![]() ![]() Will be interesting to see what can be done with 308 cast loads. Worst case if something doesn't expand at least with a 44 or 45 etc you get some sort of hole in the animal. ![]() On the other hand pistol style bullets get much better reports which would make sense as its an industry designed around low velocities that sorted out subsonic expansion decades ago. Unreliable expansion in the long bullet types for the 308 cal or difficult to get the more specialised bullets. Similar conclusion I came to after looking into subsonics. wanneroo Warrant Officer C1Ĥ50 Bushmaster is probably a better bet. If they are using 300 BLK it's supersonic ammo often with suppressors.Ĥ50 Bushmaster is probably a better bet. Subsonic 308 would render about the same results. Not enough energy for that to take down a pig/hog. We have quite the pig infestation down south in the USA and I've not heard of people using subsonic 300 BLK on pigs. and it’s just not fair to the game we pursue so just grabbing a 220 grain Sierra round nose is bugger all improvement over a Fmj. the point I’m trying to make is that at subsonic velocities bullet performance is extremely dependent on the softness of the lead and the design of the projectile. and a much softer lead marble also thrown by hand will probably show a flat spot on one side. you might get a tiny flat spot on one side of it. Now image a hard cast lead marble that is thrown by hand at the same wall. Of course it’s going to expand or fragment. imagine a marble sized lead ball hitting a brick wall at 3000 FPS. I have bought a 450 bushmaster and intend useing hollow point 300 grain xtp s that are designed to expand at pistol velocity.the new rifle / ammo choice also gives me 35 per cent more energy to do the job than what the 300 blk subs were giving me. No matter how you slice it powder shift is definitely a thing. The case capacity of the 308 would make it possible, but a lot more difficult to have consistent subsonic rounds. I have no doubt that with fast 125 grainers the 300 blk can perform nicely on pigs. You have about 150 more choices of powders with a Blackout. but this ammo is a wounding combination on pigs and should be outlawed one this size game. he was not phased at all on the last hunt when I used 300 blk subs. One American company quoted me 7500 dollars to send me 200 copper expanding projectiles I wanted to go down this route because I was trying not to deafen my sniffer dog.I shoot close to him and he just about has a mental breakdown next to my 243. all the copper stuff that is also soposed to work is impossible to get a hold of Australia or otherwise.
