During this occasion, although the cases ended up mixed, everything else was diligently monitored to get as consistent as is possible. I believe a slight blurriness or lights within the Picture is creating the remaining case to glance significantly less rounded. Actually, They may be nearly indistinguishable in that regard.
How can IMR Goal be described as a concentrate on grade powder having a commencing velocity of 900 fps! As you mentioned earlier mentioned, most concentrate on quality masses deliver velocities down below 800 fps. As I at first claimed, I are actually attempting to like Acquire 244 although the velocities are only way too significant in the printed minimum velocities.
Around the "clean burning" problem …. almost all powders have to have at least 15k psi to secure a good clean burn. A thoroughly clean burn up signifies the powder is efficient for the cartridge and bullet excess weight nevertheless it isn't going to constantly indicate it is considered the most correct load. If you find yourself working with cartridges that has a very low SAAMI max tension for instance 38 Exclusive (17k psi), 44 Unique (fifteen.5k psi) or forty five Colt (14k psi) that were designed for black powder, that you are by now with the minimal stop from the tension selection ….
Burn charge chart has hardly any to nothing to complete with general performance inside a cartridge. A "bomb" examination is completed in a very shut chamber to history tension .
You probably are far too tightly specifying (clicking too many variety bins) for just a hull/primer/shot weight mix that Hodgdon did not check with 244 powder.
The expended brass scenarios glimpse Virtually completely new within. But a huge Portion of That may be the direct-free primers, and I don't Feel we can buy People as reloading parts nonetheless.
My ramblings are things I have tried or skilled. You might or might not want to emulate them so read them with this in your mind.
The author established each of the primer flash holes had been considerably around sized, As a result expanding the force. I'm not stating that was the lead to in Farmer's illustration. Instead there are numerous things which can affect pressure Aside from the powder charge alone. In Farmer's case in point, it could be a number of items: as mentioned an over measurement flash hole, a loose primer pocket, a deep seated bullet (both at loading or from setback), or simply a variance in bullet excess weight, or case ability. Or a mix of more than one of the described things. Wolfe publishing manufactured a fascinating e-book titled Firearm Tension Elements that provide attention-grabbing reading through on The subject. My duplicate is dated 1990 and was updated in 2006 but has given that been discontinued. It really is readily available on Amazon but outrageously priced.
Insert to quotation Only demonstrate this person #eleven · Nov eleven, 2018 243winxb, Of course, brass enlargement is another reason for greater chamber pressures but it is undoubtedly not the main reason …. It is powder burn. The figures you utilised really do not have Significantly to accomplish with brass expanding to seal in a chamber …. they have got far more to accomplish with stretching the duration. Straight wall brass situations …. even magnum instances almost never extend in length when fired and reloaded ten instances or more. Annealed (smooth) brass circumstances will expand to seal in a very chamber with about 10~12k psi chamber force.
I guess that what I more info used to be trying to figure out is if the released starting velocities for these new powders was set on account of a Actual physical limitation of your powder or if it was set by an attorney.
Precision is simply great. 1535 FPS from ninety grain bullet, go think about the primer higher than. That load is to this point above any recommended load. We do not recommend any load bigger than company maximums. What will work for us, may well not give you the results you want and be hazardous.
Posted May 30, 2022 On 5/28/2022 at 9:35 AM, Youngeyes stated: Do you think you're expressing there are scratches are on your own beech deal with, and ended up transferred into the primer? They appear to be gouges to me. Were being there some other primers that appeared this way? Did you chrono the hundreds? I also uncovered an article about 244. Sure, should you search closely at the case to the still left inside the twelve o'clock placement it is possible to see precisely the same scratches but they are much much less pronounced. Even though I have a chronograph, I did not use it for this run for the reason that I had been at a public assortment and create is really a PITA. Many thanks for submitting the Handloader hyperlink. Pretty joyful that their 5.five grain article corresponds very well with my 5.4 acquiring. Farmer's write-up is interesting. I examine just yesterday a couple of fellow who was experiencing a difficulty using a load he experienced utilised For many years. He quickly commenced getting a certain brand (sorry I do not try to remember which) exhibit indicators of utmost pressure so he despatched some of the scenarios into the magazine author for assessment.
This is not your grandpa's muzzleloading procedure. Federal has created a safer, less difficult plus much more trusted solution to shoot a muzzleloader.
That is an more mature thread, you might not get a response, and could be reviving an previous thread. You should consider creating a new thread.
Are you currently chronographing your hundreds or checking out a guide that may be employing a longer barrel than you have got for data. Its in essence a different enhanced 231, also I am sure more cost-effective . Will take up less area than 231, IRRC probably about the same as tightgroup.
