How well do Hodgdon's IMR powders perform

Just getting back into handloading and will be doing some long range shooting.


I'd like your opinion and experiances with the IMR powders now available.

Consistency, accuracy compared to other powders, ease of cleaning etc.
 
IMR powders have been winning competitions and setting records for decades. They all do better than any ball powder when suited to their application.

Gross generalization. And the question was aimed, I believe, at how the IMR-branded powders are working after the sale to Hodgdon, which is at least the the second sale from the DuPont days.

Pretty much.
The powders were produced in Canada more recently, and I've seem references to several IMR types now being produced By Thales/ADI for Hodgdon.

Some ADI single base powders sold to Hodgdon use some new methods of production, and the Varget powder has a great rep for accuracy, but I've seen it said that is prone to carbon fouling build up.

My old favorite is IMR 4320.
 
Caveat: I stick to load data and never go over max. IMHO, the powder manufs skew their data to favor newer powders. I notice the newer powders with higher velocities also have higher pressure.

Been using 4064 and 4350 quite a bit where applicable. They are quite flexible if you like to reload lots of different calibers and components.

I prefer R19 and R22 over 4350 for 270 and 7mm Mag for the velocity for my hunting ammo. But I use 4064/4350 with 375H&H, 8x57, and 30-30.

I like the smaller size of Varget and R15 for .223. I think Varget/4064 are the most flexible of rifle powders on the market. I went to R15 since Varget has been so hard to find.
 
I've used 4064 and 4350 early on in my experiments before settling on 4320 for my rifle.
One of those really smoked up the bore, not hard fouling but alot of soft easy to remove soot. Could have been unsuitable primers I suppose.

I'll be reloading for an antique 25-20 Savage as well.
Reckon 4198 would be a good powder?
