I am betting This is exactly why the masses are rated at 15k psi or increased. This does not imply You cannot utilize a lighter powder demand however it does mean your gun, bore, and arms will get filthy.
How can IMR Goal become a focus on grade powder using a commencing velocity of 900 fps! As you noted over, most goal grade hundreds develop velocities underneath 800 fps. As I initially mentioned, I have already been attempting to like Get 244 however the velocities are just much too superior in the posted least velocities.
I comprehend nobody is most likely gonna want to answer that in print And that i would have questioned Hodgdon right, but I function with enough Lawyers to know what their respond to will be.
My calculated velocities were near to published data. For lots of the cartridges I tested, W244 developed many of the better velocities Among the many powders detailed on Hodgdon’s Web-site, and it did this with relatively lower demand weights.
You probably are way too tightly specifying (clicking a lot of range boxes) for any hull/primer/shot body weight mix that Hodgdon didn't test with 244 powder.
claimed: Though I've a chronograph, I didn't utilize it for this run mainly because I was at a general public assortment and set up can be a PITA. I'd that difficulty so I purchased a Labradar. Costly as hell but very well worth it just for the simplicity of use. No establishing down selection.
Notice I didn't say "greatest velocity" for the reason that there are numerous moments when a lot less velocity is a lot more attractive. Simply a slight improve in the powder's burn rate can make a noteworthy difference in performance.
The writer determined many of the primer flash holes ended up significantly over sized, So rising the stress. I am not declaring which was the bring about in Farmer's instance. Alternatively there are several things that can impact stress Other than the powder cost itself. In Farmer's case in point, it could be quite a few matters: as mentioned an above dimension flash gap, a loose primer pocket, a deep seated bullet (both at loading or from setback), or perhaps a variance in bullet pounds, or situation potential. Or a combination of multiple of the described items. Wolfe publishing made a fascinating book titled Firearm Strain Things that supply attention-grabbing reading through on The subject. My duplicate is dated 1990 and was updated in 2006 but has considering that been discontinued. It is really accessible on Amazon but outrageously priced.
Include to quote Only show this person #11 · Nov 11, 2018 243winxb, Certainly, brass growth is another reason for higher chamber pressures but it's surely not the main purpose …. it's powder burn off. The figures you utilized really do not have Significantly to do with brass increasing to seal inside a chamber …. they may have additional to accomplish with stretching the duration. Straight wall brass situations …. even magnum instances not often stretch in size when fired and reloaded ten moments or maybe more. Annealed (comfortable) brass cases will develop to seal inside a chamber with about ten~12k psi chamber pressure.
I assume that what I had been attempting to figure out is if the released setting up velocities for these new powders was established because of a physical limitation in the powder or if it had been set by a lawyer.
Accuracy is just good. 1535 FPS from 90 grain bullet, go look at the primer over. That load is up to now previously mentioned any advised load. We don't advise any load larger than manufacturer maximums. What functions for us, may not be just right for you and become risky.
Was speculated to be a surprise powder for medium electricity handguns taking pictures jacketed bullets. Has gotten awful assessments even for that style usage.
This is often an more mature thread, you may not get a reaction, and could be reviving an previous thread. Remember to take into account developing a new thread.
This is certainly an older thread, you may not receive a response, and could be reviving an outdated thread. Be sure to think about making a new thread.
Personally, I stick with powders that have an established here reputation and lots of load data from a number of sources. W-231 is a perfect illustration of this While W-244 is too new to look in almost any of my reloading manuals.
