.410 Payloads

Post by SwampDrummin »

Starting to think about the .410 build. What are the largest payloads y’all .410 users use andwhats the lArgest payload y’all see in some of tthe .410 recipes?

Hal's (Hawglips) loads of 13/16 oz. or 370NM. The 13/16 oz. translates to 355 grains of shot while the other, 370 grains. One .410 shooter I know prefers the lighter load to the heavier as it shoots a little wider killing pattern at 40 than the heavier in his gun. If you buy the shot from him, he will provide recipe.

370 grains is the biggest payload in any of the recipes. This equates to 27/32 of an ounce.

However, I prefer the 13/16 ounce payload because of the addition of mylar. Just like it in the recipe because of the extra barrel protection.

Also with straight 9s, my 870 .410 bore averages 145 in the 10 and about 270 in the 20 with the 13/16 ounce load. I have been more than pleased with that load. See no reason to change. Trigger time will tell what each particular gun likes. This gun shoots 9s much better than 10s, even with the increase in pellet count that the 10s had.

I am shooting the 13/16 load with 9.5, TSS. My plans are to test the #10 shot, for next season. If you haven't tried the 28 gauge, I would sure give it a shot. I think it is a little more " user friendly" than the 410. JMO

Someone reported success using 13/16 oz. in the 370NM load because of increased velocity and reduced pressures. In order to shoot the 13/16 oz load at reduced pressure within SAAMI guidelines, a lower charge of powder was recommended by Hal. This decreased velocity below the speed of sound. The pattern deteriorated more rapidly beyond 40 than higher velocity loads according to some reports. The reduced powder load was definitely subsonic as there was no "crack" accompanying the "boom" and impact of shot could be heard against the target at ranges over 30 yards. "Boom-whack". Gil

There's only so much you can put in the appropriate wad.

You can do 7/8oz out of a 5# 20 gauge. .410 and 28ga seems to me to be more about the size of the guns than the shells in them.

I done this very thing. I actually consulted Hal and seen what he thought about this before I done this. He said it would be ok.

I loaded the 13/16 ounce payload over the 370nm powder charge for increased velocity and used a nitro card to stop powder migration. The load worked great. Only downside is you have to use a BPI crimp bit as there is not alot of hull left above the wad for crimping. But, the BPI bit worked well, and there was not a flake of powder migration all season for me from the loose fitting TPS wad. It done very well. It will be my go to load in the .410 bore. No questions asked.

Any idea of the velocity?

Honestly, I do not. I really need to have them tested, but I haven't done it yet.

pressure won't be the issue with downsizing the payload. Maybe one of us can chronograph it. I don't have one, but a friend may.

I agree, even with the addition of the nitro card, I don't think pressure would even be close to max. It's a hard hitting little load for the .410. I would be curious how fast it is going.

Hey VALongbeard, have you shot that load at 50 Yards? If so what did it do? Steve

Has anyone seen any choke damage running the 370nm load with #9 shot?

I don't see anything in the bore that I can tell but my choke tube is pretty skinned up.

I an not sure it was there with the 13/16 load.

Steve, I have not. 40 yards only. Averaged 145 in the 10 inch and 270 in the 20 inch with straight 9s.

VALongbeard, did you use the same powder charge provided in the 370NM recipe or did you reduce it?
