    Want to try 230 grain Hornaday ELDX with H-4350. Anyone have a starting load? Will be using federal 215m unless a Magnum primers is not recommended. This will be shot in a factory Remington 700.
    Just need a starting load for the H-4350, I will work up from there, what does the books say is max?

    Are you familiar with looking these up? Reason I ask is that I would think that is almost required reading and research for reloading and I would always look something up vs going off what someone says on a forum.

    Nosler and Hogdon both have data for a 225 gr bullet.

    My books Don’t have anything for a 230 gr bullet. Only 225 gr and 250 gr. And I got bad 300 win mag data from the Hogdon website so I’m kind of leery to pull anything off of their site.
    Starting load for a 225 gr jacket bullet with H 4350 is 63 gr.
    Starting load for a 250 gr jacketed bullets With H4350 is 61 gr.
    I was wondering if there was any more info out there that I don’t have.

    To be honest with you, H4350 is a tad fast for bullets over 200gr.
    If you really want to use it, start at the 225gr data and work up. You may find that you can load right up to the listed max. 5gr is gonna be neither here nor there as I doubt the bearing surface will be longer.

    I would start with Hodgdon data if it were me.

    Cheers.

    I bet if you contact Hornady they will have some data for you.

    There’s also some info on Snipers hide as well with results on the combo you ask about.

    Not much experience with the .338 win, but the research I did on mine lead to 4350, 4831, R-19,and R-22. I was planning on running the 250 or 300 Bergers. I was running a tc encore but never could get better than moa out of the rifle. I really didn’t need a .338 so I sold it in favor of something with less recoil. Good luck

    I have a good load with IMR 4350 with 210NP and 215 Fed.primers. H4350 will probably be more of a stable powder if you shoot in temp swings.

    Klemm,
    More appropriate powders are H4831sc, RE19, RE22 and Supreme 780, which was an eye opener for me. Supreme 780 may not be available anymore.
    I like powders that give 100% case fill. Air space is not wanted.
    The best powder I have EVER used in the 338WM has been RE19 by a long way.

    Cheers.

    I tried RL19 in 2-338wm neither one would go over 2800fps with 210 NP no matter how much powder I put in the case. With one I had to change from a 215 to a CCI 250 primer both shot the same charge of 4350 and 210 NP. One was a Ruger and the other was a Sako both shot .5 m.o.a. at 2980fps

    Interesting, I have 3 338WM’s, a Win Model 70 EW, Kimber 8400 Select and Kimber 8400 Super America. All with 26” barrels.
    All 3 shoot similar loads, 76gr, 76.5gr and 77gr of RE19 respectively with 225gr Accubonds. The EW is the slowest at 2890fps, then the Super America at 2930fps and the Select at 2938fps.
    I rarely use the 2 Kimbers for hunting. The EW gets used often, it prints nice tight groups to boot.

    I have loaded for several other 338 rifles and RE19 has always been the top performer, don’t understand why your would’ve differed so much.

    Cheers.

    We don’t have any experience with 4350, as we use RL 22 under 225 TTSX’s at 2950 fps in my wife’s .338 WM. That ELDX should be a great bullet for “very” long range and decent (acceptable) on deer at close range.
    Our “only” experiences with the ELDX’s were with different calibers....but was shown to be “very” fragile at high velocity impacts. Not our choice for large or dangerous big game! memtb
