    78 grains of rl19 in a 338 win mag shooting 225 gr AB is a compressed load. Anything in particular I should be worried about?

    that your load is rather stout...:rolleyes: check your bullet creep... if they are loaded for a few days and haven't crept out of the case at all, you should be good to go.

    I'm at 75 gr rl19 with a 225 ab or hdy sp in my 338 ruger#1 and at 2900 fps. I remember the speer manual going to 78 grains with their 225, but I haven't needed to go there.

    I was thinking the same thing about stout I mean. If the bullet doesn't move then they should be good.

    You sir are a very brave man, I just ran several through my ruger m77 with 75g of r19 pushinga 210 ttsx to 2800 ish My groups opened up at 100 yds, but 74g of r19 was putting 3 in a 7/8 group at 100yds. Just be very careful....

    Hey Lefty, you need any .338 WM brass? I got 39 of them I will never need again. Interested in trading for some STW brass or some other brass...Got any .300 Wby or .257 Wby?

    I've got 400 rounds of 7rem brass sitting around waiting to be necked up to 338 when my current 300 rounds or so gets tired. I'll be fine for a good while but one of these other gents could possibly need the brass. I'd talk to the one running the stout load first...:D

    pm me on your stw brass situation...

    I'd worry about damaging the firearm so be darn careful of pressure signs. No pressure signs though and no worries.

    rl19 is slow enough burning the the 338 I'm more worried about getting it in the case than beating the rifle up... It has to be a stout load though as the ab is a rather high bore drag bullet.

    Which will tend to produce higher pressures because of all the surface area.

    Like I said though, no pressure signs, no worries! I don't know how true it is but a friend of mine with about 50 years of reloading experience told me once the advantage to compressed loads is that as a rule ignition is slower and you get more burning down the barrel than in the chamber/case and as a result you get lower pressures. I've always though tried to ensure I had at least 2-3% of my case capacity remaining.

    Of course back then I was using faster burning powders for the most part... . I also learned the hard way that a case not filled enough can cause extreme pressure problems in a hurry.

    The guide also uses 225 speer sp not AB. I have a few different loads that are up there but the 78gr just stood out and got my attention from memory. Just don't want to see or hear of someone getting hurt. I'd also work up as mentioned with eye on pressure signs.
