It was announced Practically a calendar year ago but hasn't still revealed up in most shops. In accordance with Hodgdon, W244 is similar to CFE pistol.
I notice no one might be likely to want to answer that in print and I would have requested Hodgdon directly, but I work with more than enough Lawyers to really know what their remedy will be.
My measured velocities have been near published data. For lots of the cartridges I analyzed, W244 created several of the bigger velocities One of the powders shown on Hodgdon’s Web-site, and it did this with pretty lower demand weights.
You probably are much too tightly specifying (clicking too many selection bins) to get a hull/primer/shot bodyweight mix that Hodgdon didn't examination with 244 powder.
Essentially the most telling indicator will be the scratches that appear so clear over the primer of your red case but are fewer distinctive to the blue situation. That may be mainly because of the excess force pushing the primer back again more durable from the breech face and so transferring the scratches that surface about the breech experience more clearly.
When pressures fall to 10k psi or considerably less, the complete duration of the case will get sooty when fired, which suggests a inadequate seal. As brass function hardens (nearly four occasions fired) it's going to take all the more pressure to get a superior chamber seal. 15k psi chamber force will however make brass grow to obtain a superior seal It doesn't matter how repeatedly the brass continues to be fired. With all that said, when chamber pressures drops down below 15k psi, you won't get a very good powder burn off and you might not get an excellent chamber seal …. both of those resulting in sooty conditions and one thing fewer than stellar efficiency.
According to the article, the granules more resemble Titegroup indicating that they're from that very same approach.
Insert to quotation Only exhibit this user #11 · Nov 11, 2018 243winxb, Indeed, brass growth is one more reason for bigger chamber pressures but it is absolutely not the principal purpose …. It is powder burn. The numbers you employed truly do not have Considerably to try and do with brass increasing to seal within a chamber …. they've more to do with stretching the length. Straight wall brass scenarios …. even magnum cases not often stretch in duration when fired and reloaded 10 times or even more. Annealed (soft) brass scenarios will increase to seal inside of a chamber with about 10~12k psi chamber force.
Powder brands do not like to listen to complaints regarding their manufacturer of powders …. particularly when a different powder is introduced as being a clear burner that helps lower bore fouling.
As is legitimate of all Winchester powders, W-244 can be a double-foundation Ball powder. Its nitroglycerin written content is 37 percent; its bulk density is .800 g/cc. A close evaluate the person granules shows them to get very irregular in shape, denoting They are check here really through the same spouse and children of powders as Hodgdon’s Titegroup. Dimensionally, 95 p.c of these must pass through a display of .0469 inch. Touted being a “Winclean” item in firm literature, the powder is pointed out to generally be clear burning, to have superb metering characteristics and to incorporate a decoppering agent.
× Precision was similar to what my guns typically shoot. Precision with most 9mm hundreds and with every one of the .45 ACP hundreds was a lot better than ordinary for my guns, suggesting that W244 has actual opportunity in handloads used for taking pictures matches.
This powder surprised us. You can in fact get some pretty superior functionality out of the for this kind of fast powder, or should really we say, "we did", While using the 90 grain bullets. We like this powder a whole lot and could well be joyful if it was all we used for range time practice, or maybe capturing steel competition.
May be well worth a try though. No Qualified techs seem to have attempted it. You will find small danger in going to lighter payloads until you start getting weak as well as squibby, or you can't obtain a wad that fills up the stack.
I have noticed people today shoot The brand new "clean" manufacturing facility ammo within the variety and it truly is stunning. Winchester SuperClean and Sellier Bellot Nontox.
