Each and every shot had 45 seconds of rest ahead of the next a person. Shots were being fired straight away when they hit the chamber. Practically as quickly as I could pull cause.
IMR 4166 – This powder has quite very similar burning properties to Hodgdon Varget, and can be used in the same assortment of calibers. The excellent news is this powder is a snap to uncover and looked as if it would have good brings about my examination.
Some powders ‘cheat’ ,earning and immpresion of steadiness with a particular flat line band. Vihtavouri N140 is one particular these powder its lifeless steady in 18-23°C temperature assortment ,which addresses temps Considerably in the yr in central Europe .
So I might think about they appeared and attempted hard to find A different position to make it and arrived up empty. Thus, they'd to discontinue it. It's a shame.
Many thanks with the screening, I take advantage of H-1000 lots, I ponder if it is just as secure as it’s also a Hodgedon Serious powder. Terrific report
I am aware copper bullets are extended but dang I might have essential a fall tube to really make it do the job to obtain to even close to max load. Photographs confirmed higher pressure early on inside a rifle that usually likes the sting of max.
A fast note on the comment you produced about H4350 and Varget. The rifle used had a 22″ barrel and this is why the velocities with Varget were being higher than that with H4350. Varget has the optimal burn off fee for that barrel size. H4350 is healthier with 24-26″ barrel lengths mainly because it is slightly slower which is consequently a greater powder with the longer barrel.
It’s well worth noting that in this situation Varget is about 2 times as stable as The remainder, who consequently are practically equal. Just an observation. Many thanks again for an awesome weblog. IMR 7977 Christian
. What you would probably figure out intending to your local range. I desire the all-inclusive time period weapon method. One of many accuracy variables is trajectory modeling for which muzzle velocity is a big aspect. To be pedantic suggest muzzle velocity is a little more to The purpose provided that all ammunition has some variation in velocity in order to only forecast the muzzle velocity of the future shot in a very statistical feeling.
It really is likely that no even further dialogue is required, through which situation we endorse beginning a IMR 7977 new thread. If nonetheless you feel your response is needed you could nonetheless do this.
one fps or 0.01 fps? Would it not alter the group precision at one hundred yards whatsoever? Wouldn't it change the SD on the muzzle imr 7977 in stock velocity at all? Visit the array by using a presented rifle, ammunition, sighting program and platform and establish the group precision at a hundred yards, necessarily mean muzzle velocity and muzzle velocity SD for your presented ambient temperature. Then all personal effects including impact of temperature on powder and any outcome as a consequence of thermal growth or change in Actual physical Homes are “involved” with your measurements. This is the typical engineering technique but degree pf applicability of success to other rifle-ammo-sight-System programs is probably very little identified at best.
That’s why I under no circumstances did a submit over it. Genuinely to reach any common truth you’d will need to check more than several numerous Every single primer and I just don’t contain the time to do this. It’s be another interesting experiment!
With the LabRadar, it’s quick to simply file just about every spherical you hearth in the assortment. So I from time to time history fifty shot strings. I rarely see a significant various in SD from 10 shots to 50 shots. They sometimes do vary (since it’s often only a sample in the populace), but to me 10 shots will be the minimal I need to draw substantial conclusions from.
(Editor's Notice: Any provided cartridge can be employed with several powders, that can typically change While using the bullet excess weight selected. Nonetheless, in various circumstances these cartridge tips, that happen to be printed around the Enduron powder labels, look Peculiar.
