The main features of your Enduron series are copper fouling eliminator, insensitivity to temperature changes, best loading density and becoming eco-friendly. Sight inside your rifle all through a heat wave, fill your tag when it’s subzero.
I then used the Prometheus Gen II Powder Scale to throw all rates. I've checked the Prometheus a number of situations on a significant-close Sartorius analytical scale, and every time it confirms what I previously know: the Prometheus is precise down to an individual kernel of powder! The Prometheus isn’t low cost (starts off about $three,800), but when you reload up to I do, it could possibly preserve a huge amount of time, and allows me to Visit the array as an alternative to sitting down about loading all day long.
Probably major issue is what number of shots to receive great stats. Establishing the 100yd precision is another make a difference. Conventional knowledge suggests after Have got a exact team centering It's a bit of cake. I'm not so particular but may just be my ignorance. An in depth description of your respective methodology to ascertain 100yd precision with photographs could be a boon to me. Second finest will be your suggestion of references. Many, many many thanks to the effort and time to do the experiments and comment on my and also other posts.
SW MT I attempted 8133 with 140 Etips in my 7mmRem. I wound up with case total and really compressed hundreds appropriate from the bat. Like very audible crunch when seating a bullet.
Loading density is ideal for magnums, nicely filling the case at utmost rates, contributing to outstanding uniformity and precision. The 7mm Remington Magnum “hardly ever had it so excellent”!
Terrific exam! its great to check out how temperature has an effect on these things. In case you have time it is best to plug within the numbers you got into your monte carlo simulator. It will exhibit the particular genuine globe affect of being off by one-2F or by not correcting with the temperature in the slightest degree!
Vaughn. I guess you might find out quite a bit from a dude like that. That may be a fascinating idea in regards to the submit-muzzle acceleration, but it surely looks as if People men could possibly have corrected for that from the application. Up coming time I see them, I’ll surely request! You’ve got me asking yourself!
I had been in the hurry, so I didn’t devote time troubleshooting them. I feel there was some interference, and I’m sure I could determine it out if I spent enough time on it. I actually have 2 buddies with them now, so I could most likely have 3 arrange side-by-aspect, and if all of them gave the identical specific examining for every shot … it seems like that will provide you with a lots of self esteem while in the output. The ultimate experiment could be to shoot three of these like that, and also shoot in excess of a twelve foot Oehler or one of the industrial-quality chronographs like Bryan has. I’d guess he does that imr enduron powders experiment at some point, and I'm able to’t wait around to browse the effects.
At the least for that powders analyzed the variation of the muzzle velocity SD with temperature was only a few fps. Consequently not variable for some, if not all purposes. Normally good to turn a possible variable into a continuing. Completely have an understanding of your methodology did not allow shooting for precision.
In actual fact, after that examination … I explained I wouldn’t ever get it out and established it up once again. Initially, imr enduron powders it’s a discomfort to set up in comparison with the others. It’s also very fickle (very poor or inconsistent lights, wind, or small specifics in set up can skew the outcomes). And it diversified up to ten fps or more from the opposite two units. I changed a sensor plus the batteries within the Oehler 35p, and in addition was meticulous in double-examining the many distances and angle from the sensors prior to the take a look at. But the readings just didn’t appear to be as consistent because the LabRadar or MagnetoSpeed. Now I used to be screening the Oehler in it’s default configuration (regular 4 foot display screen spacing, and didn’t have it in a lightweight box). If you distribute the screens to eight foot or even 12 foot, you’d be capable to Increase the functionality. At the same time, that will ensure it is even less handy.
At one hundred and five% fill APB is 95% but compressed hundreds might cause seating problems. H4831SC is just not a perfect powder with the one hundred thirty VLD and would be significantly better having a heavier bullet inside the CM. And customarily compressed loads never get a whole melt away. How repeatedly in minimal light-weight have you viewed a sizable muzzle flash? imr 7977 in stock Very common in pistols and SB AR’s – powder burning right after bullet has exited muzzle – not a whole burn off. You want a whole melt away before the bullet exits if possible.
To prevent that circumstance, when employing a temperature delicate powder the good alternative should be to load down so that you’ll continue to be in the number of safe pressures even when the temperature rises. But whenever you do that, it most likely eradicates any muzzle velocity advantage Individuals powders may have provided around the ones that are particularly formulated being temperature steady.
So it’s rough to draw important conclusions in the experiments devoid of These. Consider When the all the pictures in this put up disappeared. Definitely the “meat” of the outcomes are in my graphics, so that will erode Considerably of the good thing about my post. I attempted to obtain the original analysis paper to no avail.
7mm Rem Mag is really a Highly regarded hunting cartridge, and once and for all causes! With this particular cartridge you have far more velocity when compared to three hundred Acquire Mag, and less recoil too.
