Home Forums Hunting & Shooting Ask The Gunwriters Powder for .243 & 100gr. Partitions

I just looked at my .243 notes and found a few interesting things. One is that despite Nosler's manual indicating Vihatvuori N560 was most accurate with 95-100 grain bullets, it's been so-so in the several rifles I've tried it in. Reloder 17 and 22 have been very good in a couple of rifles, but doesn't have the consistent track record of the 4350's.

So far the "voting" (which is what these threads usually are) has gone like this:

7828�1
785�1
IMR4831�1
RL-17-1
RL-22�2
Varget�2
H4831�3
IMR4350�4
H4350�6

Make that :

H4350-7

ok, I'll be the outlier. I have an old 243 that loves 4320 and 100gr Solid Bases...and nothing else that I have found.

Imr4350-5 41.3gr. And 95bt's

My 100-gr Partition box states 38.0grs IMR-4350.

Have only killed 1 deer with that load, a 3 pt, it was a beauty too, he fell in the 2-track running through a chop field and I backed the truck right up to him.

MD, in regard to R17 being very good in a few rifles-good accuracy, velocity, both?

The best was in a Browning X-Bolt, groups around .6-.7 with 100-grain Partitions at around 3100 fps with the maximum load from the Alliant data, 41.0 grains.

Thanks kindly.

I long ago stopped looking for a better powder for the 243/100gr. combo than H435o because it's a waste of time and components.

Add my name to the H4350 list. It works well in both 243's the wife and I shoot.

Thanks for the talley, John. I'm going to load some with the IMR4350 and maybe the 4831 until I can find some 4350 of the Hodgdon persuasion.

I tried some H4831SC with 90gr NABs, but accuracy pretty much a disappointment as was the condition of the two I recovered from the damp clay of the target berm. I know it's a tough test, but one pancaked and totally lost its core and the other looked identical, except that the jacket was coated with lead. The partitions (in other calibers) I've recovered from the same place always had the base intact.

Pappy: yes, partitions are much better for killing dirt than ABs (JK )

This past Friday, I walked into a Clayton, NM gun shop and behold, this guy had a bunch of powder. Nearly dropped by teeth.

Mostly IMR, but a good selection. My bud and I got several cans of IMR 4350, 4831 and 7828. I can't remember when I last saw 4350 on a dealer's shelf, any version. He laughed when I asked about Varget...

You just never know where you're going to find some powder.

Good thing too as those berms will charge at the drop of a hat.

In my opinion and experience, H-4350 is the cat's meow for 100gr/243 and 165/30-06.

Gotta watch them berms what got teeth...

I shoot 42grs of H4350 with a 95gr Nosler BT in my rifle. Good accuracy and velocity.

I tried H4831sc with the same bullet, but both the accuracy and velocity were inferior to the 4350. As many have said, it seems to be THE powder for a .243.

I hope that proves to be the case for my Sako as well, as the last thing I want right now is a rifle with "issues". I loaded up some with the IMR 4350 I have and if things go well, I'll go on the prowl for the Hodgdon, as most here think it has the edge.

Have you tried the 4831sc in anything else? I am wondering how it compares accuracy-wise to the real stuff.

One would think Hodgdon has the edge on temp stability. IMR and H versions of 4350 perform pretty close, IME.

You don't see many rounds with such a consensus for a certain powder, as the .243/100 gr. and 4350.

Seems so DF, but if they used 7828 worked out to max with accuracy they would forget all about using 4350. Magnum Man
