Need a little help in deciding on which 6mm. I thought I had a SA remington action lined up, but that fell through.....so, now I have this 27.5" Lilja 3 groove 1-8 twist barrel sitting here. I also have a SA Remington HS stock, but can probably sell it no problem. I was intending on building a 243AI, but now I am between the 243AI and the 6-284. I would use a long action for the 6-284. I was planning on using the heavy 95-105 vld style bullets. Who is getting what for velocity on the above? I am going to test my Dad's 243AI with the 105's and see what it shoots. I talked with Kirby, and he thought 3400fps would be the max in the barrel that I have. Need some suggestions or thoughts one way or another to consider.
