An additional matter that arrived to my intellect, that held me thinking Because the introduction in the magnetospeed:
That’s a fascinating stage, Steve. I haven’t ever listened to someone mention that prior to. I don’t claim for being an authority in metallurgy, so that might surely be the situation. And that i readily acknowledge that Like several examination, this wasn’t excellent. I read a knowledge analyst say 1 time “
ninety four% of shooters ending in the highest 100 while in the Precision Rifle Series (PRS) decide to run considered one of gun powders from your Hodgdon’s Extraordinary Number of powders, like H4350 and Varget (see the data). Although Those people powders may well not often make the fastest muzzle velocities, veteran shooters have discovered to rely on that Extreme powders will give reliable muzzle velocities throughout pretty much any setting.
The truth is, every now and then We now have witnessed an inversion of your powder temperature – muzzle velocity partnership for a particular large amount of powder where the muzzle velocity basically decreased as the powder temperature greater.
I assumed it had been a fantastic post. They went to some fantastic duration (like renting a freezer truck) to try to receive it right. Which makes it far more disheartening which the report is lacking the charts and photos. It appears like someone duplicate-and-pasted it in from A different supply and the photographs weren’t bundled.
But way too the posting, did you fellas shoot the ammo even though they had been IMR 7977 nonetheless of their temperature extremes, or let them settle all the way down to ambient?
I’m just entering into aggressive shooting 6.five CM in an RPR) and I’ve picked out H4350 many months back following examining every one of the exploration I could locate on its temperature steadiness.
I read that bench relaxation competition, if possible, load their ammunition on the day of your match. I can envision them loading IMR 7977 quite a few sets of ammunition for different temperatures so that you can obtain the 0.1 MOA precision necessary to get. Knowing their methodology in detail would be most exciting.
If you need to do primers, try out Sellier & Bellot primers (at the very least LR). A pal turned me on to them, and they took my SD down from minimal teens to low one digits in 6.5 Creedmoor. They can be cheep and they seem to operate – i’ll have far more info just after capturing them by means of the rest of the 12 months.
DuPont used to make a bunch of powder within the US, and operated like forty some amenities at 1 time, Nonetheless they had been damaged up after The federal government shut them down because of anti-trust legal guidelines to prevent the monopoly that they had.

To the awesome function, IMR 7977 I value all your awesome efforts in explaining your posts out so us inexperienced persons can Evidently have an understanding of! ….sustain The good do the job

Hey, I cherished the Oehler 35p. I had been it’s biggest admirer. But in my perspective, the day and age of the light-centered chronograph are over … no less than for me. The LabRadar is the final word Answer in my view (at the very least for shopper/prosumer options below $1k). You could basically set it up and be able to shoot in under thirty seconds, and I believe it’s by far the most accurate system. It doesn’t affect barrel harmonics like the MagnetoSpeed, so Which means you'll be able to document muzzle velocities and shoot for groups or do load improvement at the same time.
