    Default Hodgon 4350 for 338 WM

    Do to the apparent powder shortage in this country. I am unable to get my favorite powder( IMR 4350) for my 338 Win mag. I have been watching the shelf at Rayco's here in Juneau for the last 8 months or so and have yet to see it show up. They did have 3 cans of H4350 that I bought today just incase the other dosen't show up in the next few weeks. I have never reloaded with the Hodgdon before. I really don't have the time to work up another load before moose season. I have been loading 69 grains of IMR 4350 behind a 210 TTSX with very nice results. I went with the Hodgdon because I have heard they are very similar to IMR, atleast with the 4350. I have read a lot of positive comments about Reloader 19 for this caliber too. They did have R19 but like I said I really don't want to work up a new load this close to the hunt. Does anyone have experience with these powders and cartridge and have I been told correctly that there is very little difference between IMR 4350 and H4350. Thanks in advance for your time.....

    Default should be good...

    I think our forum gun/handloader guru that goes by "Murphy" uses H4350 for 250 grain bullets in the .338 Win. Mag. I have been shooting RL 19 with good results for several years. I use it for 225 and 250 grain .338 loads. 73 grains is a well known 225 grain charge.

    Default H is just a touch faster than I

    according to the burn rate charts I hit up.

    Never loaded the H version either, so can't help ya there. I do hear the same info you have been given about them being similar.

    I'd back off 5 grains and pressure check working up a grain at a time while shooting over a chrono. one of them should give you close to same velocity as your IMR loads gave. No promise they're gonna group the same, but it'd be a place to start.

    Shot some RL19 years and years ago, but got better performance from RL22. Don't have records for the RL19 loads, sorry. Then just for geewiz I tried IMR 4350, and I'm in the same boat you are now.... looking and waiting for my new favorite 338WM powder with 225's.

    On-line nosler data shows RL19 loads as follows for 225g Nosler bullets. 68.5 @ 2669fps, 70.5 @ 2751fps and 72.5 @ 2832fps with the 2832 being their most accurate loading. Only bad thing about the online version is they don't say which primer they're using. Pretty sure it'll be either the CCI 250 or FED215's. I've used WLRM's and others in the past, but seems to always come back to the 215's for my loads. Nothing wrong with the CCI's or any others, just happens that my gun/loads like the 215's better.

    They are listed right next to each other on the burn rate chart. I would submit that you won't experience any more of a difference than you might between different lots of IMR 4350. My data shows that your load of 69.0gr. is one grain under max I would back off two more to 67.0gr and go from there if it was me, but I think you should be fine provided your original load wasn't running the ragged edge which it doesn't sound like it was...good luck with the moose hunting

    I've worked up loads with H4350 for my dads .338win (225gr Hornady Interbond) and helped two friends work up loads in their .338's as well (one w/ 210gr TSX and one w/225gr TSX). Always had pretty good luck getting a good shooting load with that powder.

    I got this data from the Hodgdon reloading site, they also own IMR.

    IMR 4350 start 65.0gr - 2468fps / max 69.5gr - 2634fps

    H-4350 start 61.0 - 2448fps / max 67.5gr - 2657fps


    The Hodgdon powder claims to be modernized and resistant to temperature changes. The H-4350 should work out very good for you.

    Note: The IMR 69.5gr load claims to be a compressed load, info only...

    No offense but the numbers you just quoted are for a 250 grain Hornady spire point not a 210 TTSX. Hodgdon shows no data for the 210 TTSX and only one Barnes bullet period a 185gr. TSX. I don't want anyone getting confused or mixing and matching data...it's seldom a good idea.

    You are correct, my bad. I load for my Brothers 338WM and use a 250gr Partition with a powder other than 4350. I just went to Hodgdon's 250gr data in a blind fury because I did not fully read the first post.

    The link above will take you to the Barnes site for their info on your selection. Based on the Hodgdon site info for the 4350 powders compared in the same conditions try dropping Barnes IMR data 2.0gr on both ends, (61.5gr - 68.0gr)

    I have shot the 338WM with a 210 Partition and 74.0gr of RL-19 with good results. I haven't tried the Barnes bullets in the 338WM in any combination.

    Not sure if this helps but I load 76 grains of H4831 with a 210gr TSX. About 2950fps.

    I am sure that 74 grains of R19 (225gr Accubond) will net about 2825 or so out of a 338 with a 24 inch barrel and be pretty accurate. Nosler is a little optimistic on the velocity. 74 is safe in the few 338 WM's I load for. I used FC Cases, CCI250's with R19 and Accubonds. It has a BC of over .550 and a great SD of .281. Good luck with your loading, R19 is an excellent powder for the 338. Scotty
