I use the 150 gr ttsx in my .308. It is loaded with 44 grains of IMR 4895. I cannot give you any velocity or ballistic particulars on the load, but it is a very accurate load in my rifle. I have used the 150 grain ttsx bullets in my 308 on whitetail, hogs, elk, red stag, wildebeest, gemsbok, leopard, waterbuck, zebra, bushbuck, and impala. Red stag and wildebeest being the only animals that were given a follow up shot.
Alaska, sorry I can’t help you with the 308, but I’ve had pretty good luck using the online accuracy loads on the Barnes website. You might try them. They have worked pretty well in my 30-06, 300 WM and 375 H&H.
Best of luck!
Hello Milan, I just watched your video on disassembling/reassembling the CZ 550. I have spent days looking for something like this. I now have no reservations taking apart my rifle. I like to do this with all my guns so I understand them "inside and out". Thank you very much for the information. It is greatly appreciated.
