Re: 6.5/.284 o.a.l.
I have a 6.5x284 290nk. My rifle has a 28"1/2 barrel and it loves the 139 scenar. My O.A.L. is 3.160 and my best group with this bullet is .093 three shot group. I find that V-N165 burns consistantly. My rifle loves 52.5grns of V-N165 and as mentioned before is very very accurate. The muzzel velocity with this load is 3000 fps. My rifle likes the 142mks, however, the scenars shoot better. I also get great accuracy using H4350, 52grns and using the scenar. This powder burns faster and your velocity will be higher. I get 3100 fps with this powder and my best group was .127 three shot group. My bullet is .010 into the lands. I hope this helps. I have load data using the 142mks, so if you need that info let me know. You will love the 6.5x284. It is with out a doubt the most accurate round I have ever shot. I believe it is the best longrange varmint round available if you have the $ to build one. Make sure to invest in good optics, this round is capable of very long shots. Good luck! and let me know if you need more info.
