Thread: 284 Win with Hodgdon Superformance

Hi all,

Just picked up a bottle of Hodgdon Superformance from trademe for my 284 Win built (t3). The load info is bit hard to find, but someone here has mentioned that it has similar performance as RL17. Any chance to share load data? I have few projectiles ranging from 140gr-180gr, also got bit N550 and N165 left so will be appreciated if anyone has load info. I feel sorry for young people just getting into reloading or hunting now days. I have just paid 450.00 for a set of redding die. They all worth of gold now days, if you can find them... take care

Yep, Superformance is a great choice for 284. I use it running 160TMKs @ 2830fps out of 20in bbl. Sweet spot for me was in the 56-56.5 gn range, but work up carefully from lower in your rifle

thanks a lot Chainsaw, will give it a go

there is NO data on hodgdon site for it......

SPF works great in some calibres and not so much in others. Bloody amazing in a 270. When you find a good load, just be a little careful using it in summer, I have found it is somewhat more temp sensitive than others.

Not much info around. on the bottle it gives: 22-250 with 60gr projectile and 43.0 gr charge, v=3738; 243 Win with 75gr projectile 49gr charge, v=3510; 300wsm 155gr a-max with 73.5 charge, v=3405fps. Speed looks quite potent. With Chainsaw's load it looks have similar burning rate as RL17, although it is ball powder so might not as stable

That 60g projectile is fair moving

@hey I’m using R17 in my 18 Tikka action Hardy barrel rifle. I found the best group at 51.5g but it’s not fast at 2726ft/sec with 150 ELDX. I’m very happy with the three shot groups (1/2) inch and it regularly shoots two shots though one hole when I’m checking the zero.
I’ve got two pounds of R26 and if I can be bothered wasting projectiles, I might try that too.
Good luck, I’m keen to hear how you get in. :-)

Yea I think thats right. Tried some in my 6.5 06 and accuracy was fine, velocity ok, but unexpected pressure signs - this was mid January and 30 - 32 deg

Thanks Craig, will do. nice setup you got there. take care

Hi there, I am using 51 gns of N550 with Hornady 154 SPs at about 2940 fps from a Brno 601 and 20" barrel. Shoots them well and they secure game very well - no degrees of dead! This load seems more accurate than R17 in my rifle, no pressure signs (ie I miked all the case webs and no excessive expansion noted), the R17 was up around 3000 fps though, but very happy with the N550 load.

Thanks Ruger7mm, appreciated for that. yes I have found VV serious powder is one of most accurate powders.

This link will take you to a research project a 284 fan (Frailley) in US did a while ago, it is very interesting and a good guide for 120, 140, and 150 grain loads. Also an interesting test on primers. The VV website now has 284 loads as well.

Thanks Ruger7mm, that's an excellent article to read. For such a superlight hunting rifle that 10 shots group is more than impressive.

Update on the 284 project. Got some 6.5-284 brasses and loaded few rounds for ladder testing. I haven't fireformed them as now powder and brasses are very limited. Both loads are close to the land (haven't measured it yet). Below is the result:
2208 with 139 SST: 1,2 not measured. 3: 47 gr=2858; 47.5=2883; 48.0=2889
Hodgdon Superformance with 162 ELD-M: 53.0 gr=2696; 53.5=2686; 54=2763; 54.5=2767; 55=2817; 55.5=2868
Left is 139 SST, right is ELD-M
