looking for some opinions about this powder.
I am trying to figure out why it is listed in the manuals for a 30/06, but not a 270. also listed for smaller weight bullets in 243, but not the heavier bullets. looking at a burn rate chart( a few of them!!), it is listed as being on the slower side of the powders i have been using in my 270 with no issues.
I am well aware of the thought that if it’s not in the manuals, it will kill you, but let’s ignore that. I’ve been reloading for a long time and have a decent amount of knowledge i like to think!!
Is there any other reason why I couldn’t work up a load with the chrony, watching for pressure signs obviously, and use it in my 270?
I have heard it wasn’t used in some cartridges because it didn’t provide the stated benefits, but I’m not looking for extreme speed. I have 8 lbs Of it and figured i’d try and use it. would be with 140/150gr in 270, and 90/100 gr bullets in the 243.
 
Just because one source doesn't list it, doesn't mean it can't be used in it. It one hundred percent works for the 270, and with heavier 243 bullets.

I haven't had the best of luck with it. But it does start performing very well once it's close to max load. I guess the progressive burning properties of the powder really start to work then. I have had great success with it in my 300WSM and 130 grain Speer hollow points. Just don't shoot that load at a hundred yards at AR500, it zips right through it.
 
OP, Superformance may not be listed in your manual as a preferred or even suitable powder for all sorts of good reasons.

Depending on your manual, when it was printed, who did the testing, and which powders they were promoting when compiling the information from their testing.

Some manuals have obvious biases towards some brands of powder. I don't know, but maybe powder manufacturers/distributors donate powder and information for the testing, or they pay for part of the testing?

If you have Superformance on hand, it's an excellent powder for the 270 Winchester and about 3% slower than H4831ssc, so any loads listed for H4831ssc will be safe in the 270 Winchester.

I won't give you the load I use for my Remington 700, chambered for the 270 win, because it's HOT.

270 Win loads are purposely kept around 50,000 cup in deference to some of the firearms it's chambered in.

In strong bolt action rifles, it's safely capable of higher pressures, but this is just IMHO, and you should use your personal discretion

I like Superformance with bullet weights of 130 grains and higher, because I can get more powder into the case without compressing it, and get higher velocities, with good accuracy. I suggest you use magnum primers for best consistency.

Do not exceed the load in your manual if you have a pump action rifle. Some say not to use it with semi auto rifles, but again, it would depend on the rifle type.

I've seen Model 95 Mausers chambered for the 270 Win, which is pushing the envelope for pressures any higher than those listed in most manuals.

I've also seen M96 type, commercial actions chambered for the 270 Win, and there don't seem to be any safety issues, but they're made in Europe, where the onus is on the user of the rifle to know what it will handle as far as pressures goes, and the rifles are built to safely handle CIP pressure ratings suitable for the cartridge.
 
thx everyone. that’s pretty much what I was thinking, but when i searched, there wasn’t much info, but a lot of don’t use it if it’s not in the manuals. i’ll start low and work up, and see how it goes.
 
Superformance is slower than H4831, look it up on the burn rate charts.

H4831 recipes will be safe in your rifle, even if it's a pump action or semi auto.

Components are expensive and sometimes difficult to find these days. Take an easy and safe shortcut, to a load your rifle likes, by using H4831 data. If you can't handle that, use IMR4831 which is faster burning than either H4831, or Superformance.

H4831 has been a "constant" powder for the 270 Winchester from the mid fifties to now. It's always given acceptable accuracy and good velocities.

What better place to start?
