twist rate for really fast 6mm

[Eric Leonard]

I am going to do a 6mm-06 and set it up for the Berger 105 VLD Hunting orange box bullets and plan on running them as hard as possible,,this will be a hunting rifle and shot very little after load work,,what bore and twist rate will give optimum results??
in my BRDX and 243 I have very good results with .236 bore and 8 twist,,running the 6mm-06 at max velocities//pressures should I consider a .237 bore or an 8.5-9 twist barrel,
I want to be able to run this at full throttle without ripping the jackets off or blowing them up in mid air,can I expect the 105 orange box bullets to take everything the 06 case can put out from a .236 8 twist or do I need to slow the twist a little??

I am hoping to get 3400 fps using something like RL25 ,Retumbo ,RL33 or something along those lines,

I am not worried about bbl life,,after I get it together and a load set up it wont be shot much if any at all,,the rifle is a 700 BDL 25-06 given me about 1976 by my father and has been rebarreled twice and I want to use the better 6mm bullets this time and have several other rifles to shoot now and just want it fixed back up and retired,

for the stability I will be shooting at about 800' ASL in fairly humid conditions,,

I built a 32" .237" barrel, 8" twist for F-Class Mid Range in 6mm Remington. It would safely hit 3400 fps with Berger 105 Target Hybrids and IMR 7828 SSC. It got the barrel too hot for long strings but performed extremely well for ~10 rounds. Never lost a bullet in flight.

that is good,,,I have a couple 6 mm Rem but the Model 7 has 18.5inch bbl and VLS ahs 26 inch 9.125 twist,, I am going with the 06 case so I can actually get brass and if I trash the primer pockets in one firing 06 brass is easy to get,,

my stock is inletted for a Shaw #3 contour at 26 inches and the Bartlien 2B is close as is the #3 but the shaw 1.250 is about 1.3 longer than the 2B or 3 and I am gonna have to have a custom contour bbl made so I dont have to alter my priceless pristine A prefix era BDL Custom Deluxe stock,,

I have a couple .236 4 groove 8 twist bbls with enough rounds to not be competitive but should work fine to do load development and have the load 90% worked up before firing a shot in the custom contour barrel,,and hopefully have the bbl broke in and load development done in less than 100 rounds on the bbl that will actually go on the rifle,,

thanx for any advice from anybody that has a nitrous equipped 6mm,,

I would do a 6.5 Gibbs and smoke those 120 or 140's out there. i built one up over 25 years ago, using 270 brass for a longer neck. Just something else to enlighten you....

8 twist 6-284. Ran 105gr Berger hybrids, amax and smks at 3500 plus without a problem.

The hunting bullet jacket is not designed for that velocity. Best plan on using the target Bergers
