I have a 1:8 twist 6BR that I would like to use to slay gophers this year.
Anyone recommend a a good bullet for this?
I was thinking 65grn V-MAX but that might be to light for that twist???
I use 60 gr Taipans over 34.9 gr of AR2208 in Lapua brass with BR4 primers for just over 3500 fps to head shoot Kangaroo's out to 300 yards, they make an absolute mess of the heads which are about the same size as the head on a medium dog, to the point that when cut off and turned inside out, the bone fragments and everything else simply drips off the skin.
The 60 gr projectiles do not allow one to shoot the head when the head is below the body-line as they are wont to penetrate through to the body, however less than perfect shots leave the animal miserable and unable to vacate premises, which is desirable so as to minimise unnecessary suffering.
Note that AR2208 is sold as Varget in North America, and 60 gr Sierra's can be substituted for Taipans ( Taipans are Aus $220.00 per 1000 ).
It also should be noted that I am Moly coating my projectiles.
Yes you can use a quicker powder...I use AR2208 because it is comfortable to shoot with and is showing very little pressure in my firearm.
You may find that 1-8 twist is too quick for this weight but until you try them you will not know !
Just a further note, I have not found neither 58 gr Hornady's nor 55 gr Noslers to be as accurate as the Taipans or the Sierra's in the last three 6MM barrels, the same goes for the other Pro Trappers in this area using 6 MM/.243....yours may be different though.
