Plan on going with 225 SST or Interbond, H4831sc the powder, how much do I need to start and end with for this powder and if you've got a better powder tell me please? Rifle is 700 Rem. Thanks for the help, Jay

I like 70-71grs of IMR-4350 with 225gr bullets. I use a long seated 225gr Accubond with 71.0grs of IMR-4350 in my Sako 75 and get excellent groups and have dropped 1 elk with the load. H4831 should work just fine too but IMR-4350 is my first choice in 338 Win Mag.............DJ

Jay,

I like H-4350 for 225 Nosler Accubonds and 250 gr Nosler partitions. H4831SC did not provide the level of accuracy or velocity that the H4350 did. And like djpaintles, I have found the 225 gr Accubonds to be very accurate. The best accuracy for my rifle (Ruger 77 magnum). For this catridge/rifle IMR-4350 is my second choice.

-load data is;
CCI-250 primer, 3.335" Col
RP cases
225 grain Accubond
70.0 gr H4350 = 2755 fps
72.0 grains = 2805 fps.

Good Luck,

Another RL19 or H4350 fan, also IMR4831. H4831sc is great when you get to the 250gr.

69.5 gr IMR 4350
225 gr Nosler AB
2750 fps

Excellent accuracy

H-4831 From 60.9 grains to 78.0 grains
Remington 9-1/2M Primer

But I prefer:

RL-25 From 71.1 grains to 76.5 grains
Remington 9-1/2M Primer

AccuBonds are the most accurate bullet that's been down the barrel of my Model 70 Classic.

225gr. Nosler AccuBond

70.5 gr. IMR 4350
CCI 250

Outstanding Accuracy

Jay:
Well, I can't resist sticking my 2 cents in on this one. I couldn't get the accuracy I wanted with either of the 4350 or 4831 powders so I went to Rldr-22. I was using 225 gr. Partitions but they have never been as consistant, accuracy wise as I like. I finally tried some 225 gr. Northforks and now get consistant 1" groups. My load is 70.5 grs. of Rldr-22 and the 225 gr. Northfork seated about 0.010" off the lands. As I recall, the Northforks cost about the same as a box of Partitions so....
I've always been a fan of using a premium bullet on game and think that bullet cost should be irrelevant. BTW, velocity is about 2825 - 2850 from the chrony.
Try some Northforks, I think you'll like 'em.
