Thread: Murphy? .338 question

    Default Murphy? .338 question

    What powder would you use in a 23" barreled .338 Win. Mag. shooting .225 grain Barnes X Tripple Shocks? I have been using RL 19 but I know you are fond of Hodgdon 4350. I have been using the 250 grain X for a number of years but I think they quit making that bullet and only make the 250 grain in the Tripple Shock version now. I trust your judgement.

    Default RL-19 and the 338 Winchester

    There are two powders that I have used extensively for the 338 Winchester and it is one of the calibers that I have loaded for many years and used in the hunting fields very heavily. RL-19 is, and has been for twenty years, my powder of choice for 225 grain bullets. The only powders I now use for any bullet in the 338 is H4350, H4831sc, and RL-19. I had an 8# jug of IMR-4831 of a certain lot for awhile and it was some kind of magical powder. I used it with great results in the 338, 7 mag, 30-06 and many others until it was gone. I bought a pound of another lot of the stuff and it was crap! So much difference that I thought it was another powder. Bought a different lot, trying to recapture that old magic and still no joy. I said good bye to IMR-4831.

    One of the few calibers that I have had good luck with in the Barnes bullets has been the 338 Winchester. That is/was the 225 grain XFB with 72.0 grains of RL-19. This gives a velocity of 2800 and change in my 23" or 22.5" rifles. I have notes scribbled in many of my loading manuals with 225 grain bullets that say "this is it" RL-19 72.0 gr, and 225 grain bullets. In my Nosler #5 manual it is marked (by Nosler) as the most accurate powder, it is. This load gives typical velocity spreads of 10-15 fps!

    With 250 grain bullets, RL-19 is still a good powder gives great accuracy but the highest velocity can be obtained with RL-22 or H4831 sc. I have yet to find a 338 that didn't like RL-19.
    Is there nothing so sacred on this earth that you aren't willing to kill or die for?

    Default Thanks Murphy

    I guese I will stick with RL 19 for now since I have so much of it. I have also had success with RL 22. Years ago my old hunting partner had 7 lbs. of H4831 that consistently gave 100 fps mv more through the chrono then 2 other cans/lots of H4831 with the same charge. He said he would give me a can and I told him to keep it and not share it with anyone or give it all to me . He kept it! Thanks for your time. Where is my autographed copy of your book?

    I was under the impression that the TSX was a better bullet that is supposed to reduce pressure and bbl fouling. Is that not true? If anyone wants them, Gator Guns in Kenai has some 225 grain x's in stock.

    I couldnt edit my above post, but I should have written that I bought Tripple Shock XFB, not XFB as written, or original X's as implied.

    It is the new improved version. It still has higher friction than a lead core bullet but less than the old x's. They are still improving them by the way, thus the new MRX.

    Default 338tsx

    You should try the225 TSX, I have found them to be better than the original X bullet and have been able to work up some loads with velocites that exceed what I was able to attain with the original X bullets and as a bonus I have had less copper buildup with longer string.
