2020年3月30日 · IMR 4350 is a rather "dated" powder that still works well in a lot of cartridges. Too many to name but here are a few that I use it in. 22-250, 243, 257 Roberts, 6.5-284, 270, 280, 30-06, 300 WM.

2008年10月22日 · Re: Hodgdon 4350 vs. IMR 4350 Yes. The H4350 is a temp insenstive powder. From winter time to summer time, you will notice a velocity/pressure change in your load with some of the IMR powders. I love the IMR powders, especially IMR4350. But a hot/fast load developed in the winter time will be a HOT load in the summer time. You won't notice this with …

2014年8月3日 · I've used both in my 6 Creedmoor, and I will vehemently disagree with Dentite, H4350 is faster burning than IMR4350, just shot both yesterday and 41.8-41.9grs IMR produced the same velocity as 41.6grs H4350, results: 41.9grs IMR4350- 3030, 3037, 3044, 3044, 3016. 41.6grs H4350-3037, 3044, 3044, 3051, 3079.

2024年12月11日 · Do you think Accurate 4350 is as "good" as H4350. Could someone substitute one for the other due to their close burn rate? Thoughts?

2013年1月18日 · I was shooting 65.0grs of IMR-4350 with 165gr bullets in my 300WSM.That should make you a good starting point for the 150's.

2013年10月24日 · I stumbled onto a real good deal on a few pounds of IMR 4350, so I grabbed them obviously;) That propellant seems to be more popular for the larger capacity & magnum cases, but I do see 4350 listings for the heavies (190 and up) for 308 Winchester. Considering I live in the flippin desert...

2021年7月4日 · Powders listed for 5 of these calibers is the 4350. 1 powder, 6 calibers sounds like a win-win. Looking through the Lyman's 50th bible, the mid weight bullets say IMR 4350 and it appears the heavy weights suggest H4350. It also claims that Accurate 4350 was created to compete against IMR 4350, but you can't use the IMR data loads.

2012年5月3日 · Saw a few questions on this site about accuracy only load for 308 Win. Just to let people know, for kicks & grins, I tried IMR 4350 for 308 Win, 168 SMK, 26 in, 1 in 12 twist, and got great accuracy even though a tech told me they DO NOT recommend it. I got it from an older Lyman manual.

2009年10月14日 · Re: IMR-4350 Temperature Sensitivity? Some will want to work with IMR-4350. I see little advantage when the same entity, Hodgdon, markets both IMR- and H- powders. The H-4350 is an Extreme Powder, and is also an SC (Short Cut) product, so it already employs measures to alleviate temperature sensitivity, and to improve powder flow in measures.

2012年1月30日 · From looking over the reloading data it seems like the IMR 4350 powder is a very close match to the 4320. It is readily available and it is extremely accurate in my experience and my rifles from 22-250, 7mm Rem Mag, and 300 WM. If you're ever in a pinch it should work fine for most of the calibers that the 4320 works with.
