Superformance powder

Hi Guys, Winchester Australia has finally got Superformance powder advertised as available in Sydney. Has anyone got load dater suggestions for 3006 and 300 wm. Everything I can fined says this powder is good for what looks like a small range of specific cartridges and gives a short list of non helpful options even though it seems most popular cartridges are factory loaded with this powder. looking at 180 and 200 / 208 gr bullets. I am going to hunt the Roar for Red Deer 2018 followed by a fly in Sambar hunt on the following August with my Son. I'm thinking on the Sambar hunt I will use the 300 for any ridge to ridge shots in the 200 - 250 m max range that might present themselves and push my Son up front with the 3006 for everything 200 and under. My 300 is a Winchester Extreme Weather and I'm leaning toward the ELDX for both Red and Samba. My 3006 is a Montana Rifle Company XWR and I'm leaning toward the 208 gr ELDM for Red and 200 gr Nosler Partition for Sambar, what do you
recon is the go?.

Re: Superformance powder
Hi Dennis, Superformance factory ammo IS NOT loaded with hodgdon Superformance powder. The factory ammo is loaded with custom blended powders tailored for each specific caliber and load.

Hodgdon's Superformance powder is completely different from normal powders. It doesn't have a fixed burn rate. It has what is called a progressive burn rate and that means that it burns at different speeds at different pressures. That is why it doesn't work in all cartridges, but where it does work it works well. It would be best to say with published loads because as of yet, those are the ones they have tested and showed an increase in performance over other powders.

I have a load worked up for my 22-250 with superformance powder and the 60gr partition. Best I can recall it was mild load, about halfway between book start and book max, where I got good accuracy of about half moa out of a factory savage axis. I did try hotter loads and never got any signs of pressure, but accuracy got worse.
Good luck,
Michael

HI Dennis
Think of superformance as 2213sc with less bulk density, to get best performance you need a cartridge that runs out of room with 2213sc.
The 30.06 with 208grain is one such combination it works well in, start with low to mid 2213sc data.
Be aware that it is a ball powder so it's more sensitive to temperature then your standard adi powders.
It's no good in your win mag as 2213sc is on the quicker side for the win mag.

Nathan if you read this can you confirm start load?
Also any thoughts on superformance with 225grain eldm in a 308?

Re: Superformance powder
Hi Dennis and Thomas, thanks for your input Thomas, that is all correct.

Yes for the .30-06 and no, not ideal for the Win Mag.

I cannot safely advise on mid or max .30-06 data as there is so much to go wrong regarding case (brand) capacity, primer type, throat length, neck tension and scale errors. But as you say Thomas, 2213sc data works for SF in the .30-06 as I wrote in Cartridges Second Edition, using the 220 grain data for 195, 200, 208, 212 and 220 grain bullets. Sweet spots for the 208gr can run from 2600 to 2750fps, a truly outstanding combo. Suggest Win, Lapua or Hornady brass. A standard primer is OK but do consider a magnum for cold highly changeable environments with this type of powder.

ADI Data (again, I cannot condone this):

220gr / AR2213SC (H4831sc) Start 54.0. Max 57.5C.

Thomas, the burn rate is still too slow for the .308 / 225gr. Better to experiment with Leverevolution which is closer to 2208 through 2209 (Varget through to 4350).

Fortunately, its is not so easy to 'blow up' either the .308 or .30-06 as we go slightly slower in burn rate. Its when we accidentally go the other way that things can become somewhat dire (e.g 2206h / H4895 in the .30-06).

As for your bullet choices Dennis, you are on the right track by keeping the weights up. Much will depend on ranges and game weights with regards to how much controlled expansion you need. The closer the shots and larger the animals, the more you need to consider a premium- or failing this, an increase in bullet weight. If you wish to use the Hornady bullets in the Win Mag on Sambar, do consider the 220 to 225gr weights. The 220gr bullet will fit your magazine best while the 225gr will have to be jumped by a few mil.

Note also that the .30-06 loaded to 2700fps with the 200gr ELD-X or 208gr M will produce a good deal of recoil. So you will need to make sure that your son is able to cope with such a load. If ranges are indeed inside 300 yards, there is actually no need to load past 2400fps. Even with its heavy jacket, the X works well from this muzzle velocity when used on larger bodied medium game. The thinner jacketed M works exceptionally well on a very wide range of animals from mild muzzle velocities. So do take recoil issues into account and load accordingly.

Re: Superformance powder
Hi guys, thanks for the information. 2600 - 2700 with 200 gr bullets in the 3006 sounds pretty flash. We have plenty of Hornady Bass. Hornady factory ammo with interlocks are very accurate in both our 300 and 3006 and have worked well on the Does and Hinds we'v shot so far so we stick with the brand. I've been accumulating all the relevant and or interesting components projectiles etc for the big hunts in our plan as supply is pretty unreliable here in Sydney, including a big ass stack of second hand loading equipment. I will add the 220 grainers to the list for my 300 and the Superformance powder for the 3006. I haven't actually started loading quite yet but my Gun Smith is a really cool Guy and has very kindly offered to help me sort out all my loading gear in the next couple of weeks and coach me to tailor up the loads I want for our rifles. My 300 couldn't shoot better than inch and a half when I got it but after he tricked it up I get groups .3 - .45 with Hornady white tail 180 gr ammo. Looks like lots of fun between now and March / August. Recoil won't be a problem, my Son actually learned to shoot on the 3006 and with the straight stock it actually kicks notably less than my 308 Weatherby Vanguard. Thanks again Nathan for that bit of info.
