Earlier this year, there was a PRS match in Nebraska in which rivals had to shoot within the snow, and some of the identical rivals will likely be located in Oklahoma capturing “The Heat-Stroke” match mid-July exactly where temperatures could exceed 100 levels!

The idea below was to isolate the powder as being the variable, not the complete weapon program and optics. This experiment did that rather nicely.

The velocity wasn't what i'm searching for at this point. I am seeking to be inside the 2900fps realm but at this moment Using the 60gr load I am sitting at 2843fps normal. Undecided .eight of a grain will get me considerably more velocity.

I understand references that compute barrel harmonics/vibrations and references that present the temperature dependence on the elastic constants of steel but none that explicitly compute the change of barrel harmonics/vibrations being a operate of temperature because of impact on elastic constants. A project.

It’s amusing to Consider it’s hard to determine what the “genuine” muzzle velocity is, but that is certainly what you’d have to determine to answer that problem … and it’s just not a fairly easy factor to answer.

Wow, Blaine. I could definitely see a improve of charge IMR 7977 in between lots, even so the muzzle velocity going down as temperatures go up is one area I haven’t seen. The concept is bending my thoughts a little bit. Can you notify me a bit more with regards to the specifics of after you saw that?

I’m just moving into aggressive shooting six.5 CM in an RPR) and I’ve picked H4350 various months back just after studying every one of the investigation I could obtain on its temperature stability.

I read that bench relaxation competition, if at all possible, load their ammunition around the day from the match. I can picture them loading quite a few sets of ammunition for various temperatures in order to realize the 0.1 MOA precision required to earn. Knowing their methodology intimately will be most appealing.

Your muzzle velocity WILL vary depending on ambient temperature, no matter what powder you employ. So when we will seek out to mitigate that variance … at this point, no powder lets you entirely get rid of it. But, you can lower the effect by earning a clever powder variety.

No matter whether which was due to the temperature modify or Jim's capturing, we simply cannot say. Whatever the trigger, from the hunter's perspective, accuracy imr 7977 in stock was primarily unchanged.

Here's a check out of your underlying data, which shows the normal muzzle velocity for each group of ammo:

When we headed for the assortment for any examination, we randomly chosen 20 rounds in Each and every caliber from your inventory. We chronographed the velocities that has a Caldwell Ballistic High quality chronograph working with their Android telephone app.

Truthfully, we just aren’t keen on that powder as a consequence of what we’ve professional with it regarding IMR 7977 temperature sensitivity.
