical, simply because Winchester owns the phrase "ball".
380 masses about 100fps a lot quicker. I didn’t know 244 even existed! Thanks upfront. I have a substantial amount of TG, but will need extra powder Within the up coming thirty day period or so.
Besides, I just claimed I wouldn't shoot it to get a lure load. I however wouldn't. What is the big deal?
