Winchester Supreme .270 Winchester cartridges measured only .003 inch shorter from the case head confront on the datum line to the shoulder as compared to fired Winchester cartridges.
) Patrick didn’t shell out time attempting to tune a load, simply because seriously we have been seeking to hold the load given that the fixed variable as well as temperature as the unbiased variable. I’d bet the results would look pretty related with regards to muzzle velocity spread, Even though you tuned Every single load. The teams could possibly glance distinctive, but I just bet the muzzle velocity unfold at unique temperatures might not differ Substantially. So I’m not serious about shelling out time digging further into it … But I’ve absolutely been surprised prior to! In case you’d want to operate via that, I’d be very interested to hear what you discover!
And it can be hard to find. Incredibly hard to find. I truly went on Gunbroker.com prior to I printed this to try to discover if there was any out there, for the reason that I figured this write-up could exasperate the challenge far more.
The spreads in cost pounds are pretty near. If loading a minimum amount degree of these powders to assemble apply masses, I would dump the powder appropriate into cases. Though with powder costs close to highest, I set my measure a number of grains gentle in the meant fat, drop the powder onto a scale and dribble in the final little bit to bring it as much as the right body weight.
The main characteristics on the Enduron collection are copper fouling eliminator, insensitivity to temperature adjustments, great loading density and getting eco-friendly.
Which is just what exactly we had been wanting to do here, And that i couldn’t agree extra. I do ponder how Those people newer powders would do, but I assume I’m skeptical in Alliant’s high quality at this time. But, it’d be attention-grabbing to find out the info!

Fascinating notion, but I’m undecided it has a measurable effect within the temperatures we’re talking about. Bolt action barrels just don’t get near as scorching as other barrels. I measured them in my barrel examination, and it amazed me which they didn’t get hotter than they are doing.
Wow. Thank you so much for sharing some details on one other powders. That actually assists put these ends in context on the bigger image. And that’s fascinating about the N140. I assume that corroborates what I found linked to the adjust in muzzle velocity not being linear with temperature change. I concur that you simply shouldn’t just take the normal.
So Actually, the number of temperatures the thing is With this powder take a look at possibly signify the intense number of temperatures you’d working experience in your situation you explained. I’d think about that Even though you left the spherical inside of a chamber that started off out at 149° F, the gun powder would probably by no means warmth up much more than the imr enduron powders one hundred forty° F … because barrels begin to interesting relatively quickly.
