sabots for a .308

i misread your post, sorry about that ..its what happens with 2 kids screaming at each other and me…i miss shooting daily

anyhow i would stick with lead….the plastic sabot will leave plastic crap in barrel, YN gave me a bunch of them to try where a 76 or 110 grain would work just fine, the sabot was all over the place, and i never got the energy out of it that i wanted…so i would say 10 bucks wasted

where in CA are you ? (probably best to PM that info)

been there done that

1 inaccurate (i dont think they get enough speed to properly separate)
2 the bullets dont fly fast enough to expand in the prey
3 too light in most cases
4 plastic shreds left in barrel

your much better off with some soft lead bullets between 75 and 120 grain…the heavier ones can be trilled out to make a hollowpoint do that thin-walled enough and pre-stress the wall by scoring them with a knife, and they will peel open like a banana

the heavier the bullet the more power your rifle will make (unless the shape of it leads to more friction in the barrel)

the beauty of 308 in a airgun is the low BC most bullets offer, the heavy weight means the bullet will carry its speed and energy so much further

i did the math some time ago and kind find it…so these figures here is just for illustration purposes

say you launch a .177 10 grain…at the muzzle you got 20 fpe, at 50 yards you may be down to 12 fpe

in .308 120 grain…muzzle 220 fpe…50 yards 210 fpe…only 10 fpe lost

now the math .177 12/20=.6 1-.6=40% lost energy at 50y
.308 210/220=.95 1-.95=5% energy lost and the fact is the 308 will probably be over 150 fpe at 200 yards !

these are example numbers…only to illustrate why .308 is cool

BUT .308 has a problem, the surface of the bullets makes the heavy ones long, and usually introduce a lot of friction in the barrel….other thing, the surface which the air can push on the bullet is small, remember that pressure is PSI “per square inch”…say your tank had a ultra tiny hole in it…you could probably hold the 3000 psi back with your finger or a piece of gum. now if you make that hole .50” and your hand will be blown into orbit !

the bigger the bore the more surface the air has to push on, the bigger cal. better killing power…and thats what it comes down to, we all know if you want to punch paper at 50y a .22 will do the job better than .50, at our speed and power limits

so instead of .308, i would suggest .45 (or .457 there abouts) theres ton of ammo out there in that cal, it will fit the talon frame…you can get about 400-600 fpe on a 3200 psi fill and a good 5 shots…..my gun got 15 shots from 1150 down to 900 with roundballs (140 gr) somewhere in the 300+ fpe….plenty for most medium sized prey….but for the tougher critters (hog) stuff a 400-500 grain slug in there an whammo with no change to the gun i got between 450-600 fpe…not too shabby imho, a .357mag makes about 500-600 fpe, 44mag makes about 700 fpe with cheap ammo, 45acp out of a 1911 will make about 450-500 fpe…yeah now we are rocking

at 450 fpe you can push a 400 grain through a metal pc cabinet, and though the power supply as well…4×4 planks no problem…noise yeah its loud hearing damaging loud !

i would say go with a 50 cal…but in a talon frame it gets difficult to fit a heavy enough hammer, and spring

with .308 i had bullet get stuck, and the pressure had to go somewhere, and so a few times it simply blew the barrel out of the gun…and launch it 20 feet, with .45 i never had that kind of problems ! its easier to find a .457 bullet at a gun store that will be the perfect fit for your rifle, than it is to find a .308 bullet

does any of this make sense….go .457 and you wont regret it…for many shots use light ammo, for high power use heavy
