Any suggestions for 6mm AR loads with 90 gr. Bergers or 105 gr?
Preferably with VV N 133,135,140,150 which are on my shelf at the present; otherwise I need to go out and get H 4895.Thanks
 
You can use the same loads with the Berger 90 as with the Berger 105. Here are some loads and how they chronographed in an upper I have:

28.5 gr N540 with CCI BR4 primer and Berger 105 VLD .010" in lands, 2706 fps mean velocity, 18 Extreme Spread and 8 fps Std Deviation

29.0 gr N540 with CCI BR4 primer and Berger 105 VLD .010" in lands, 2755 fps mean velocity, 26 Extreme Spread and 9 fps Std Deviation

26.5 gr N135 with CCI BR4 primer and Berger 105 VLD .010" in lands, 2639 fps mean velocity, 15 Extreme Spread and 5 fps Std Deviation

27.0 gr N135 with CCI BR4 primer and Berger 105 VLD .010" in lands, 2682 fps mean velocity, 12 Extreme Spread and 5 fps Std Deviation

27.5 N135 = too hot a load with Berger 105's

28.5 gr RL15 with CCI BR4 primer and Berger 105 VLD .010" in lands, 2710 fps mean velocity, 7 Extreme Spread and 3 fps Std Deviation

29.0 gr RL15 with CCI BR4 primer and Berger 105 VLD .010" in lands, 2772 fps mean velocity, 6 Extreme Spread and 2 fps Std Deviation

29.3 gr RL15 with CCI BR4 primer and Berger 105 VLD .010" in lands, 2798 fps mean velocity, 10 Extreme Spread and 5 fps Std Deviation

28.5 gr Varget with CCI BR4 primer and Berger 105 VLD .010" in lands, 2688 fps mean velocity, 32 Extreme Spread and 16 fps Std Deviation

29.0 gr Varget with CCI BR4 primer and Berger 105 VLD .010" in lands, 2717 fps mean velocity, 19 Extreme Spread and 7 fps Std Deviation

29.3 gr Varget with CCI BR4 primer and Berger 105 VLD .010" in lands, 2743 fps mean velocity, 19 Extreme Spread and 9 fps Std Deviation

I don't have N140 on here but about 28.5 gr of N140,start about .5 gr lower and work up).
