25 wssm coyote load ? ?

hey guys, I have an Olympic Arms 25 WSSM upper for my AR-15 and was wanting to see if anybody has any good coyote loads for the 85 gr Nosler BT that work good with this upper. If you have any other good coyote loads that works good with this upper, I would be willing to try them too, but I picked up a couple boxes of these and would like to shoot some preditors with them. It looks like a good bullet for this format. I bet this 25 WSSM will really knock'em down......
 
Never shot a 25 WSSM AR but my A-bolt likes almost everything right around max. The only powder it doesn't like higher charges of is RL-17. The load I used for that bullet was a max charge of Varget for the best accuracy. What barrel length and twist is it?
 
I also have a 25wssm that likes 85gr BT with like 1/2 gr short of max of Varget. Mine is a Winchester Coyote but might not hurt to try some Varget. The extreme trauma caused me to limit this combo for non fur saving situations.
 
I read an article about the 25 wssm when it first came out, the author experienced severe bullet failure on close range coyotes using 85gr Nosler BST prototype loads.

I don't know if anyone else has had the same problem.
 
My 25 wssm does not seem to like 85gr BTs. Tried several different loads and just coudn't get them to group well. Mine has a Shilen barrel, so you might have a completely different result.

On the other hand, I got great results with 90gr Sierra Game Kings and slightly less than a max load of Varget. Had 1/2" 5 shot groups and a 3 shot group that measured .133". This should make for a perfect coyote load.
 
Well, I can't seem to get the accuracy out of these 85 gr BT's with this 25 wssm Oly k8 upper. Tried 3 different powders, Varget,H4895, and imr4064. Could try 760- idon't know- burns dirty. Hmmm. I wonder about the 100 gr Nosler BT. If it would expand enough for smaller game like coyote ? Maybe the Sierra 87 gr soft point would work. I'm afraid the Horn 75 gr v-max would be too explosive, maybe not. I don't want any bullet skipping, but I don't want any surface splashes either. Considering it will be for 200 plus shots, I got to have 1 MOA if I can get it. Any more ideas fellas ?
 
The 87gr Sierra with a max+ load of Varget shot the best of the lighter bullets in my Oly barreled Dtech, and i tried just about everything!
 
WI3Der, what other bullets did you try? Ever try any Barnes, or Noslers? Just trying to pick your brain to save myself time and money! I would like to try the 80 barnes ttsx.

thanks,
Russ
 
No Barnes, but i did wring out both the 85 and 100gr Nosler BT and just couldnt get the accuracy I wanted. Mine seems to like both the 87 and 100gr Sierras. I may try some more loads once i decide on a trigger fix as I am not happy with the Rock River NM.
 
I got a secret for those RR NM triggers. You need to replace the trigger spring with a jp yellow, and replace the disconnector spring with a regular disconnector spring that has been trimmed a little at a time till you get the 2nd stage pull you want. Mine are perfectly safe and have about 1 1/2 first stage and about 1 1/4 2nd stage. Big improvement.

Leave the hammer spring as is so you still have the same speed and strike force.
 
Just finished shooting a few loads using Reloader 17 in my Dtech 25wssm and can say i am impressed. Not full load development as it is 30 degrees but enough to see potential as all groups looked pretty good. Using Sierra 87gr SPT I worked up to 50.5gr of RL17, 2.270", 3436fps and

I used the 87gr Speer data from the Alliant site.

Varget and IMR4350 is really all i use in the 25wssm, but wanted to give the RL17 a try. Groups definitely are a little tighter with the RL17 over the Varget load I have been shooting, and velocity is up also. I have always tried to stick with the Hodgden Extreme powders but these Alliant powders are winning me over in several rifles both accuracy and speed.

I've got some 87 grain Sierra's loaded up with RL-15, RL-17 and Varget. I hope to get out soon to get some testing going.

I also have some 100 and 115 grain nolser partitions loaded up with IMR 4350 but will wait until warmer weather to shoot those and test them.

I'll report back when I fire these. I could be a while though!
 
This is a great thread!

Just to throw another one on the pile...I've had good results with H4350 and 100gr SMK's out of my DTech with the Oly SUM barrel.

I actually used this load on an antelope at 489 yds this last season, and it performed perfectly. (I only used it because I knew I could hit it very well with this load. I would never reccommend using a match king on a game animal).

I've only shot one coyote with the match kings, and although it put it down right there...it was not very fur friendly. I'm waiting to see how the 87gr SMK's are working for you guys.

I love this forum, hope everyone had a Merry Christmas and has a Happy New Year!
 
I was able to shoot some 87 grain Sierra Spitzers yesterday. I had the same experience as WI3Der. I only loaded up to 50.0 grains of 50.0 RL-17 and was able to hold a 1/2" group with a flyer. They shot great out of a cold barrel as well as warm. I have a bit more work to do but this load combination looks promising and will most likely make me happy.

I also tryed the 87's with Varget and RL-15. Both of these powders behaved like they did with the 75 grain vmax pills (over 1"). I plan on loading more of these 87's and I will try some 75 grain Vmax bullets with the RL-17 powder.

Varget and RL-15 just seems to be too unpredictable in this barrel.
 
Ok, finally have some real results to share. It looks like RL 17 will be a winner with both 100 gr and 87 gr Sierra fb bullets, cci 200 primers.

I was fighting a little cross wind today, probably 12-15 mph. Temp was 25 degrees, and sunny. 22" Oly SUM Dtech 25 wssm.

The very bottom target was interesting. The furthest left shot was a fouler and a sighter, as I was also sighting in the scope a little, as I had it off the rifle. Then I adjusted the scope and shot the next four, first three went into one group and the fourth went back to the left. These were 100 gr Sierras with 47 gr RL 17. Then I shot 2 different groups with 87 gr Sierras, 49.5 gr RL17 is the top left, 49.8 RL 17 is the middle right group.

Then I had 10 more with the 100 gr, same 47 gr RL17 as before. Without adjusting the scope from the first group I got a nice 5 shot group just over .7", the middle left. Also note that it's in the same location relative to the target dot as the last shot from the first group. I overlaid the targets and that lone shot from the first group would have fallen right into this group. So the weird thing is, is that I basically had 4 fouler shots, then the fifth shot jumped about 1.5" left and subsequent groups stayed there.

Then adjusted the scope and shot the last 5 100 gr Sierras, top right. They went into a nice .7" group also.

Oh, the little 3 shot group was just under 1/2" with my 223 AI AR with the Remington sps take-off barrel. Just verifying zero. When I get this Dtech to shoot like that AR does, I'll be happy.

All in all not bad for the wind I was dealing with. Now to verify and improve.

RL17 is the only thing I can get decent speed out of. The 100's clocked 3150 avg with the 87's going 3360 fps. Every other powder is 100 to 150 fps slower.
