Hi all, I have a nice 16ga low pressure (6500psi & 1235fps) load with a payload of 1 1/8oz, using 24.5 grns of Longshot, Federal Hull, Z16 wad & Win 209 primer.

I'd like to use this load to temps down to about zero.

So....my question is how will the cold effect this load in your opinion?

I'm all ears!

Thanks and I hope everyone has a great Holiday Weekend!

Greg

Not trying to be a wise guy, BUT

You know what opinions are worth Embarassed

Put the loads in your freezer for 6 hours
Retrieve them
Step outside, load the gun, shoot at the clouds and you will KNOW!

If you have to go to a range, use an ice chest with blue ice and repeat above and you will KNOW.

Please report back

Mike

Or, since you are in North Dakota, about next January let some loads sit outside overnight, then see how they perform. Smile

The freezer is an okay idea, but not nearly as cold as when Greg wants to use these loads. I would contact Hodgdon - they know more about this stuff than we do.

I wouldn't worry about that load. I don't believe it will test out at that low a pressure.

Jeff , (JNW )

I thought Greg wanted to test at about Zero

What temp is your freezer?
Mine is set at minus 3 degrees.

Do your shells really get to as low a temperature as zero F? Where do you keep them when you hunt? Is it waterfowling, where they can cold-soak on the ground? Even in a blind, your body will keep the shells a lot warmer than that. Is it upland hunting? Your pockets, even in your vest or whatever is your top layer, will be a lot warmer than the ambient. In either case, upland or waterfowl, put them in the pocket of a more inside layer of clothing. They won't get colder than about 50 or 60 degrees. Total non issue. I'm originally from ND, and still hunt there.

where dis tis data come from I use a lot of Long Shot and that weight with that charge of powder should be about 9000 psi in a 16 ga. the 1oz loads with LongShot is where the pressure is low and the velocities are higher.

Mike,
I don't have a freezer with a fancy digital readout. I will admit to not knowing that freezers were that cold.
I have had hunting ammo sitting in my truck that got to ambient temperature. While target shooting in winter I have seen people have trouble with loads that were left in their car. When shooting sporting certainly seen loads kept in pockets start to get pooky an hour into it when the temperature is below 20 degrees. My Promo loads turn to crap below 40 degrees and I have to shoot that powder up while its warm.
We could start discussing the effects of cold air on patterns. The air is much denser in winter, causing more air resistance and making patterns open up. At over 35 yards pattern open up by at least one degree of choke.
Regards,
Jeff

Hi all, thanks for all the great replies much appreciated. The load would be used for upland birds of course. My boys and I aren't fair weather hunters, we hunt whenever we can, below zero or above. The shells would be kept in the ammo pouches in my vest (a Wing Works BTW) and those pouches do get cold. As to how warm those pouches get, I don't know, but 50 to 60 seems pretty warm to me, but who knows.

As to the load, it comes straight out of Lymans 5th, page 181.

Anyway, I've got some "cooling" right now and I'll give Mikes suggestion a try in the AM.

Thanks again all!

Greg

That load must have been tested on an off day. If you look at the one oz loads you will see that 24 grains produces 7400 psi. I had that load circled and did not put it on the spreadsheets as it did not look right to me. Maybe a misprint.None of Hodgdons loads come close to that one.

Hey OH, I see what you mean, but in looking at the 1oz load you mentioned, I noticed that the wad is different (a SG16 not a Z16) and the primer is also different (a Fed 209A not a Win 209).

The load I mentioned is also listed on the Yahoo Spreadsheet on the wad section.

So.........the 1 1/8oz load I posted could be right. Heavier payload, and different components.


Anyone else have any thoughts on this?

Thanks again!

Greg
