Superformance (SF) powder results in a 700 Ti 22" barrel 30-06

Win cases
Win mag primers
COAL 3.450

150 AB S-F powder 67.0 grains
mv 3,110 average

168 NBT S-F powder 64.0 grains
mv 3,000 average

180 NP S-F powder 61.5 grains
mv 2,830 average

Accuracy good?

Looks like I might wanna try some with 155's in both my Mom's 06 and my WSM.

Dober

Mark, the 180's shot great, sub moa, the 150's shot very good, moa, and the 168's were horrible, 3".

In the WSM it's a winner, winner, winner.

Wow. How much powder compression?

None! The 700 allows me to seat long.

Thanks for the post.

I'm also very interested in accuracy findings.

What does this stuff cost?

Never thought I'd see the day you loaded for a 30-06! The world is coming to an end!

Me neither!!

Wanted a light timber rifle for chasing elk that shot 180 Partitions.

Looks like I found it.

Also make a nice backpack rifle shooting those 150's at 3,100.
Heck, I would think that would make a 270 green with envy.

Why does Hogdon only recommend this powder for specific cartridges?

Thanks...


I may need to "get some"


For the boys 30-06s

Very interesting info. Thanks for posting SU35.

I have been asked how I got my data.

http://data.hodgdon.com/main_menu.asp


They list the 30-06 150 Nosler Ballistic Tip at 53,000 psi using 65.0 grains of S-F powder for about 3,100. The 30-06 is rated at 60,000 sammi and 58,000 cip.
The Ballistic Tip and the Accubond are the same size bullet.

I load two grains more but I have a lot longer COAL to make up for it

Is that the OAL your using? That's sitting out pretty far. Maybe, maybe not.

Yes, it is. I could go lower and cut some powder if I was chasing accuracy.

A 30-06 firing a 150 TTSX at 3100 might convince me to move my 300WSM back a row in the safe.

Definitely worth a lb of powder to find out.

Turning the 06 into a little different beast! Right on, that's cool.

Maybe if you were under their load data

I'm glad to see they added the '06 and 280 Rem to the load data. I hope you're not running too hot to get a few extra fps, sounds like some good performance from the old '06.

M1, do you have the Superformance data for the 280 Rem? I'd love to see it.

I don't know why you would even think that?

I am using their load data.

There is no way I'm running too hot.



Here is the Hodgdon data for the 30-06 using S-F.

150 GR. NOS BT Hodgdon Suprform .308" 3.250" 60.0 2850 43,100 PSI 65.0C 3072 53,000 PSI

155 GR. SIE HPBT Hodgdon Suprform .308" 3.225" 59.0 2843 43,400 PSI 65.2C 3125 58,800 PSI


I could go to their COAL length and cut my powder by two grains and achieve the same results. My longer COAL allows me to load more and still be within pressure limits of the 06.

In Hodgdons 150 grain load data there is 5 grains and 9,900 psi difference between the starting load and max load. Thier max load is only at 53,000 psi.

Roughly, but I think a good estimate, if I take that 9,900 psi difference and divide by 5 grains I come up with 1,980 psi per grain of powder.
The difference between starting and max load.

Those two extra grains of powder add me 3,960 psi to 53,000 psi for 56,960 psi in a cartridge designed for 60,000 psi.
Again, add to the fact that I have a longer COAL my pressures
would safely be lower than that.

It's obvious I'm GTG.

It's on Hodgdon's site at the link above:

120 GR. BAR TSX Hodgdon Suprform .284" 3.230" 54.0 3072 48,900 PSI 60.0 3304 57,300 PSI


140 GR. NOS PART Hodgdon Suprform .284" 3.230" 54.0 2905 55,400 PSI 57.0 2983 58,600 PSI

I would venture to say you could push that by an extra 3 grains and be at approx 62,000 psi and pusing 3,200 mv.

I blew a primer years ago and a really stiff bolt once load data for that was actually under a book max charge. Granted I'd substituted a different bullet of the same weight (a lesson in itself) but had worked up to it and shot groups with no problems at all. Whether some variable caused the extra pressure I don't know but things happen and hate to see you damage your firearm or yourself pushing too hard.



Possibly. Normally I'll cross ref. it with QL to give me an idea if I'm around max or slightly above, esp in the 280, and chrony as I work it up. I hate to push things too much myself, maybe I'm just overly cautious, esp with me not being able to at least get a ball park in QL what it may be doing.

I wonder how this powder would work in the 284 winchester, love to try it but don't want to take any risks unless I have some data to go on.

SU35,

How clean is it burning? Seems I remember reading something about it being a bit dirty.

DF

I contacted hodgeon tech support, the fellow I talked to stated that they worked with other cartridges including the 270 wsm but if there was less than a 75 fps increase in speed Hornady would not let them publish the data.

That's news to me and not in my shooting.


I've tried this powder in the 6.5-284. NO GO.

It's pretty cartridge specific.
