I have also done quite a bit of experimenting with hunting and varmint bullets. Some of my favorite varmint bullets are nosler ballistic tip, vmax, amax, sierra blitzking and use softpoint 55 grain hornadys. I put up lots of fur so I do like a bullet that does minimal damage.
Some of my favorite big game bullets are the accubond, partition, and gameking.
I have found a severe dislike for TSX, Berger, and Ballistic tips. The TSX is not much better than a full metal jacket unless you run into bone. The Berger and the Ballistic tip are grenades if you shoot animals at close range. That being said a sierra game king is right on the edge too.
We have similar experience. I shot a pretty nice buck in November in kind of a fluke situation. I finished chores with maybe five minutes of shooting light left and just grabbed on of my .260's and took about a 200yds walk through the heavy mesquites to the edge of my CRP field which borders my neighbors wheat field. That time of day it's real easy to catch coyotes slipping along just on my side of the fence and I wanted to try punching one.
I was shooting 120gr SGK's which I'd always considered a respectable hunting bullet but after seeing the wreckage in that buck I really wanted to throw up. We lost at least ten pounds of meat because the bullet shelled out more like what I'm used to from the NBT's. I'd had some do that in the STW on shots between 300-500 a few years back which turned me away from them and the whole Sierra line with the exception of shooting their 55gr bullets at varmints and predators in my .220 Swift.
Because of my granddad's experiences growing up through the depression there's one golden rule about wasting or ruining food, you simply don't do it. That was heavily reinforced when I was in college because Jimmy and I lived almost exclusively on wild game and fish that we caught.
I have yet to ever, even once have a Hornady Interbond, or Nosler Accubond fail to perform as advertised and expected through literally hundreds of game animals taken with them, I just find the expansion of the Peregrines to be even much more to my liking. I've also had good luck with the ABLR and Hornady ELD-X for the most part but I've also had some ELD-X's come break up on me just like the interlocks did frequently with High impact velocities of 2,500fps or more. They haven't quite lived up to their billing terminally but they do shoot well.
As soon as it dries up enough to get to the range I've got a bunch of ELD-X's loaded up for the .300 Rum, .260 Rem's and 7mm STW with various powders and charges to try and narrow down where I reach the highest accuracy potential with them so I'll be checking in on the Alliant Powder and ELD-X threads after that trip to the range.
I have I think 200ea for 6.5, 7mm, and .30 cal and about the same numbers of ABLR's for each of them so when/if I get to that OMG load for each of them I'll use them in the off season for plinking, varmint, and predator control. My neighbors are calving right now and they really like me to patrol their calving traps as often as I can night and day to try and keep the coyotes and pigs thinned down as much as possible and of course I'm glad to oblige.
I pulled the rest of the SGK's and threw them in the trash.
As for the ttsx I actually found it to work very well in the AR's on slaughtering pigs and coyotes. Those are strictly depredation loss prevention kind of hunts where the only thing that matters is putting a hole through them and preferably doing so in such a way that if they are in a tilled field they'll run out of it before they die. Farmers really tend to hate getting a dead hog or coyote jammed up in a disc or wheat drill and quite frankly I don't blame them. Since my lifestyle has resulted in just about all of the cartilage now being dead and gone in my right ankle I hate walking across a hard clay field or pasture full of cow tracks just to drag one off where it won't get inconvenience the farmers any.
I ran into them on the road just coming off of the highway day before yesterday and I told them where I'd been the coyotes I'd shot and warned them that the pigs were starting to show in and around their calving pastures and you couldn't see two happier guys or more appreciable people. They thanked me up and down the wall for "looking out for them" and I just laughed and told them I'm glad to help but more than anything I was having a ball.
They are the kind of neighbors that define the term "Neighborly People" to a T.
