Bryan exclusively cited Hodgdon Excessive Collection powders as one of the least temperature sensitive powders he’d made use of. He also produced it obvious that no powder is totally insensitive to temperature.
I brought a box of the Hornady Precision Hunter ammo Along with the 145gr ELDX together to view how they conduct likewise. 2790fps (2970 advertised on box)was what I recorded for 5 pictures and precision wasn't that great either. 2nd caliber that i've bought and my rifles don't like.
Potentially significant concern is the amount of photographs to have great figures. Establishing the 100yd precision is yet another subject. Typical wisdom says after Have a very specific team centering It is just a bit of cake. I'm not so particular but may just be my ignorance. An in depth description of your respective methodology to establish 100yd precision with pictures will be a boon to me. Second most effective can be your recommendation of references. Several, lots of thanks to the time and effort to complete the experiments and comment on my and also other posts.
The truth is, I even shoot extensive array and possess the LabRadar setup beside me. That’s Specially useful after you’re truing ballistics, because you know what the precise muzzle velocity was for that bullet and fall. When you've got a extremely very good rangefinder, you can do a extremely excellent drop check (not less than pretty much as good as possible for the drop test). Bryan Litz has outlined he’s also been quite impressed with it, While he hasn’t revealed any test final results still.
Loading density is ideal for magnums, nicely filling the situation at most fees, contributing to fantastic uniformity and precision. The 7mm Remington Magnum “never had it so fantastic”!
You happen to be clearly getting great velocity and precision. I would concur that there is little motive to jettison what you've got with the newer powder.
Boise, Idaho Any individual performed with either of those? Both of those appear to be pretty temp steady and appears being much easier to obtain than H1000 whilst also offering a little extra speed.
I did not get single digit SD’s with both imr enduron powders IMR powders, but they were nonetheless respectable. I’m sure I could fantastic tune the hundreds for any of these powders and obtain superb benefits.
but after you are outside of that spot if gains and looses velocity. Tests reveals factors ar enot linear For numerous powders , some have certain temp ranges in which very little Considerably happens and imr 7977 in stock afterwards a steep fall or climb ,you might avrage that but its not genuine.
Now Enable’s run that same specific state of affairs with the muzzle velocities we obtained for by far the most temperature stable powder, H4350.
At a hundred and five% fill APB is ninety five% but compressed hundreds may cause seating issues. H4831SC isn't a great powder to the one hundred thirty VLD and will be far better that has a heavier bullet while in the CM. And generally compressed hundreds do not get a complete burn up. How repeatedly in very low gentle Have you ever witnessed a substantial muzzle flash? Quite common in pistols and SB AR’s – powder burning immediately after bullet has exited muzzle – not a complete burn. You would like a complete burn off before the bullet exits if possible.
In order to avoid that state of affairs, when using a temperature sensitive powder the intelligent decision will be to load down which means you’ll continue to be throughout the choice of Safe and sound pressures even when the temperature rises. But once you do this, it possible eliminates any muzzle velocity advantage These powders might have presented about the ones that are specifically formulated to become temperature stable.
So it’s tricky to draw major conclusions from your experiments without Those people. Think about if the all the pictures During this submit disappeared. Definitely the “meat” of the effects are in my graphics, so that might erode much of the good thing about my article. I attempted to obtain the original analysis paper to no avail.
Hey, I loved the Oehler 35p. I was it’s most significant supporter. But in my imr enduron powders watch, the day and age of the light-based chronograph are above … at least for me. The LabRadar is the ultimate solution in my opinion (a minimum of for customer/prosumer options underneath $1k). It is possible to practically established it up and be all set to shoot in under 30 seconds, and I think it’s quite possibly the most precise gadget. It doesn’t affect barrel harmonics such as the MagnetoSpeed, so that means you could report muzzle velocities and shoot for groups or do load enhancement simultaneously.
