.300 Win Mag loads...what are YOU using?

I'm getting ready to start reloading for my Remington 700 5R in .300 Win Mag. What are your favorite loads - both in paper punching AND hunting? I have Retumbo, IMR 4831,R-25 and R-19 in regards to powder.
 
Retumbo and the 230s are a good combo. Work your loads. My load is a good bit over max but it runs well. I only get 3-4 loads out of my brass though before the pockets go. The rl25 would work well with 215 and under I'd think too
 
Retumbo, H1000, and 4350 keep my attention in 300 and 7mm mags. I tend to shoot moderately heavy for caliber pills to capitalize upon the higher BC and greater impact momentum, so I run 180-220's in 300wm. Never has made much sense to run light and mid weight bullets in magnum cartridges when a 308 or '06 family case can capitalize on 150-165grn pills, just feels like wasted potential.
 
I agree with varmintterror on this one. My 300winny is in a browning bar and I load it like a hot 06. Babt boy sent me a pic of a 2 1/2 inch group at 500 with a hot rodded 208 amax. I am guessing at the 2.5, it is smaller than the empty case next to it. He wont give up the load which probably means that it is too hot. But I do know that it is norma brass, 208 amax, and 4831, with a 215m.

I run a mk v in 300 as my go 2.

Rem brass
fed 215
75.5g of R#22
180g Ballistic tip or 180g Sierra BTsp
touch the lands with the bullet

150g Accubond will just about shoot a deer in half

150g tipped triple shock is the same length bullet as the 180g Nosler ballistic tip, and I don't think that an elk would stop one.

This load works well in my rifle, work up to it in your rifle.
 
Ive been using H4831 with 210 Grain bergers for F/Class and Deer hunting.
Win Brass
WLR primer
70.5 Grain H4831
210 Grain Berger jammed .005"

This load shot really good in 5 different rifles just had to find the lands and jam them.
5 shots at 600 yards would normally run 1.5-2". 20 shot Group in F/class averaged roughly 6-8" depending on how i could read the wind that day
