Yow! 62 grains of 4198 seems like a major overload with 500s in a .458 Win. Max that Hodgdon lists is 58.5 at 51000 psi. | |||

No flattening of primers and no sticky bolt. Cases show no signs of over pressure. I tried 58 gr and 62 gr. Did not chrono them, but no field difference at all. Cobalt | ||

Cobalt, In my Hodgdon reload manual is have as max load in .458 64 gr H4198 at 2072 fps with a 22" barrel. You'll have more velocity with other powders ------------------ | |||

I found IMR 4195 to be a tad faster than H4195. I think H4195 is closer to IMR 3031. Closer to 3031 than 4195. [This message has been edited by Colonel (edited 05-07-2002).] | ||

I will repost this to you 458 winmag shooters. I was reading that Hodgdon Benchmark closely duplicates the burn rate of IMR-3031 with 3 significant differences. 1) Much finer granules (still extruded) 2) 8% more dense 3) Insensitive to temperature variations This seems to be the perfect powder for a 500gr bullet hunting load for the 458wm. Any thoughts? My 458 is having some fine tuning done on it and I plan to try this when I get it back from the shop. [This message has been edited by Ralph (edited 05-07-2002).] | |||

Ralph, I will wait your comments about this new powder. I've a very nice 458 wm and I don't want to take it to Lott. Where in the internet can I buy Swift A-frames 450 gr? Thanks LG | |||

Hello Lorenzo, Swift A-frame bullets are available from Graf's on the web at http://www.grafs.com Good shooting! | |||

I get the 500 grainers going 2100 fps out of my 458 with 72 grains of VV N130. BMG and I were shooting these (and some rather zippy 400 grainers) in my Whitworth this weekend, it does get your attention.... | ||

Lorenzo, Another good source for shooting supplies is Midway. www.midwayusa.com Also when I ordered some of the Wipeout bore cleaner the fellow I talked (the owner I presume) told me he had good luck with Norma powders with the 458wm easily getting between 2100-2200fps(500gr bullets) with no pressure signs. I can't recall the exact powder number but I will try to find the note I made if anyone is interested. I haven't pursued this as I can't find any Norma powder in central Florida even at the gunshows. | |||
