Thread: Subsonic 308

As promised tested out the 90 gr xtp pistol pills today on a couple of small pigs in a sty.
Unfortunatly the rifle i developed the load in was out on loan so used a full length suppressed Tikka i had in the safe.
So can't say exactly the velocity but i went up .1 of a grain for longer barrel and it was still quiter than a springer air rifle.
Im picking 900-1000fps.
First one was down threw head as it ate a pie and of course it dropped on the spot. Totally smashed top of brain box and exited threw jaw . Found a small shard of copper under skin of exit.
Second one wasn't very cooperative after watching his mate but eventualy got broad side shot on it threw the hillar zone.

Lept 2 steps and fell on its side with a garden hose of blood spurting out the exit. Maybe 5 6 seconds till just nerves.
Exit



Heart and lungs left blood from chest cavity right.



Took out the major blood vessels above heart and one lung. More than cal damage here.

Entry



Exit





I think i can safely say it expanded however this was at ten feet.
Further out could show issues but can't be tested till tested.

You gotta be kidding right? 70-80 odd yards would have to be a realistic max range with subsonic ammo, Rainbow trajectory and bugger all energy means you are basically shooting a bow but with another 40-50y effective range.(and you would have to range to be sure of your drop and proper placement)

I will try them on some goats at some stage a bit further out, I dont like wounding things so pigs in the sty was a good controlled situation to se if the expand up close and will work out from there.

That was 5.9gr trail boss fed brass pmc lr primer.

hmmm, i guess 200 would be pushing it

holy crap ! if I typed in the correct numbers, you are only getting 161.8 ft/lb at point blank range... at 200m it would be below 100

you using the hollow point 309 XTP, BC = 0.115 (flying brick) ?

xtp's were the heads I used for carry loads on the 40S&W

I've just got 700 of these, I'm not 100% sure exactly what they are but I've been told they are for a 30 M1 Carbine , 110gn hollow points .
I'm going to try them in my 308 with trail boss .I will load them up though because there is no real reason to go sub sonic here because of the no moderators law .
Anyone have an idea of how fast trailboss will push 110gn bullets ,all the info I can find is related to 150gn




Ken

Yea the 30 cal pistol pill. Dunno the bc, kinda irrelevant at the speed launched and intended effective range.
Be interestin to see how fast could get them goin but i don't have any powder fast enough for that.

Heavyer would be better to gain some energy.(cos speed is fixed) but they still have to expand at low velocity or your just goin to poke a hole threw with no real damage.
Can't wait to try some of spanners when he gets production up and running

what about using lite-ish solids ?

110gr 30cal barnes, or is that a dumb idea ?

I thought the idea was to use big long projectiles ie 220s that cause damage by tumbling through the animal

If you can't get expansion and or fragmentation then that would be the next best thing.
How do you guarantee it tumbling tho and not just upsetting a bit and pissing off in a different direction in the animal.

Probably dumb answer but what if you took out all the rifling? I know you wouldn't do that to your .308 but a old .303 or something with a fucked barrel.
