With 105s and a 19" barrel, I was a comfortable 3300fps....and what is your recipe? Brass, COL, powder/charge, and primer? I have a 25-284, and am curious where it stacks up to the 6-284. I'm running a 22" barrel with 134 ELDM over 54.5 grns of H1000 and should be around 2900 MV, but still need to chrono.
Lapua Brass, GM210 primer, and RL26.
When I switched to 115s, I reduced the charge to keep it around 3150 to stay legal for shooting matches.
When this barrel is toast, I will likely rebarrel to 25x284 now that there's a good option of high bc .25 cal bullets. (and I have plenty of more efficient 6mm rifles now)
I feel like the 284 case is far better suited for a 130+ class bullet. You're burning a LOT of powder for a 6mm bore.
