Imr4350 or h4350

[Sitting Bull]

I need some help deciding on which of these two powders is the most effective in both the .243 and 30-06.
I would like to use the same powder for both calibers. Any reason to purchase IMR over Hodgdon? They both seem to be pretty close to each other.
OR... would you suggest 2 different powders and with ones?
Thanks for the help.

I think this really depends on what grain of bullet you plan on shooting in each rifle.

[Dick284]

Too close to call one way or another.
Both will work in the cartridges listed.

Best powder is the one that gives you the best results.

Buy and try, then stock up.

[Sitting Bull]

100gr in the .243 and 180's in the 06. I was hoping not to have to buy both, but that might be the only way to go.

[Dick284]

FWIW, I am more partial to H, than IMR, having used IMR back in my earlier days of reloading. I switched to H when I tried it in my 300WSM, it shot a smidge better with the same velocity as 1 grain more of the IMR.

If you wanna come out to DV I'll give you a 1/2 cup of both to try.

if you aren't target shooting, does it really matter? for hunting purposes, unless you're reaching out there a long way, you don't need a target load.

Thanks for the offer sir, I'll pick up one tomorrow and start. I was just wondering if there would be a preference out there and why.

H4350 because
H4350 is an extruded propellant in our Extreme series that has been one of our most popular powders with shooters for decades. During that time, Hodgdon has modernized H4350 by shortening the grains for improved metering and making it insensitive to hot and cold temperatures.

I would probably prefer H4350 if it was readily available, however it is so popular it is hard to obtain. IMR 4350 WINS in the availability category, so therefore the overall winner because of this factor!

Nice plagiarized reply from Hodgdon's website.

As for the temperature sensitivity issue, I'd wager that 95% of the end users will never utilize the small advantage that the ADI manufactured H4350 would give in varied temperatures.

**News Flash** all powders are effected by varied temperatures, some to a greater degree than others, but they all will perform slightly different over 40 degrees of temperature change.

And with the advant of auto powder despensers the smaller kernel size doesn't matter as much either.

Choose your powder based on what you obtain for results, not by the marketing hype.

[rem338win]

H4350 has always won for me.

Ive used both and in the cartridges you talk about and either will work. IMR is effected by the cold. Over 100fps difference and changed impact going from 25c to -25c.

[Deer Hunter]

Either work well. Try some reloader 17 for an extra 100 fps

or a magnum primer.

[Pathfinder76]

That's a free 100 fps?

Not saying it is, but I may be a few more. Bottom line is you can always hold up a smidge or dial up another 1/2 MOA. Just a simple range observation.

Maybe not 100, but I betcha 50 is free

Of course it is. You do know how to use the knobby thing-a-ma-jigs round thingy's on your scope?......right? OOOOpps. sorry, that might be too much information for a pencil pusher.

[Sitting Bull]

Walked into the store this morning. No H so bought IMR. I am sure I will be able to make it work , if not well I will look for something else.
Thanks for the help. Im still learning and just when I think I am on the right path, something else becomes available or different choices. So many choices.

[petew]

I have used IMR 4350 in both the 243 and 06 since the early 80's and see no reason to change now.

[gitrdun]

IMR 4320 is my got to powder for the .243

[purgatory.sv]

Yes.

It seems to be available when other are not.

Meters well also.

that's what he said.

something something pencil pusher. it's probably a euphemism for something else


oh ps i use imr4350 because it's cheaper and always in stock. it also has never disappointed me

[Dean2]

I use both IMR and H because some rifles had loads were worked up with one and some with the other. They both work fine. The differences between the two are highly over rated. I have never tried swapping one for the other but I bet I wouldn't be able to tell much difference in the hunting guns.

It's a personal jab is what it is
