6 and a halfs


Recommended Posts

when rough shooting i use a number 6 usualy in 30grm loads sum brands are better than orthers but as long as its a 6 then im happy that what ever i flush on the day be it mallard/phseasnt etc etc then i have a cartridge that will do the job, well i can now get number 6 and a halfs for £1 a box cheaper than the number 6s im currently useing so would there b a big difference in the killing power of a 6 and a half compared to a number 6, although before id buy a batch of them i will try a box to see what they are like does anyone use 6 and a halfs

I've used 6.5 Hull Fitasc 28grms & a half choke for years in the fields to shoot everything I lift the gun at although I find them a bit strong for woodcock,I usually use 7.5 28grms.

 

I bought a box of Express Super Game 36grm #6 last week to run through my Sportin Clays auto as it was jamin the odd time after I shot 21grms through it ~ I paid £7.50 for this box of 25 shells -- is that expensive for that sort of stuff ? I don't mormally shoot it so I don't know :good:

Have been using these since I first tripped over some Rottweil in the late 70s. Ken Chard once bit my head off for calling them 61/2 shot - quite right too, there's no such thing, they're 2.5mm. You don't lose too much energy and for a 1oz load you get the same number of pellets as you'd get for 11/8oz of No 6. NB the figures are nominal.

Still, as ever, you pays your money and takes your choice.

MB where are you getting the 6 1/2's and what price? I would like them for the pheasants. I use nothing but 28g 7 1/2's for woodcock.

 

ollie havent tried them yet but a mate was in lavin guns and he said he got them at £4.55 a box from there think he said they where winnchester brand, so a £1 a box cheaper than the 6s im currently buying so a we trip to lavin is due shortly

Have a shufty at this table = http://www.njskeet.com/files/shotgun_statistics.pdf -> look at the energy vs range - that's the "killing power" - e.g. at 25yards is twice the hitting power than at 50yards - (I know it has not got 6s but you cane get a very good idea of what's happening)- my sort of rule of thumb looks like -- 4 no.7 pellets at 40 yards in a bird is mortal - a session on a pattern plate using the same cartridges but different distances give you a good idea of your performance - i.e. the number of pellets in a square foot (or size of a 'target')

 

Of course - the diameter of the shot significantly affects just how far the pellet 'penetrates' the 'target' = mortal hitting power

 

Shot Size Guide>

 

Large shot hits harder, penetrates deeper, and retains velocity better than smaller shot. Small shot, on the other hand, gives denser patterns, creating more multiple hits on the target, since there are more of them in a given weight. Choosing a shot size is, therefore, a balancing act between sufficient energy and adequate density. Use the accompanying chart, tempered with your own experience and the conditions you encounter locally, as a guideline.

Purely on the grounds that the table mentions species that we don't shoot, I'm wondering if it is of American origin and if so, are the shot sizes also of that ilk.

That's a bit like me asking you - can you fire a single ball of a 1/12th of a pound of lead in a 12 gauge shotgun ? :blink:

 

I would like readers to "work through" the process of shot size selection for a specified target = the ORIGINAL poster question; which was 'limited' to 6s vs 6 1/2s :good:

 

Here is a UK based company's info ! = :rolleyes:http://www.hullcartridge.co.uk/products/game/three_crowns_hp.cfm

its no secret that i do prefer the bigger shot.

 

in a everyday sport cartridge of 1300fps, #5 cant be bad. its a great load, retains energy well.

 

my #4 subsonics, at 1000fps, still have greater energy than a 1300fps #6 at 40yards. thats why i prefer the bigger shotsize with a limited speed.

its just simple i took a data table and compared the speeds at p1 and p2 (muszzel and 40yards) it just so happened they patterned tight.

that was just a bonus.

 

there is nothing wrong with using a bigger shotsize.

 

i`ve heard guys use #6 for everything, including geese !

#5 shot isnt magnum, wont blow your barrels, or change time / space. its just different.

the bigger one, it should hold on to its speed for longer too.

the energy is the speed.

 

heavyer pellets loose energy less than smaller ones.

 

9s have a maximum range of 200yards, 6s 300yards and SGs a mile or so?

incidently, if you handloaded something called TSS. it is twice the density of lead, meaning if you were to shoot #9tss its about an equivalent to shooting 2s, same shotcount too. but the 9tss will actually retain more energy even at 90+ yards,

 

this has to do with the pellet size, weight, and its ballistic coefficient.

 

steel has a severely poor coefficient. thats why it has to be shot at 1600fps, just for 40yard shots. its to do with its low density.... of which is about 7g/cc where lead is 11g/cc and TSS is 18g/cc.

 

depleted uranium is 20g/cc !

different ranges have different rules.

 

but the consensus is maximum 7.5 and 1oz

 

some places allow 32g loads and #6 for zz shooting.

 

maximum range for #6 is about 300yards.

Have a look at "Energy Density", same sort of thing as "Sectional Density" in rifle shooting.

 

1500 divided by cube root N where N is the number of pellets/oz. The Modern Shotgun by Burrard, empirical in nature but pretty damned close for the most commonly used shot sizes.

If you are happy with 6.5s then use them, you will not notice much difference from the 6s you now use. Just be aware that they may despite what the box says have a different velocity to your normal cartridge, as a result they may want a bit of getting used to. Put the pattern in the right place and the bird will come down provided it is within effective range. Under 30 yards then anything from 4s to 7.5s will do a job, some a better job than others especially if you are eating the result. My last woodcock I shot with 36gr of 3s when waiting for wildfowl on a flight pond !!, totally unsuitable load but it did the job.
