fastest 410bore powder?

[cpileri]

Learned Sirs and Ma'ams,
What is the fastest burning/most reliable/stable burning 410bore powder you have pressure tested data for in 3" case w 11/16oz (300gr) load?

I am still working on my 410 pet load, but w296 is not doingnit for me- too low pressure and in my particular case i cant load any heavier shot weight, no stable burn.

i haave only a few loa dmanuals, and the fastest w 11/16oz is HS-6.

Any recommendations appreciated!

I wasn't impressed with 296 either. Could only get about 850 FPS in the 3 in. 11/16 load. Powder in hard to find here. I been using Accurate #9. Very little data out there but it works for me. If you look at a burn chart #9 is very close to 2400. If I could find some 2400 I'd try it. I been shooting 3/4 oz/327 gr. of 5's on squirrel this year. Been having a good time with the Stevens model 67 I picked up. Hope other people join in on this. I'm new to loading the 410 also.

4227 and h-110 i hear are good in the 410. i know 4227 at 10gr in 2 1/2" wooks nicely at droppin squirrel with 7 1/2 shot

Thanks Guys (or Gals, if you are).
Where does 300MP fit in the burn rate chart?
The chart i am looking at, from Handloader issue 275 shows 410 powders like this:
Fastest:
Sr-4756> HS-6> Blue Dot> Longshot> Alliant 410> 2400> Steel> Lil'Gun> H110>w296> 4227's

with the ones from Lil'Gun onward right on top of one another. 300MP isnt on my chart.

Unfortunately, i dont have any 4756.

Have you considered the 1/2 once loads for the 3 inch shell?

Very new to reloading the 410 and I've found, at least on the trap field, the 1100 FPS of the 3 inch 11/16 oz load a little slow for leads and such.


Looking through my old Lyman number 2 shotshell book I find a bunch of 1/2 oz 3 inch loads running from 1200 to 1500 FPS.

Not sure I want a 1500 FPS load, might have pattern "holes" but sure wouldn't mind bumping velocity a little to reduce lead on target.

on the hunt right now for a loader and some 4198 which was the go to powder for all the 3 inch loads listed in the Lyman book, then I'll do some patterning and see whats up.

BY the way just picked up a new ATI cavalry 410 O/U with screw in chokes, what a dream! currently running full and improved Mod. in the barrels but that may change as I develop a load for this puppy!

[cpileri]

what i really wish was someone had developed a pressure tested load in 410 w Unique!

Thx for the reply. the 2.5" hulls dont hold the number of buckshot balls i am working on.

i know i didnt say what i was up to, though it is in an old thread here, but its a specialized 410 buckshot load. So right now its 3" hulsl only, and the payload weight (300gr or 11/16oz) is not changeable for now.

This is all in development of ocurse, so I may have to scrap the above restrictions. but for now, i just need a stable and reliable ignition and burn beyond what w296/h110 can do.

Maybe black powder?

[cpileri]

looks like its the same as h110. A bit too slow for what (I think) I am after.

Lil Gun would be better suited for your needs.

[kenyerian]

little Gun works best for me.

[cpileri]

what large straight rifle case has s similar internal volume as a 410 3"? when loaded similarly, i.e. shot down into the hull gives saller effective combustion volume? 444 marlin maybe?

If i can find a 444 marlin or similar cartridge w a 300gr bullet using Unique annd is under 12Kpsi, maybe i have something to experiment with...

p.s. if you get too fast the lead balls will compress, deform and form a blocking
barrier in the leade and barrel, be VERY careful as pressures will skyrocket

Fun reading and 1600 fps, WOW
