HERES THE THE SET UP:
27 in lilja barrel 1-10 twist
200 grain accubond
nosler brass
gold match 215 primers
retumbo powder

Since i havent seen the new nosler reloading manual can someone give me the min and max powder charges for this load. ( preferably from the nosler manual) Thanks a bunch!!
 
Nosler isn't showing a load for Retumbo, just H4831SS, AA3100 and IMR7828. My 300 RUM wont shoot Retumbo, but does well with 91gr of RL25.
 
I just shot a load of 80.4 gr IMR 4350 with the 180 AB and got 3- 5 shot groups of 1.5 inches


at 300 yards
 
200AB
Remington Brass
91gr Retumbo / 96gr Retumbo(too hot so I stepped down to 91)
Remington Primer 9.5M

Shoots 0.5 inches at 100yard.

I see two loads. One is 4.5 grains less than the other, but has 125 fps more velocity. Huh? mtmuley
 
I run them out of a 28" 10 twist bbl. It's always been faster than my others.
This particular gun does not shoot the 200 AB as well as the 180 AB, but still acceptable accuracy.
 
Man I didnt think it would be all over the charts like this. the gun gets here this week. the mule deer season is Oct.13 I've got my work cut out. I guess I'll start out at about 91 grs and work up.
 
Start at 90.0 gr... work up in .5 gr increments... and you'll find it somewhere between there and 96.0 gr. Assuming that you're loading at mag length, 3.600 oal.
 
my rifle likes RE 25, 96.0 grains and 180 Accubonds. Much more so than any other load combo including 200 Accubonds and lots of other powders.
