pellet weight advise

[ledders666 6]

hello

 

I have recently bought a AA S200, .177. Would anyone be able to sum up the effects different weight pellets will have on the gun, its mostly used between 25-40 yrd's for targets and rabbits.

 

Thank you

A lighter weight pellet will reduce the Muzzle Energy, so if you set the gun at 11.5ft/lbs with a light pellet and the police tested it with a heavier pellet you would be done for possession of an illegal firearm as a heavier pellet would likely take it above the 12ft/lbs legal limit. Unless of course you had it on your FAC.

 

A medium weight pellet is Ideal for the S200's Air Arms Fields, Crosman Premier aka Accupel etc....

 

but when setting the power of the gun use something readily obtainable such as a Bisley Magnum heavy pellet and set the gun at 11.5 ft/lbs with that, then you know your unlikely ever to exceed the legal limit.

 

As for the practicalities a heavier pellet will have a more pronounced trajectory.

phanroms right as a rule of thumb but every now and then you'll find an exseption. the only way to be sure is with a chrono and a set of pouder/jewler scales and a bit of home work.

 

varience within a tin widen your grouping, as does varience in gun power shot to shot, its not that much with desent pellets buts limiting to 25-30 yards with a bad pellet brand or bad pellet/barrel match.

 

you'll never know for sure without the chrono and scales tbh.

Just try a few different pellets and pick the one type that gives you the tightest grouping. If you have bought the rifle from someone else, ask them what they were using, they may have done much of the experimentation for you. If it is brand new, try known pellet types from other s200 owners that work well in their rifles - THIS IS ONLY A STARTING POINT. You still need to find a pellet that works well in your barrel - that includes the head size of that pellet, .177 pellets come in three different szes! Different barrels prefer different head sizes. BSA tend to like bigger ones.

.177 4.51mm

.177 4.52mm

.177 4.53mm

 

Although they are all .177 and they will all go down the barrel happily, they won't all give good accuracy through your barrel.

 

For a good all round pellet use round headed (domed) style pellets of medium weight (around the 8gn-9gn mark). Give pointed pellets a wide berth. They will not hold their stability at range.

thanks for that, at the moments im using AA diabalo field, 4.5mm 8.4 grains. These seem to be given good groupings, 10mm at my 32 yrd zero. I would say 90% of them any way, the rest are within a 20mm grouping. I may try some other brands if not go back to these they seem good.

i used those a while ago, slightly more accurate than daystates equivelent.

 

on a 2p edge at 50M lolol..seriousl! or was it a penny, i forget now but hey ho.
