Hey all. I've been thinking about taking my long action M700 284 Winchester elk hunting next fall. I have at my disposal some 160gr Accu Bonds and Partitions here to try. Anyone here have any pet loads for the 160gr 284? Thanks!

As always, proceed with caution in working up loads in YOUR gun.

In MY R77 284 Win with a 20" Shaw barrel.
160 NP, 55.0gr R17, 2900fps, less than one moa.
160 NP, 54.5gr I4350, 2860fps, less than one moa.

It is a deadly combo that will knock elk down easily.
I found it to be a bit much for deer.

Thanks! Those are great velocities from a 20" pipe. Mine is a 24" #4 Shilen on a M700 long action. I put her in a B&C Medalist sporter. If it handles the 160s like it does the 150gr I'll be beyond happy.


She's throated a little long to accept the heavier slugs.

She's a natural born killer.

I have gotten very good velocity and good accuracy using H100V and Fed 210 primers and the 160 gr AB. Accuracy with WLR primers wasn't so good. I worked up to their max of 54.0 gr with no pressure signs and was around 2880 fps with a 23" barrel. That ought to do her.

2900fps from a 20" barrel is pretty impressive, thats a bit more than a 7mm-08 with a 26" barrel. I get almost 3000fps with 53.5gr. of Reloader 17 and 162gr. Amax, I load em in a long action as well. Of course, its always a good idea to start low and work up.

Maybe when things calm down I'll pick up a pound of H100V. Powder being hard to find now and all. I see it turns in some good velocities in the manuals. How are you liking the 160gr AB bludog?

160 accubond and 53.5 gr 4831 sc. 2830 out of a 26" barrel. Very impressive.shoots 5shots in .454 c-c.@100 & 1.22@300yrds & 3.87@600 I use Norma 6.5x284 brass necked up but gun shoots the same with win brass.mine likes accubonds .012 off lands. good luck!

Nice .284 it is my favorite cartridge as well. Built one on a Savage action and a Adams and Bennet barrel. It will shooot better than I can, and I love the look that you get when someone who has never heard of it asks what you are shooting.

What's the cartridge overall length with some of those long-seated bullets?

My notes are all out in the man cave,so I'll have to post them tomorrow evening. I can tell you that the 150gr Nosler Ballistic Tip is just flush with the bottom of the case neck,and a 160gr A-Bond is just even with the bottom of the shoulder. This will put me between .008 and .010" off the lands. It took forever to get the reamer,but my Bench Rest buddy slash riflesmith hit it out of the park. We used a no turn neck dimension and she is very easy on brass. In new Winchester cases,the 150 BT over 55gr of RL19 will shoot .4 moa or better with ease. Once fired stuff is a little better. I wish I'd used a lighter pipe. The #4 Shilen is pretty beefy for my taste. I have a T3 here that may be done up in a mountain weight Lilja barrel and the same reamer as this one. I like popping woodchucks with this one and 120gr Hornadys or Nosler BTs. Over 4320 believe it or not.

Here are some of the OAL lengths on the 284s. I'm seating the 140gr Sierra back to 3.060". The Nosler Ballistic tip is out to 3.200". And the A-Bond is 3.220".

I have a Savage 11f that has been rechambered from 7-08 to 284, it has a fairly long throat, most bullets will let me get to 3.125 oal when touching the lands. Only issue is the magazine will not let me go beyond 3.005, can't seem to get 140 gr bullets to do much better than 2885 with 140 ttsx or partitions without a stiff bolt lift, 140 gr barnes xlc's which are moly coated will hit 2960 with 54 gr of RL 17. Barrel is only 22 nches, that mght have smething to do with it, however 52 gr RL 17 with the 140 ttsx will shoot groups around a half inch.

Haven't shot the 160 AB on game. We took several deer with the 7mm 140 gr AB over the past few seasons, excellent deer bullet, that one. And not to hurt anyone's feelings, but I would work up to 55 gr RL-17 and a 160 gr bullet VERY carefully. That might be a little hot. The only load I can find from a verifiable reliable source for the 284 win is Barnes and they stop at 52.5 for 140 gr bullets and 50.5 gr with 160 gr bullets. So just be careful.

Absolutely bludog. That's good advice for all who reload and pass info back and forth. I have a Barnes manual here that runs about 4 grains light overall compared to other manuals. It is however a pre tripple shock manual,so that may explain it. I do know the monolithics require a little different approach compared to cup and core bullets. Be that as it may,that would put your 55gr right on the mark.

Now that's some good shootin' buddy. I have to get mine aired out at the 400 yd line this summer. A local club has deer target shoots at 400 through the summer. 10X magnification limit on hunting rigs. Lots of fun and a good way to wring out some hunting loads. I'd be a happy camper with those groups. 1/2 MOA out to 600 is great for a big game rig to my way of thinking.

RL-17 has only been around for 3-4 years at most. The TSX came out in 2003 or 2004. The RL-17 powder loads I quoted are from their 2010 update and list the TSX, MRX and spitser solids as their bullets. But Barnes limits their COLs to SAAMI max of 2.800" and that could explain some of their seemingly conservative numbers. Just would hate to see someone run out there and load up a too hot 160 gr bullet load and have something bad happen. Because Barnes stopped way short of that value even with their 140 gr TSX.

52 gr RL 17 with the 140 ttsx is my most accurate load, like I posted earlier it is very accurate, just can't get the speed that most others are getting with their 284.

I have a FN built in the 60's in .284 win. My go to load, which is he only load I shoot in it is:
Win. Brass
Win.LR primers
IMR 4350 55.0 gr.
Hornady Inter-lock 154 gr SP

Have taken many Muley, W Coast Blacktails, 1 Clayton, NM antelope, and numerous white tails in AR & TX over the years, it is perfect for this rifle. If I miss, it's not the rifles fault!
