Loaded up some 338 win mag using 225gr hornady with 75.0 gr of RL-19 and 76.0gr of RL-19 have many of you used this load I did a search and found most are using anywhere from 71.0-73.0 gr of rl-19. I pulled this load out of the speer manual according to the manual I'm 2-3 grs from max. Won't know how they shoot until my friend shoots them in his 338 mag. Also what's up with Speer not using Hogdon powder I was hoping to find some load data for H-4831 and H-4350 for the 225gr slugs.. Went to sportsman warehosue and they jack for reloading manuals no Nosler or Hornady manual???

Just yet another example of the differences in different loading manuals. Speer's data for the 225 grain bullets in the .338 Win Mag is a good deal hotter than any other manual around these days.

The reason, I believe, is the short bearing surface of their 225 grain bullets, especially the boattail version. This allows the use of a good deal more powder than with other bullets.

The latest Hornady manual shows a max of 73.3 grains of RL 19 behind their 225 grain bullets while the Speer manual lists 78 grains Max. A big difference, to be sure!

If your friend wants to shoot those loads, I would do so with caution.

I am not sure why you think Speer does not show loads for Hodgdon powders. The number 14 manual shows data for H 4831 and H 4350 both for the .338 Win Mag and the 225 grain bullets.

I am sure the data in the Nosler, Hornady, Speer, Sierra, etc. manuals are correct for the exact components they used to test their loads. If you change things the resuls WILL be different.

Why would you ever utilize a Speer manual to load a Hornady bullet? IMO, the ONLY 2 references to be used with Reloder 19 powder and a Hornady bullet should be Alliant's reloading data and the Hornady manual.

In most cases you'd probably be alright, however, why chance it? I admit that my own loads will, in certain rifles, exceed a published max load, but I am using only the bullet manufacturer's data and/or the powder data, always starting at minimum and working up.

As I stated before no Hornady manual to be found... I used what I had handy and that was the speer manual... I'm sure the loads will be just fine... Alos alot of mauals these are extremely conservative as well... I was just seeing if anyone else out there has used this load combo...

323 - Send me your email and I'll try scanning the 338 page from my Hodgdon manual. I use 225's with 4831. Both Nosler Partitions and Hornady interlocks shoot to the same POI.

Go into my Link above,you will find what you seek.

I have not tried 225 gr, but I have loaded some Hornady 250 grain bullets with 68 grains of IMR 4350 in my 338 wn mag. My gun likes it. The velocity is about 2660 FPS. I have not had much luck with R-19.

Yes the load data I pulled was for Rl-19 and i looked again they have data for 4 bullets in there manual for there GS and and boattail and other data is for the tbbc bullets for those two bullets 75.0gr is max. When I was doing load development for my 323 hollis I used hornady data (338 win mag starting load) for a 200gr Nosler bullets..

I have used the 75 grain charge of Reloder 19 with a 225 grain Hornady and it was accurate and safe. Excellent moose load.

Reloader 19 is my powder of choice with 250 grain Partitions as well. The load given on the Alliant powder website works well and meets the stated velocity.

Thanks Walter...

323- I just checked the link that blackbearhunter sent you. It contains all the same data as Hodgdon's reloading manual. Since it's all there no sense scanning and sending my manual pages.

I used them on one extende plainsgame hunt in 1995 I think..I also have used several other 225 gr. 338 bullets. My opinnion on the .225 bullet is that it is neither fish nor fowl..I don't like them particularly well..

I have had much better luck with the 210 Nosler at 3005 FPS and the 300 gr. Woodleighs at 2493 FPS in my .338..Both of these bullets have killed like the hammer of Thor for me..Mostly I just use the 300 gr. Woodleighs as the kill deer well and will shoot lengthwise through an elk or Kudu..I even shot a couple of buffalo with them, both Bison and Cape Buffalo.

I wish I could get my hands on some 210 partitions... and not pay the 44 dollars for a box of 50 ouch...
