260 Load Help.. Quick Load???

[novaman64]

Trying to work up some loads for a new 260 rem...

Berger 140 VLD Hunting Bullet

25" barrel
1:8 twist - 3 groove
using WLR primers (if it matters)

I was just looking for some quick load numbers to get me started somewhere. Right now I have 1lb of H4350 and was debating picking up either IMR4831, H4831 or H4831SC... My Speer manual shows that the best velocity with the heavier bullets is with the Reloader 19 or the IMR4831; although it seems alot of people are getting good results with H4831 or H4350...

Anyways, thats why I wanted the quick load data, or some references on where to start....

I ran the different scenarios you had listed and actually the IMR #4831 seems to be the best of your options. I couldn't locate a Berger 140 gr. VLD in the .264 listings,... the only one in that grain weight was a 140 gr. V so that is the one I used in the formula.


Berger .264 / 140 Gr. V
42.0 grains of IMR #4831
Muzzle Velocity = 2779 fps @ 58,138 PSI (MAX PSI = 60,191)
Projectile energy = 2,400 ft. lbs
COAL = 2.800
CL = 2.030
25 in barrel

Hope this gets you in the ballpark,...

Cool, thank you.... Now I need to see if I cant find some IMR4831 from any of the local shops... Then its gonna be a LONG wait for my rifle to get back from the smith..... Errrr, I feel like a kid on Christmas again.....
