2010年11月2日 · The H4350 is the most accurate powder in both guns - better than both RL22 (which is a bit faster) and IMR4350 (which is close, but not quite as accurate). I see no reason to worry much about 50 or even 100 fps when shooting a .270 since I don't use it for truly long range shooting - I have a self-imposed 500 yard max - but 55.0 gr. of H4350 ...

2019年3月14日 · In my experience it is as close as two different lots of the same powder. Matter of fact I use the exact same load in my 25-06 and it shoots the same group size over all and to the same POI out to 300 yards which is as far as I have been able to test it. H4350 is a bit slower burning than the others in my experience.

2020年1月10日 · Over 2800 fps with 140/142s (like 100 fps above H4350), and almost as fast as SuperFormance and Hybrid100V for the 147s. What really surprised me, though, is the data for .30-06 - namely, pushing the 208 ELD-M @ 2660 fps w/ 54.2 grains. Hodgdon also lists it as faster than Enduron 4955 and SuperFormance with 180s (and H4350).

2011年12月12日 · I've got a REM 700 24" factory barrell, Choate varmint stock, 6x20 Vortex Viper, and a really lighten trigger. I'm working up a load with H4350, 180 grn accubonds. Anybody have any experience with H4350 vs IMR4350? I use them one antelope, deer, and elk in varying conditions from mid 70's down to about -30.

Re: H4350 and 308 Not the Best Choice, but undoubtedly better than using a mortar & pistle to grind up sulphur, saltpeter and charcoal. Varget, RL15, IMR 4064/4895 even 3031 plus win ball and vita vourhi powders are much better choices if you have access to the powder.

2008年10月22日 · 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 the H4350 powder.

2009年10月14日 · Re: H4350 load work up - 243 Win I was thinking about loading some lower charges at 37gn, 37.5, 38, 38.5, then 39, 39.5, 40, 40.5, 41. Just to be safe, most of the people I have talked to say there load is around 41 - 42 grains, but when I saw that hodgdon's max I gotta a little nervous starting my workup at 39gn.

2021年7月4日 · 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. I have Accurate and IMR 4350, been in the hunt for H4350 for a year,

2012年4月13日 · Accurate 4350 is manufactured at the General Dynamics Valleyfield plant in Ontario, Canada. The same plant that manufactures most of the IMR rifle powders. Accurate 4350 is going to be similar to IMR 4350. If you can find it, it …

2020年1月12日 · H4350 is very temp stable. IMR4350 is not. If you get 1 granule of IMR4350 in a load of H4350 you'll get to throw that piece of brass away when the primer falls out and you might get to throw the extractor or the bolt away too. DO NOT MIX EVEN 1 GRANULE OF IMR4350 INTO AN H4350 LOAD. Ask me how I know.
