I've been trying to work up a load for my Remington Sendero in 7 mag- I thought that I would be able to use a heavy enough bullet that would trick the wind and not expand creating less pelt damage.... haven't looked far enough! I shot a 40+ lb coyote today at 187 yds right behind the ribs (trying to avoid any bone whatsoever) and I got an exit hole that I could fit his head in. Bad call on my part. Guess I'll have to give the GameKing's a try. Already tried the 110 gr Speer TNT's and they had as bad a result as the 130's. Anyone else shooting a Seven with insight would be appreciated!

Sloan, I've still got a box of them left but I can't get them to shoot. Tried RL 22, IMR 4831, IMR 4064 (which puts the 130's in .8 @ 200), Retumbo, IMR 4350, etc. I've tried slow and fast and it ain't happening. Even tried three different kinds of brass and primers. Not happening? They recommend faster twists than I've got so I'm going with that as the problem since it shoots the 168 Sierra's without a problem. (By not shooting, I mean I can't get it to put 5 into anything less than 1.5" which isn't acceptable where 600+ yd shots are a possibility.)

What powder are you using?

I'd really like to try the Barnes Banded Solid in 140gr but Midway shows their next availability as 07/12?!
 
My go to bullet is Barnes TSX or TTSX in my 25-06, it hammers them and they dont blow big holes. I just started working on a load using the 160 TSX in my 7mm and I am positive it will yield similar results. Also Barnes are very easy to get to shoot very accuratley in pretty much anything.
 
Mike, 7mm Rem mag? I'd like to hear how the 160 TSX does for you, my experience hasn't been very good. Only what I can attribute to a translational & rotational velocity issue. I feel that the 7RM doesn't quite have the poop to launch the 160 TSX at adequate velocity to create the rotational velocity necessary to avoid upsetting angular momentum after hitting an animal. My hunting partner started with the 160 TSX (albeit factory loads) & we've seen some bullets do some pretty erratic stuff after hitting game. Basically, I'm saying that it might not be spinning fast enough to track straight through a big game animal, after entering an animal it seems as though the bullet starts to precess (wobble) & some of them end up in places they shouldn't be. These results were noticed quickly & we quit using the 160, he's using the 140MRX now with perfect results on deer sized game, we haven't gotten him on an elk yet. I do think the "big" seven's can spit'em out fast enough to take care of the issues (theoretical or otherwise:D) I have noticed. Who knows, maybe my partner just got some bunk ammo & i've been thinking WAY too long about it lol

To the OP: Sorry for hijacking on you, just started jabbering... the banded solid will work very well, but that lead time is ridiculous. Have you tried contacting Barnes directly? You can order straight from Barnes as well. If not, pick up the bullet weight & drop the velocity, that should provide you a dead 'yote without the claymore effect.

My 7RM Sendero got along great with the 150 TTSX.

I should have posted in my previous ramblings that, I too shoot the TTSX in my go-to hunting rifle. The TSX & TTSX have been VERY accurate in everything I have developed a load for, I was in no way knocking one of the truly premium hunting bullets. Just sharing my observations...gun)
 
I went and shot a quick group tonight with the 160 tsx and got a .5" group. My velocity was pretty low but its coming up. I am hoping to get close to 2900... we will see.
 
Thanks to all for the pointers. I'll be sure to try them next chance I get. Right now, I've put it on the back burner and am loading up for my Tikka 22-250..... a little more tried and true round for yotes. Just won't be sending any hail-mary's out there past 600, have to refine my close calling game a little more ;)
Any stink about the 50 gr Sierra BlitzKing's from anyone or the 40 gr. lead-less Nosler b-tip?
 
I have not tried either but I have never tried a sierra bullet that didnt shoot well. I load for 3 22-250's 2 are tikkas one is a savage and they all shoot extremely well with 52 grain berger target and 52 grain berger varmint. Depending on what your looking for the varmint bergers dont exit the target ones usually do. I prefer the Target bullets. I think the 50 Blitzking would be a pretty fine choice.

Good to know, although keep in mind, accuracy was never a problem for us either. My thoughts tend to tell me we were close to the edge (green side) for stabilization? That bullet is LONG, it was the on game performance I didn't like... I sure wish I would have chrono'd that, I tend to think that if a guy can get the velocity up a little further than the factory loads, which shouldn't be hard to do, the rotational velocity will be higher & the internal performance should be what Barnes are well known to do. That is track straight through & smash everything in it's path. I know is sounds like I'm trying to shy you away from them, but that isn't the case, I just want to relay what I have both seen & heard from that combo. I would personally like to see me proven wrong! lol Thanks for putting up with me.

OP, the Blitzking is one of my Favorite varmint bullets, I was pushing a 40 grain BK in my 22-243 at well over 4600fps for a while, that will put a smile on your face! Very accurate bullets as Sierra's tend to be, I don't anticipate you being disappointed.

I am really not sure what you mean by rotational velocity, if its stabilized its stabilized. I have heard about people saying they have had these bullets bounce around in an animal but have never experienced it. I guess I will find out next hunting season because I plan to use it on at least a few things.

To the OP sorry for hijacking the thread, were back to your subject now. I sent you a PM about doing some coyote hunting.

Ditto, Sorry to divert from the point of origin.

Mike, PM'd ya on that.
 
162amax 4350 work up.Calibur size hole in an out at most anyrange. I don't think we have rotational what ever up here,be safe shoot center mass an don"T quit.SLOANgun)
