POWDER PROFILES from the IMR website:
IMR 3031-Recommended for medium-size cases such as the .30-30
and .358, IMR 3031 is also useful for mid-range loads, and
delivers fine results in cases as large as the .460
Weatherby.
IMR 4227-Originally intended for small cartridges such as the
Hornet and Bee, but has proved useful in a wide spread of
high performance handgun loads as well as .410 bore loads.
IMR 4350-A slow burning powder specifically designed for
bottlenecked magnum cartridges; it is the most popular and
versatile of the IMR rifle powders.
IMR 4064-Medium burning powder well suited for a wide range
of rifle calibers. Long a favorite of Jack O'Connor in the
.220 Swift. IMR 4064 is one of the more versatile powders in
the IMR rifle powder line.
IMR 4831-Another powder from the Second World War, this slow
burner made most of today's high velocity magnum cartridges
practical. Excellent in the .264 Winchester, 7mm Remington,
and the .338 Magnums.
As with all of my powder reviews I'll leave the specifics of
how they performed on a load by load basis to the reviews of
the guns and barrels I've tested using these powders. I'll
confine my comments here to a more general nature.
IMR Powder Company makes and sells a wide range of powder
types suitable for handguns, rifles and shotguns. I've used
many of them over the years and in some cases they have
become my all time favorites even tho some of them are not
the subject of this particular review. IMR 700X has probably
been used more by me in loading 12 gauge shotshells for
skeet, sporting clays and trap games as well as for hunting
loads than any other powder. I used IMR 4227 in .410 bore
skeet loads for many years as well as for magnum hangun
rounds like the .44 Magnum and more recently the .454 Casull.
IMR 3031 has so far proven the favorite powder of the
Browning High Wall BPCR I am testing. It has also been used
with good results recently in TC barrels in .30-30 Winchester
and .30-30 AI Calibers. I've probably used more IMR 4350 than
any of their other rifle powders over the years. This one I'm
using in the Rem. 700 LSS Mtn. Rifles in both .30-06 and
7MM-08, the Browning Low Wall .243 and also in the .30-30 AI
barrels and in rifles in .270 Winchester. IMR 4064 is a
relatively new powder to me but has proven excellent in the
.30-06 and I am hopeful it will also in the 7MM-08. IMR 4831
is an old stand by for the magnum rifles which I am not
personally fond of but have done some loading of the magnum
rifles for others and have used it especially in .300 Whby.
and also in a couple of my own rifles in .270 Winchester
caliber where it excells.
As I've said before in other powder reviews, there are no bad
powders on the market today. Each company offers a wide
variety and you just have to try them to see what your
barrels like best with the bullets you are shooting. Each
will have their own preferences. The IMR Powder line has a
lot of good choices for you to select from. I suggest you add
them to the list of powders you try when working up loads for
your guns and barrels. In most any caliber at least one of
them will provide you outstanding results. IMR Powders get a
thumbs up
rating and the Graybeard Seal of Approval.
