Bryan specially cited Hodgdon Extreme Series powders as one of many minimum temperature sensitive powders he’d used. He also created it distinct that no powder is totally insensitive to temperature.

As well as the velocity was averaged between the two chronographs. There isn't any way we could know needless to say which 1 was proper, Hence the safest bet was only to normal them. They ended up really, very shut … so it didn’t really make a difference Significantly.

But also the short article, did you men shoot the ammo when they were nonetheless in their temperature extremes, or allow them to settle right down to ambient?

Hello. I locate all your posts pretty usuful and related. Are you able to give us an even better indication of how the Magneto Velocity chronograph measured up on the doppler radar?

WARNING: This product can expose you to Lead, which is known towards the Point out of California to cause most cancers and start defects or other reproductive harm. For more information go to – .

I’m just entering into aggressive capturing six.5 CM within an RPR) and I’ve picked out H4350 many months in the past following looking at all of the investigate I could find on its temperature security.

If there was likely to be an accuracy difficulty Using these powders as the temperature improved, it would have been revealed.

This can be why just investigating the magnitude of the primary difference should be taken having a enormous grain of salt Except the stats are there to assistance the conclusion that they're unique and standard error bars describes it far better than my very long winded description.



A minimum of with the powders examined the variation of the muzzle velocity SD with temperature was only some fps. Hence not variable for most, if not all functions. Generally excellent to 4451 show a potential variable into a relentless. Completely have an understanding of your methodology did not allow shooting for precision.

Furthermore you’ll get to satisfy some other people who find themselves into these things, and perhaps even create a couple pals that can help you alongside.

3 – Barrel – barrel density, duration and bore diameter from thermal expansion/contraction. In combination with density, temperature would also influence the barrel bulk and shear moduli and jointly these three components figure out the probable barrel harmonics. Which harmonics are fired up relies on ammunition.

You guess! I just bought an annealer, and severely wish I might have browse it just before I built that buy. Keep out man! Glad the timing labored out better to suit your needs than for me!

Yeah, Rick it looks as if we think a good deal alike! I do shoot at temperatures which are diverse than I zeroed, although I Check out my zero really often … so I suppose that restrictions that to a point. I primarily shoot at fifty five-ninety five levels 90% of enough time, but imr 4451 Once i’m looking that may be as little as ten levels or at a summertime-time match, I'd shoot in temps as higher as a hundred and five.

I will Observe that the H4350 hundreds in my examination experienced a median SD of 6 fps! The Varget load also had only one digit SD.
