My ramblings are items I've tried using or skilled. You may or may not want to emulate them so examine them with this in your mind.
To the "clean burning" situation …. nearly all powders involve no less than 15k psi to secure a good cleanse burn up. A cleanse melt away indicates the powder is effective to the cartridge and bullet fat nevertheless it will not generally necessarily mean it is the most exact load. When you are coping with cartridges using a very low SAAMI max tension for instance 38 Particular (17k psi), 44 Specific (fifteen.5k psi) or 45 Colt (14k psi) that were designed for black powder, you are previously with the lower close in the stress variety ….
My measured velocities were close to revealed data. For many of the cartridges I examined, W244 created a lot of the larger velocities One of the powders outlined on Hodgdon’s Web-site, and it did this with pretty very low charge weights.
You almost certainly are far too tightly specifying (clicking too many collection containers) for just a hull/primer/shot excess weight mixture that Hodgdon did not take a look at with 244 powder.
claimed: Even though I have a chronograph, I didn't utilize it for this operate mainly because I was in a public range and build can be a PITA. I'd that trouble so I bought a Labradar. Expensive as hell but perfectly worthwhile just for the ease of use. No establishing down range.
Observe I did not say "maximum velocity" since there are many periods when much less velocity is more desirable. Simply a slight change within the powder's burn price might make a noteworthy difference in efficiency.
The author decided all of the primer flash holes have been significantly in excess of sized, Hence growing the pressure. I am not stating which was the induce in Farmer's instance. Instead there are several things which can affect strain Apart from the powder charge by itself. In Farmer's example, it may be many issues: as said an more than sizing flash gap, a loose primer pocket, a deep seated bullet (possibly at loading or from setback), or maybe a variance in bullet weight, or situation ability. Or a combination of more than one on the pointed out objects. Wolfe publishing generated a fascinating ebook titled Firearm Pressure Elements that deliver fascinating studying on The subject. My copy is dated 1990 and was up-to-date in 2006 but has because been discontinued. It can be offered on Amazon but outrageously priced.
Increase to quotation Only demonstrate this user #eleven · Nov eleven, 2018 243winxb, Sure, brass enlargement is another excuse for increased chamber pressures but it is certainly not the primary rationale …. It can be powder burn up. The quantities you applied genuinely don't have Substantially to perform with brass expanding to seal in a very chamber …. they have more to do with stretching the duration. Straight wall brass circumstances …. even magnum conditions not often stretch in size when fired and reloaded ten moments or maybe more. Annealed (tender) brass cases will expand to seal in a very chamber with about 10~12k psi chamber force.
I guess that what I used to be hoping to determine is whether the printed setting up velocities for these new powders was set on account of a Actual physical limitation from the powder or if it was set by a lawyer.
Precision is just wonderful. 1535 FPS from ninety grain bullet, go consider the primer earlier mentioned. That load is thus far higher than any proposed load. We do not endorse any load bigger than company maximums. What is effective for us, may well not give you the results you want and be hazardous.

They appear to be gouges to me. Were being there another primers that appeared this way? Did you chrono the masses? I also located an report about 244. Of course, when you seem carefully at the case around the remaining during the twelve o'clock placement it is possible to see precisely the same scratches but they're much fewer pronounced. Whilst I've a chronograph, I did not use it for this operate due to the fact I was in a community assortment and setup is a PITA. Many thanks for submitting the Handloader link. Really content that their 5.five grain submit corresponds well with my five.4 acquiring. Farmer's put up is fascinating. I browse just yesterday a couple of fellow who was encountering a difficulty using a load he experienced employed For many years. He instantly commenced having a certain brand (sorry I don't remember which) exhibit indicators of maximum pressure so he sent many of the circumstances in the journal writer for evaluation.
The 244 powder definitely contains a slower burn charge. You will discover not lots of powders considerably quicker than TG. Sorry for throwing that in the way I did. Gotcha, thanks.
That is certainly why severe loaders who test a whole lot of various powders Possess a big variety of bushings. So, you purchase a bushing. Not conclusion of globe periods.
During the .forty S&W with its comparatively little circumstance ability, I saw the regularity alluded to previously with an Extraordinary velocity unfold of one fps. Teams at 25 yards weren't that click here little but were being rather satisfactory. The bullet made use of was the Sierra one hundred eighty-grain hollowpoint.
