Re: .260 Remington and 130grn. Bergers
From a 26" 8 twist Criterion 260 Rem barrel
Virgin, FL sized Lapua brass
WLR primer
<span style="font-weight: bold">123 A-Max</span>
2.85" OAL (touching lands)
39.3gr Varget (2930fps)
48.0gr H4381SC (3000fps)
<span style="font-weight: bold">130gr Berger VLD</span>
2.94" OAL (0.010" off lands)
43.5gr RL-17 (3000fps)
44.5gr H4350 (2975fps)
All the above data has repeatable 0.5 MOA accuracy...which is about all I'm good for behind the trigger until I send a lot more rounds downrange.
Using the same loads as the Bergers, I'm no more than 30fps slower with the 130gr Norma Golden Target @ 2.865" OAL (0.005" off lands). The Bergers have proven a bit more accurate so far, but my testing with the Norma Golden has been minimal and looks promising. Plus they're $9 per hundred cheaper than Bergers with a higher Litz G1/G7 BC to boot.

Re: .260 Remington and 130grn. Bergers
Thanks. How do you like the H4831 with the AMax's? I thought it would be too slow for the light bullet. I'm getting close to 3000fps with the H4350. I'm going to try messing with the seating depth a little. I have them seated touching the lands now and will try backing them off and try. I've just had really good luck with Bergers in other rifles I thought I might want to try them in my 260.

Re: .260 Remington and 130grn. Bergers
H4831SC seems to work pretty well from my 26" barrel; 48.0gr is lightly compressed with the 123 A-Max but it has low ES/SD. I can put more powder in at that OAL but once I hit 3000fps and good accuracy I stopped development.
I've started using Varget with 123s...velocity is about 2% lower for 18% less powder, and it has proven very accurate.
Tried using 4831SC with the 140 A-Max but more than 46.0gr @ 2.90" OAL it was so compressed I couldn't get consistent OALs; velocity was also lower than hoped at 2760fps.

Re: .260 Remington and 130grn. Bergers
I definitely get better results with H4350 when using 120 grain bullets, and with H4831sc when using 140 grain bullets. So, hmmmmm, uhhhhhh, I guess try them both. However, don't forget VV160, which also might work really well with that weight bullet.
Good luck!
