Re: LUCKY.....GROUP......CLUB ( BI - PODS - ..ONLY )


This might be slightly off topic/target, but in referrence to Doc's 95 gr very lucky duckies, and the shooting mentioned in the line-up a barrel having a 1-9" twist, which I understand is the Berger recommended twist, and is often recommended by quite a few others. I talked with Walt Berger, and he seemed to think for an altitude of 1200 feet and greater, the 1-9.5" twist would be optimum if MV is kept above 2300. [img]images/icons/frown.gif[/img] I knoweth not! I'm thinking about a 1-9.5"; you...have any thoughts on that? -- like, 'No, you fool!--don't do it unless you want maximum energy transfer to targets at close-intermediate range.'

Oh, and on topic, the best bi-pod shooting I've done thus far was a .826" at 487 yards; three shots. I don't shoot off a bi-pod often, which is why my skills are less than appealing. Hoping to work a LOT on the ol` standing position.

Howdy Cybra

Walt is a pretty shrewd Dude! Having never tested the 95 VLD in a 9.5" twist I can not answer the question. The 105 A-MAX stabilizes out past 1,200 yds. in a 9" twist, so Walt could be right on the money. Keep in mind that the barrel length and load have a huge effect on the resulting RPM, and could easily be the difference between it working really well out of a 28" barrel running 3,440 fps., and not so well with a 24" barrel running the same bullet 3,360 fps.

Walt and I have vastly different methods for barrel cleaning and care, but when it come to his bullet designs, he is nails.

I have asked Walt several questions over the years, about twist rates with his bullets, and he has NEVER steered me wrong, or given me bad data.

I shoot 175 grain sierra out of my 308 win with Varget and Lapua brass. The rifle is a Robar SR90 with Robar's match chamber, no neck turning required. I do not do much prep work on the brass at all, just load em and have fun.

When it comes to shooting 100 yards I'm mentally retarded. I hate shooting at 100 yards and avoid it as much as possible. I tend to shoot smaller groups at 200 yards.

I'll do between 3-6 shots at 100 and I'm ready to move on, I have noticed that it helps me tighten up my groups if I put a bunch of small dots on the target and go for one shot hits on each dot.

Here's a picture from my last time out. This is a three shot group at 200 yards.

Was the lowest shot in the group your first shot?

The torque definitely affects accuracy more off hard surfaces, that is what drove us to develop a better brake. [img]images/icons/smile.gif[/img]

Re: LUCKY.....GROUP......CLUB ( BI - PODS - ..ONLY )


Do muzzle brakes have a standard thread and are interchangeable? if not do you have to rethread the barrel or custom thread the break for the existing barrel thread?

Is it as easy as take one off and install the new or is it more important?

What is the cost for a anti-torqure brake?

Has this proven to help even at benchrest?

Do you prefer the old style of harris or the new pivot style?

Thank you for your time.
