London Best Posted July 20, 2022 Report Share Posted July 20, 2022 When I wanted to try the 9’s in .410 I had to order them. I tried one slab and was impressed enough to order another. They are not my usual load as they put too much lead in game and I like to eat game, but they absolutely cut crows to shreds. Obviously, I never used any on rabbits. Somebody has already posted that the largest sensible shot for a .410 is English size 7. This has been my (long) experience and is the biggest I ever buy. Works fine on rabbits but really puts too many pellets in them for eating purposes. If I was using my .410 for ferreting I would go up another size, but over 99% of my rabbits are rifled. Nearly everyone keeps talking about loads of 19 to 21 gram in a .410. You all forget that is a .410 MAGNUM. A .410 shoots a half ounce (14 gram) load.

Ultrastu Posted July 20, 2022 Author Report Share Posted July 20, 2022 I believe stone Park is right with his hollow cone theory of the shot column . This especially holds true foe the smaller calibers . The least damaged pellets (on exiting the bore ) will be at the middle and front of the colum as they will hold the most speed and energy and arrive on target first . The ones at he back and round the out sides will get more damage and hence lose speed faster (lower bc ) these will arrive last to the target and generally make up the pellets that hit around the point of aim making up the width of the pattern .

I am sure this is not our friend Stonepark’s own theory, as I am sure he would be the first to admit. The shot column being like a funnel travelling neck first has been an acknowledged fact for at least a hundred years. Quote Link to comment Share on other sites More sharing options...

Both Bornaghi and Fiocchi do, do them but not imported here due to normal bias that you need 6's https://www.bornaghi.it/en/natural/magnum-19/ https://fiocchi.com/en/870804-870810.html Nice! Simply out of interest and assuming 21g is c429 pellets, as my old eyes can't be certain, is that 30" outer, 20" inner with 92 and 146 pellets respectively giving 238 in the 30"?

The figures equate to a 1/8th choke but the pattern itself as you say gives a light modified performance. I've started having a look at the .410 with c16g of 7&1/2s in mind. For medical reasons I was looking at OUs but the cheap and cheerful variety all weigh more than my 20 bore which defeats the objective. 14 minutes ago, Stonepark said: Correct, but we now have high speed photography which helps confirm the "theory". Unfortunately, this compounds the issue. Previously if you missed or wounded a quarry it was because - well - you missed. Now you may well have centred it in the pattern but got the same result, but just too far back where the pellets are as sparse as those on the edge of the pattern.

I reload almost all of my 410s and have gone to 6s in bismuth because that was what was vailable. Up[ to me to pit it in the pattern.. For clays, yes no problem, shot thousands at skeet . I might be happy to use 9s in my 410 for walked up snipe. Now that would be fun. Quote Link to comment Share on other sites More sharing options...

You wouldn’t happen to have any Bismuth recipes using fibrewads per chance ,I have all but given up hope of finding steel wads in this country. I have Bismuth ,new hulls ,powder including Steel csbo bluedot ,I know I can get fibre wads just need some tried and trusted recipes.

I spoke to Folkestone engineering and they said just use the same load you would for lead just swap the shot to Bismuth Quote Link to comment Share on other sites More sharing options...

I changed pwoder from SP3 to LilGun because that was what was available and dropped the powder load to 0.9grams under 18 grams. Quote Link to comment Share on other sites More sharing options...

Life is never easy! I substituted 'load' with 'charge and read the rest as 18 grams over the now reduced 0.9 grams (13.89gr) and it seemed to make sense.

I see now exactly what terminology you were using. My mistake. I have never known a powder charge to be measured in grams, just grains. I read it that you had lowered (dropped) the powder weight to less than 18 grams and I thought you meant to write shot load. Quote Link to comment Share on other sites More sharing options...
Gas seal Posted July 21, 2022 Report Share Posted July 21, 2022 Hi Holloway I have.410 loading data with csbo powder but it’s with plastic gualandi micro h17 wads and 19.5 grams of lead. I have loaded 28 gauge with csbo power and bismuth. The data was for lead shot. I just used the same weight in bismuth . Quote Link to comment Share on other sites More sharing options...
