Thread: 180gr eld M from a 20" 284win

162s should work well, try changing powder and depths. RL26 works well in shorter barrels, I started using it in my 20” 280ai and am getting close to rem mag speeds with 162s

Superformance is double based. It's going to be more temperature sensitive and is not going to give as good extreme spreads and standard deviations as something single based.

20" 284, I used to get a steady 2590 using AR2213SC, or a twitchy 2750 using Re26.

I use Superperformance in 5 different calibers all give SD in single digets with great accuracy

All the same, I bet if you were to try it across a wide range of conditions, different times of year, with a good chrono, and decent sample sizes, you'd see an improvement to ES/SD with something made by ADI.

I have tried most ADI but have found their slow burning powders lacking in performance the only powder that I found better is RL 26 but I couldn't justify the extra cost.

Recently had similar issues in my mates prc and my 284.

Mates prc with superformance gave similar results to what you have got. Tracked down some rl26 problem solved. ES 6 and half moa.

My 284 with 162 eldm and Rl17 again similar results. Impressed by the rl26 I have some rl16 loaded up and ready to try.

Hi Bobba that gives me some sort of comfort.

What I've come to the conclusion of is Instead of a COAL of 3.252 I'll seat them to being a COAL of 3.200 and see where that gets me. They are currently at 10 thou jump with the COAL of 3.252

I'll drop the powder charge down to 53.0gr due to increased pressure and just group it and see how that goes. If it tightens up then I know I'm heading the right way, if it doesn't well it's not seating depth per se

You mention dropping the powder charge due to the "increased pressure". Where are you expecting the increase to come from?


I have a 7mm/300wsm bartlein barrel that likes 175gr eldx but as much as i want it to like the 162gr eld-m it just wont shoot it better than moa. In your case I'd just go straight to trying a different pill like the 175 or 180gr like you mention instead of persisting with the 162.

Yes, don’t change the powder charge while playing with seating depth. Alter one variable only.

I’ve got 165 grain tgk’s that my rifle won’t shoot that you can try. Yours might like them. Some reloader 19 and 2209 as well if you would like to try something different

I was using adi 2209 with the 162gr in my 18inch 284.
Can't recall charge weight or velocity but it grouped OK and took more than a few deer and goats before I rebarreled it

If you don't mind me asking what sort of speed vs barrel length your 7mm-300wsm

Its a 2nd hand barrel i recently bought from here. 24",
175gr eldx, 63.5gr Rl26 @2950fps (no pressure signs), 65gr RL26 @3075fps (ejector stamp everytime, load came with barrel but i pulled them all. One had no powder in it ).
162gr eld-m - RL26 @ 3100fps (safe load) @3200fps (hot). Ar2209 59.5gr @ 3007fps. Ar2213 @ 2940fps.
Hornady .270wsm brass necked up.

Something nobody talks about with these types of rifles is correct shooting technique. Do you have other high recoiling rifles that you can shoot consistently good groups with?

Once the recoil goes much above a 308 on a lightweight rifle, you cant just slap it on a bipod and a rear bag and point it in the right direction. Make sure you are good and square behind the rifle and ideally shoot off front and rear bags, gripping the forend and having your hand between the rifle and the front bag. Position should essentially be like unsupported prone, but with bags under your front hand and the rear of the rifle. If you must shoot off a bipod, load it forward, and do it consistently. If you have a factory stock, loading will probably lead to vertical stringing.

Nobody likes having their shooting abilities questioned, but its worth looking into.

I shoot a very light .284 and can clearly see the effect of poor technique when I am not setup properly.

Yes, agree. Correct & consistent shooting position & technique is real important to being able to shoot tight groups consistently. I find if I’ve not been to the range for a while I have to “re-learn” this lesson. And more so when changing between different rifles. I always do my load dev prone off a bipod as this is most likely what I’ll be doing for longer range shots in the field. While you probably have a better chance shooting tight wee grps off a more stable platform like a bench rest it’s not really an aid you can replicate on the hill.
