First... I don't reload but my close friend does and we both have .260s
.
.
Second.... Is this a fair price?? 34.99 per 1lb?


Thanks, Slug-O
 
Is there any difference between H4350 and IMR 4350?


I picked up a pound to try

loaded it up the exact same as i do with h4350 in my 6.5 creedmoor 41.6g
It had the exact same poi and the dope matched at every distance we tried
Only thing i noticed, it was alot dirtier than h4350. It kinda looked like the smoke from an old cannon going off lol
 
I ended up at the same load with IMR4350 as with H4350. Same accuracy, seems like the same velocity, although I never shot the IMR load past 400 yards.
 
$25 is a decent price, $35 is way too high. IMR4350 is a very versatile powder, just about right for a .260 with most bullet weights. It's one of the most popular powders out there.
 
Here's my results, I think it varies by caliber.
6XC 105 AMAX

Way expensive, but that's how it goes these days.
I settled on Accurate 4350 when H4350 became rare as hen's teeth.
Accurate 4350 is a good bit less temperature sensitive than IMR 4350, at least according to Hodgdon, plus I was actually able to buy a bunch.
IMR 4350, with some load development, will work quite well in your .260s, but if you shoot at temperature extremes you may see a good deal of MV variation.
This chart shows the MV spread between 0 and 125 degrees F.

I bought 3 lbs of AA4350 after H4350 went extinct. I could never get it to shoot in my 6XC for some reason. 115gr DTAC, 105gr Berger, 105gr Norma, 105gr Hornady all shot near 1 MOA with AA4350, where they are all closer to .5 MOA with H4350 or IMR 4350.
 
I have good luck with it in 6 creedmoor. It's not as stable as H4350. $34 is high here in IN I find it from $23-$26.

I run IMR 4350 through everything I can ! Easy to find and great reliability. I run 30-06/25-06/243/260/300wsm/7mag/280rem and I couldn't ask for better results

I used IMR 4350 in some 6.5 Creedmoor loads as I couldn't find any H4350. The IMR 4350 loads shot exquisitely. If you have Gander Mountain in your area they sell it for $29.99 per pound.
