Ray,

What is "ringing" in a barrel?

I have loaded for a 700KS in .270 for many years. A max load of 3031 behind a 110 Sierra shoots into much less then moa and runs 3350fps out of a 24" tube. Whats not to like?

This statement quoted below by Ray Atkinson is wrong.

I have used IMR's 3031 since 1953. I have won many target matches with my 40X match rifles shooting IMR's 3031.

The barrels lasted for a long time and best of all it's reliable and I won the matches.

I use it for 358 Win with 200 gr bullets too in my BLR.

How is 3031 outdated?

It's lasted longer than he has, his post is 6 years old.

It may not feature some of the technological advances of some of the newer powders, but IMR3031 shore makes my .30-30 shoot good!

I think Ray must've had a brain fart! :-)

Powders being 'outdated' is a screwy concept...

came into some pull down pre WW 2 vintage IMR 4895, from ammo I disassembled.. dates on the cases were from 1936 to 1941...

tested it out in a 22.250, and compared it to current production IMR 4895....

The 1930s stuff actually shot tighter groups...

if 3031 shot well and performed well in any cartridge you want to choose say from the 1930s or 1950s.. why would it be thought that it would perform differently in the same cartridge currently....

a 30/30 is a 30/30 still, just like an 06 still is an 06, etc...

some think, a newly released powder has to be better than older powders, or they wouldn't have released it...

that is what I refer to as what is currently "trendy" and what isn't...

I'm told on this site that RL 7 isn't a good powder for a 22.250 for example...

yet I still find plenty of data around for it... and it will still perform just fine with highly usable velocity, with bullet weights from 55 grains on down in that cartridge...and gives some of the fastest velocities I have seen with light bullets, same in the 223...

too many folks think if a powder won't yield the fastest velocity possible in a cartridge, then it is either 'obsolete' or its " too fast" to use in that cartridge...

I was under the impression that the original IMR powders were all the same mix, just in different shape/sized granules. I'd have a hard time believing that a sane charge of 3031 ringed chambers with enough frequency to develop a reputation. I've not tried 3031 for reduced loads in anything, as there are better powders for my purposes, like 4198 or 4227. I can't imagine why it wouldn't work with at least 60% case fill though.

I've had good accuracy with IMR3031 with 170's in 30-30, 150's in 308 Win., 300's in 45-70, and 55's in .223. I don't know why I keep looking for something better. Maybe I'm catching the Loonies?

3031 and most of the older IMR powders work just fine; I just don't like how many of them meter.

Even then, they meter well enough to shoot small groups and don't seem to exhibit linear behavior on the chronograph.

If limited to one rifle powder, the reams of data for 4198 on up to 4831 IMR powders brings to light how flexible these single base powders can be.

Bad choice of words.

Single base powders seem to behave more predictably at near max levels than many double based, high nitroglycerin powders.

You would bring the whole "math" thing into the equation.....)(grins)
