Actual difference to hit rates from heavier carts

[Mr_Logic]

Right quick one folks (although I suspect it's a can of worms)...

 

Looking at shooting either my O/U or semi auto, and in the semi you get a heavier cart with more lead in the air with the same (or similar anyway) level of recoil.

 

Assuming that both guns fit the same, is there a real difference on the clays from putting more lead in the air? There's a theoretical difference sure, but am I going to see this on a round of skeet or an afternoon on the sporting clays?

[Chard]

You can't use more than 28g anyway.

 

Don't think there's much difference on close in stuff like skeet anyway.

 

I believe it could make a bit of difference on rangey stuff though

[utectok]

No diff I think up to 35yds some say the lower recoil makes them score higher with the light loads. Might get a few more 40yd plus ones though?

[Mr_Logic]

Hmm... I normally shoot 21g carts with an o/u, but got the Beretta and it's not liking them at all, hence thinking of shooting 28g for both. Other half likely to have Beretta but I might get another one...

With my limited ability (typically 50% of the targets in Sporting) I've tried 28gr and 24gr and the heavier loads makes no difference at all - so now I buy 24gr. I seem to remember reading somewhere that a 28gr 7.5 cart has about 30 more pellets in it than a 24gr of the same type....I guess if I'm on target then those extra 30 pellets don't make any difference and if I'm not - well I've missed anyway!

When loads went down from 32gm to 28gm some years ago,scores didn't go down.The Olympic disciplines are shot with 24gm loads and their scores haven't suffered.I know several people who shoot 24gm loads,some in competition and they are happy with their decision. The 21gm loads are,surprisingly very good also.

The science bit is to do with the shorter column of shot in the cartridge suffering less from compression during its transition down the barrel.Hence there are fewer distorted pellets and therefore fewer fliers and better patterns. How far you can go before the lack of pellets really makes a difference I've no idea.

had a chat with a veteran at the club he wins more than he loses, he uses 7/8 then full choke. (you need it open a little)

28g cartridges 7.5 and 8,

 

i expect he could perform the same with 1/4 oz !

 

what about the .410 guys. they hit more than some 12gauge guys.

 

choke and skill ! is all it takes.

[Mr_Logic]

Ok. So all that being the case, why do folks still use the 28gr stuff?

Maybe because it's the 'norm' and we haven't tested anything else yet, creatures of habit and all that. I tried a box of 24grm last month and thought they did just as well as 28grm, until i said "these 24grms seem to job the job perfectly", then missed the next pair. I still buy 28grm.

[VicW]

28gm is the standard competition load in this country,it is available in the greatest variety of prices and types and the fact that the usual belief is that the more lead you have the better will be your results.

Try lighter loads and I mean more than one box,you may be surprised. Incidentally,although I have tried 24 and 21gm loads with some success,I am still using 28gm because I bought several thousand before the last price rise.

Thanks folks. I've been shooting 21gr Comp-x on the skeet for a while with success, only the arrival of my Beretta AL391 changes things as it won't cycle them.

 

Other question - having sold the other half's 20 bore, I swapped some 20s for a slab of 12, and being as 20 is expensive ended up with some Pro Ones, (28/9). Now they are much more expensive so I wouldn't normally get them. Yes, they did seem to work, as I shot a 21 with the Beretta which fits the other half much better than me.

 

However, I don't believe a cheaper cartridge would make much difference. Coming from a rifle background, a rifle bullet gives better groups when the copper is good quality, and the consistency from round to round is high (as a general rule - some rifles obviously just hate some loads). In the shotgun world, surely it's just a question of it goes bang and some **** comes out the end of the barrel.... or is it?! (clearly the answer is the latter, but please enlighten me as to why!)

...... I seem to remember reading somewhere that a 28gr 7.5 cart has about 30 more pellets in it than a 24gr of the same type....

 

The Hull Cartridge website is good for finding this sort of information. According to this page the 28gr has 378 pellets vs 324 for 24gr. :o

It's odd the way some 391's will cycle 21gm and not others,mine cycles them OK. It is possible to change the spring in the gas regulating valve for a stronger one that vents less gas and supplies more to the cycling action.

I'm sure one of the experts will be along in a minute, however I believe that theory is that the better quality carts use lead shot that is coated with a material to make them harder and thus less likely to deform as they head down the barrel. Once clear of the muzzle the pieces of shot that are still sepherical are aerodynamically advantaged whilst those that have been deformed are likely to be rather more wayward - becoming 'fliers' and too far off the target line to be any use (unless it was me that pulled the trigger of course :o ) .
