I might Assume in the majority of situations the temperature on the ammunition is the same at that of the rifle and scope.
) Patrick didn’t commit time endeavoring to tune a load, simply because actually we ended up endeavoring to maintain the load since the fastened variable and also the temperature given that the unbiased variable. I’d bet the outcome would look very comparable regarding muzzle velocity unfold, even if you tuned Every load. The teams could glance distinct, but I just wager the muzzle velocity spread at different temperatures may not range Substantially. So I’m not enthusiastic about shelling out time digging further into it … But I’ve definitely been amazed in advance of! In case you’d want to run by way of that, I’d be really interested to listen to what you find!

Yeah, Rick it seems like we think a lot alike! I do shoot at temperatures that are distinct than I zeroed, Though I Look at my zero really frequently … so I suppose that boundaries that to a point. I mainly shoot at 55-ninety five degrees 90% of some time, but Once i’m hunting that would be as low as ten degrees or in a summer months-time match, I might shoot in temps as higher as 105.
Many thanks, R700. Seems like pretty much as good of an evidence as I’ve heard. Unquestionably suits my practical experience. With a facet Be aware, I do use H4350 in my 22″ 6.five Creedmoor and I love the final results I’m having. But I don’t doubt that I'd be capable of squeeze a little bit more muzzle velocity from A further powder. I do know a lot of guys chase that past very little bit of muzzle velocity, but People 25 or fifty fps bumps have practically no effect on hit chance In terms of prolonged selection targets.
but after you are outside of that spot if gains and looses speed. Testing reveals matters ar enot linear For numerous powders , some have specified temp ranges the place nothing A great deal happens after which a steep drop or climb ,you may avrage that but its not real.
I’ve been at matches the place You begin off shooting in fifty° temperature in the early morning, and also the working day imr 7977 in stock heats up to Nearly ninety° by mid-afternoon. When you've got temperature swings like that, the muzzle velocity within your bullet could enhance by fifty fps or even more … which might be plenty of to absolutely skip a target.

I feel I am going to stick with my 66.forty grain IMR 7828SSC load and plug the temperature variances into the Used Ballistics app. That load is providing my just a little more than 2900 fps and sub MOA teams. I suppose that falls underneath the "if it imr enduron powders ain't broke Really don't resolve it" class.
They’re my Major audience, And that i try to condition the information for them, and perhaps incorporate a couple nuggets in there for the more advanced group (like In this particular publish, I pointed out the non-linear connection and brought up the problem about primer balance). Even though I do try to use seem tests solutions that could satisfy most professional scientists, eventually, I’m not attempting to compose whitepapers that may only be recognized with the engineers amongst us. That’s enjoyment for me, nevertheless it just restrictions the value you incorporate to the capturing community as a whole. So I always endeavor to present the outcome in a means even a amateur could recognize. Hope that is smart. Sorry IMR 7977 to the prolonged-winded reaction. Your level is a superb a person, and you also of course put considered into it … so I just wanted to try out to help you recognize my check out Once i’m crafting this sort of content.
Good work Cal. Could you explain to me when you experienced 100% powder melt away while in the 22″ barrel? Also was the speed based on the Lab radar and verified with Magnedo, or average of both equally.
