Hey, Clay. That’s a huge question to attempt to deal with while in the comments, Which is the reason it took me a couple of days to compose a response. I’ll try out to assist up to I'm able to. If I had been just getting started, I’d aim significantly less on equipment (beyond a capable rifle setup like you already have) plus much more about your elementary marksmanship and understanding of lengthy-vary capturing and very best methods on using your lengthy assortment rifle.
I then employed the Prometheus Gen II Powder Scale to toss all expenses. I've checked the Prometheus quite a few situations over a superior-conclude Sartorius analytical scale, and every time it confirms what I already know: the Prometheus is accurate right down to just one kernel of powder! The Prometheus isn’t low-cost (starts about $three,800), but in case you reload just as much as I do, it may conserve a huge amount of time, and allows me to go to the vary in place of sitting down around loading all day long.
Because the IMR Enduron powders go over the complete number of center hearth calibers, it would not be good to simply decide one powder for tests.
To determine how properly the Enduron Technological innovation reduced buildup of copper fouling in the bore, I appeared in the bore ahead of and just after taking pictures IMR-4955. The barrel was thoroughly soaked and cleaned with Gunslick’s Foaming Bore Cleaner until a Lyman Borecam Digital Borescope confirmed it was completely free of copper fouling. Images in the clean bore had been taken at 8, thirteen and 19 inches in within the muzzle. Immediately after firing twenty five cartridges loaded with IMR-4955, I mopped out the bore with citrus cleaner to get rid of powder fouling and once again took photos at the exact same 3 intervals.
I just hope more transparency will come out shortly to swatch rumors and speculation. I despatched them an electronic mail requesting clarification. I will submit in this article what I hear again, if It really is anything at all much more than a generic answer.
I attempted to trace down the short article with the charts and photographs but no accomplishment. The post appeared on An additional web page imr 7977 in stock but additionally with neither charts nor pics. With any luck , an individual will see them. Granted the methodology generally speaking was fantastic the inescapable summary is the fact zero and on the rifle-scope technique recognized at at offered temperature, say ambient, will alter with temperatures clear of ambient even if the ammunition is at the ambient temperature at time of shot.
Wow, Blaine. I could certainly see a adjust of charge amongst a lot, even so the muzzle velocity happening as temperatures go up is a thing I haven’t viewed. The reasoning is bending my mind a bit. Is it possible to convey to me a little bit more about the details of any time you noticed that?
Many thanks, R700. Seems like nearly as good of an explanation as I’ve listened to. Unquestionably matches my expertise. On a aspect Observe, I do use H4350 in my 22″ six.5 Creedmoor and I really like the final results I’m having. But I don’t doubt that I might have the capacity to squeeze a bit more muzzle velocity from A different powder. I am aware many men chase that very last very little bit of muzzle velocity, but These 25 or 50 fps bumps have just about no influence on strike probability With regards to extended assortment targets.
Ha! There is yet another test I can have to head out and shoot one day. This is often absolutely a rabbit hole! The more issues you are attempting to answer, the greater thoughts you find. Nevertheless it’s lots of enjoyable. It looks like we’re nevertheless within the steam motor days of All of this, and we’re our Studying is simply accelerating.

If you are doing primers, check out Sellier & Bellot primers (at least LR). A friend turned me on to them, and they IMR 7977 took my SD down from lower teenagers to lower single digits in 6.five Creedmoor. They may be cheep and they seem to operate – i’ll have extra details just after shooting them through the remainder of the calendar year.
Initially thanks for your time and efforts and skills in undertaking the experiment and secondly in answering my query.
Patrick is becoming an excellent friend of mine (Cal, the creator of PRB), and he pointed out attempting to do a powder examination. We collaborated on some methods to approach it, and Patrick took it from there. Patrick is often a meticulous male, and he imr enduron powders put from the work on this examination. I hope you find it as fascinating as I did. Many thanks Patrick!
That’s precisely what I’ve study. There may be A further Australian powder which you’re speaking about, but that just sparked my memory.
It is actually common for velocity spreads to slender as bullet bodyweight will increase. Except for two or three circumstances, 4955 produced the very best groups from your Browning rifle. If precision and velocity of every one of the bullets tested are included collectively, IMR-4955 was the across-the-board winner for that examination rifle.
