Home Forums Reloading Big Game Rifles Accurate 4350?

I haven't been able to find any IMR4350 lately but did come across a large supply of Accurate 4350. What's everyone's opinion on this powder? I've never used any Accurate powders.

I know I'm gonna have to totally start fresh with load work, but I'm sure it should be pretty close and I expect to get similar results.

Works fine for me. I initially picked up an 8 lb keg on sale for $69. I intended to use for practice loads, but does very well in 243, 270 and 30-06. Now I'm on my second keg. I also like Accurate 4064 which has a short cut and meters much better. Generally AA 4350 burns a little slower that H4350. AA 4064 burns a little slower than IMR 4064.

It works fine. I can usually squeeze a few FPS more out of H4350, but the differences are small. The jars I have on hand seem to be a trifle faster than H4350, but there is enough variation from batch to batch that it is probably just normal random variation.

My M700 300 SAUM absolutely loves the stuff. I bought it as a cheap practice powder for bulk reloading. Ended up several rifles really like it.

Another curiousity with AA 4350. Take a look at the Hodgdon Extreme powder examples they published a few years back. Note how AA 4350 worked from 0 to 70. Pressure and velocity actually increase slightly at 0 compared to 70. I'm not sure how that would work exactly but it is in their guide that way.

To me, AA 4350 is slightly slower than H/IMR variety in the catridges I've used it in. The manuals in some cases show a grain ro 2 more AA4350 than IMR/H.

I've burned enough of it that I feel safe saying, its pretty much a cheaper version of IMR4350. I have no preferance between the two.

But H4350 will be the one I keep around in 8 pounders. Cleaner burn, and mo' faster. The only two calibers I really burn it in are the 30-06 and 260 with lightweights.

Dan,

I too use H4350 in the .260, both with 120 grain and 100 grain bullets. I've worried a couple of time that it might be a little too slow for the lighter bullets. Most of what I've read says to use a faster powder for the lighter bullet weights in the .260, and I've wondered if this might be a minor safety concern. But H4350 groups better than Varget with those 100 grainers. What has been your experience with H4350 and the light weight bullets in the .260?
