Hodgdon H4350, Reloader 22, Reloader 17, Reloader 15

I’m assuming Hodgdon and IMR are the same, I’d like to buy 1 lb, or even a partial pound. I’m wanting these powders specifically, since they’ll will cover 2 calibers. Unless you have a better choice and have the powder to sell. I’m reloading 6.5 Creedmoor, with 129 gr Nosler AccuBond LR. My other cartridge is 300 win mag, with 165 gr InterBond Boat Tail.

They are all right next to each other on the burn chart. You should be ok

I’ll do some research on them, thank you Darren!

Be careful. H4350 and IMR4350 are very similar, but not the same powder. A friend asked me about it a few months ago and we looked up some specs on it. He ended up choosing H4350 from research showing a better temperature stability than IMR4350 and R19

Here is some data from Hodgdon:

I see dlbleak posted a capture from a burn chart, but here is another from IMR showing them spread a bit more.

Edit to fix typo

I was only assuming, since some places I’ve search for H4350, they say they have it, click it, and it takes me to IMR4350. So was more of a question. No matter, good stuff, thank you!

I have IMR 4350 on hand, Hornady 9th edition names IMR4350 and H4350 on 165-168 grain, but only H4350 on 178-180 grain. I am loading 180 grain Hornady SST. IMR and H4350 are back to back on that burn chart. So would the IMR work for what I’m loading?
