New Powder Release from IMR for 2007
From IMR - News Release:
Shawnee Mission Kansas, IMR-Legendary Powders, the innovator of super short cut technology introduces IMR 4007 SSC. You may want to get out your chronograph and see the difference this powder makes as it falls between IMR 4350 and 4064. "SSC" or Super Short Cut powder translates into charge weight consistency ergo accuracy. This important feature of 4007 SSC means the powder easily and accurately flows through the powder measure.
It's shortened grain drops smoothly into small case necks making it perfect for classic varmint cartridges like the 22-250, 220 Swift and 243 Winchester. Users of popular big game cartridges such as the 30-06, 300 Winchester Short Magnum and 7mm Winchester Short Magnum can attain top velocities typical of extruded powders, with the precision metering inherent in this new product.
Additionally, the short powder grains permit ideal load density, making top velocities achievable where a bulkier long grained propellants fall short.
Here are three classic cartridges that produce outstanding velocities with IMR 4007 SSC:
* 22-250 Remington 55 grain bullet, 39 grains IMR 4007 SSC=3,786fps
* 220 Swift 50 grain bullet, 43 grains IMR 4007 SSC=3,922fps
* 30/06 150 grain bullet, 55.3 grains IMR 4007 SSC=2,972fps
Look for IMR 4007 SSC in one pound bottles and eight pound kegs at favorite IMR dealers everywhere Spring 2007. Check for complete reloading data late Winter 2007 at imrpowder.com or write to IMR Powder Co., 6231 Robinson, Shawnee Mission, KS 66202.

Ain't it grand...living today ?
I well remember the 60's...we had a half-dozen powders to chose from...maybe 3-4 different bullets to a caliber...
4831 was about 50 cents a pound...and we tried to use it for eberything...
This new stuff looks interesting...so get out the ol wallet and 'gonna try that'....
Thanks, Nononsense, for that heads up.0 -
nononsense,
Thanks for the announcement. One of the things I see that drives me nuts though, out in the public market, is products going to market without proper marketing. Like the frustration of not having a starting point with the WSM and WSSM cases. I wonder why they are waiting until winter of 2007 for load data? I can see it with the short/super short cases where Winchester had to get ammo out there before it could be reloaded. But waiting for info on a powder that is a reloading component is kind of like...why bother releasing it?
All that negativity out of the way, I'm really interested to see what this new powder can do. I have to say also that the super short cut is a great idea. I've used 4831SC and it's much easier to use compared to standard 4831. The next question too is how much are these new powders going to be affected by temperature? I've really come to like using the Hodgdon Extremes for that reason. I vary from the -20's F. up to 90+ F. up here in MN for shooting temps. So, powder that remains consistent is a big deal. I'll be looking forward to seeing it on the shelf.0 -
Thanks NN that is great news! Let the New & Improved Powder Wars begin[:D] 0 -
Sit back and relax. The shooter and reloader should benefit in the long run. +1 on the "let the powder wars begin". Since I have 8lbs of 4350 and 8lbs of 4895 it will a year or two before I really need to buy more powder for the old 30/06 but in the short haul I may buy a 1lb can to try some loads against my known loads of old. I'm old enough to remember the old government reclaimed 4895 that Hogden sold after the war(WWII that is) in a plain white cardboard can simply stamped with a rubber stamp as "4895" reclaimed. Reloaders today are a bit spoiled with the amazing amount of powder, bullets, equipment, etc. tht is available, but I love it. 0 -
The more you describe it, the more it sounds like they renamed 4320- the short extruded powder that fit between 4064 & 4350 in burn rate. 0
