I called Alliant asking about Reloder 16

[QED]

PRS is cool and all, but it was a rl16 thread. I was already recommending substitutes for an unavailable powder.

A good, workable powder in stock beats a better powder you can't find. Sometimes the in stock one surprises you anyway.

We don't disagree. In my penultimate sentence in my immediately above post, I said the same thing.

Where I see temperature sensitivity is when I get to the site, and make that first shot. Getting a hit on a cold bore first shot is always a challenge. It doesnt matter if its winter or summer, in the desert or the mountains, 0 or 20 mphs winds. Getting a hit on the first shot is a personal goal. I get a kick out of it. I dont always get it. After which, I can pack up and go home lol If I come home with an empty MTM case, I wasnt very good that day, hahahaha

Your coldbore shot has nothing to do with powder temperature sensitivity.
If you want to do better on coldbore shots, pull a bore snake through the gun just before your coldbore shot or pull over on the side of the road on the way to the range and send a round through the barrel.

The reason coldbore shots are so different is because of the week or more of oxidization and moisture that has been gathered in the fouling that's in the barrel.

I mentioned cold bore to emphasize the first shot. When I’ve made shots using Reloder 16 on my bolt action, the ambient temp can be anywhere from 35 to 105 degrees in different times of the year. As you know, once youve made that first shot, you can generally see if your shooting high or low for that specific instance.

I agree with your points on cold bore.

I called Alliant asking about Reloder 16. I havent seen the stuff on shelves in over a year.

They said they never stopped producing. That production remains the same, and that demand is just outpacing supply.

That sucks. It doesn't look like I'm gonna see that powder soon.

There is no relief in sight. I'm down to my last 8 pound jug

That is a strange response from them. The truth is Alliant does not make any smokeless powder. St. Marks makes all the powder that is made in the USA.

It is all made by General Dynamics (U.S. defense contractor) - Who owns: the St. Marks Powder plant in Crawfordville Florida The powder from St Marks is packed and labeled under the names you are familiar with.

Some powders are made over seas and rebranded once improted. See post #14 for the whole story:

You should not be shooting high or low on your first shot if you are adjusting to the weather conditions of the moment.
If you are shooting high or low, it sounds like you are not accounting for the weather conditions and adjusting as required to negate them.
In that case, you are shooting blindly.

Part of adjusting for weather conditions is also knowing your velocity at different temperatures.
I setup my ballistic calculator's profile to do this for me automatically so I don't have to worry about it.

Do you have a handheld weather station?
It's important to record your weather conditions throughout the day when you log your elevation data throughout the day so you can lookup that information in the future.
Having hard DOPE will make you much more successful on the first shot.
You should be able to adjust for your first shot based on DOPE and your handheld weather meter to help you decide which DOPE to use.

Do you know what DOPE means in shooting?

From that last post, I dont disagree with you. You say it your way, Im more self taught and probably dont use the right terminology. I have a ballistic computer that takes weather readings. On my dope book, I can see the variances in elevation at the same range correlated to the temperature during different times and temps.

Where I shoot normally, early morning till noon, its not surprising to see a 30 degree swing in the summer.

I also shoot A2520. I feel that is quite sensitive to temp swings intraday, I can observe it more noticeably, which I can generally compensate using my reticle. On that first shot, I will do the whole ritual of taking all the readings I need. I will update through the day as needed.

Setup velocity/temperature correlation in your ballistic calculator.
If your ballistic calculator won't do that, get one that will such as Ballistic or Shooter.
Test your velocity at two temperatures 30-40 degrees apart to figure out your FPS/Degree variation and then set that into your ballistic calculator so that as you update your temperature throughout the day, the ballistic calculator is recalculating the velocity as well.

The ballistic calculator will completely eliminate your velocity/temperature problems when setup properly.

Natchez has some of Reloder 16 too. One-pound bottles still available … the 8-pound jugs sold out earlier today.

To be clear, you are correct about rifle powder. Shotgun and pistol powder is made at the Alliant facility on the Radford arsenal.
The irony is that I live 10 miles from there, but I haven't seen a bottle of Alliant powder in over a year.
