Augustus, do you know what standard twist it would take to stabilize these bullets, or does cutting edge have a recommendation.

Re: Cutting Edge 425/13-6.5 Gain twist

Terry keep the information coming.

I'm glad you finally got out and shot some. I see you took the 338/408 barrel off and put the spin-master gain back on. What is the next stage for testing going to be?

Re: Cutting Edge 425/13-6.5 Gain twist

The 425s are still in the testing phase. CE cut these at the request of a customer. Dan sent me a hand full to run through the 6.5 barrel just to see how they acted. The first few shot really well so he sent another batch for further testing.

All I can tell you is they shoot extremely well form the Bartlien 13-6.5 gain twist. They have been fired out of a 7.8 exit twist by the customer who requested them. He was testing them out of a new case he developed and he indicated he had trouble with his dies and is waiting on those to be delivered. He also has ordered other barrels with tighter twist rates.

Bottom line is that no one really knows what the optimum twist rate will be. I have a constant 8 twist barrel I could screw on and see how they do but I hate to tear my rig apart.

As far as I know myself and the other customer is the only people who have fired them. These things are monsters. I have been shooting at a mile and spotting my own hits. When shooting at rocks they make a very big splash. On steel they are harder to spot than an SMK out of my 338/408.

Augustus:

I was comparing what you report with Kirby Allen's 375 Allen Magnum. I noted (for his set-up):

1. "...33" barrel length"

2. "...starting at around 16 lbs ready to hunt with."

If you were to go with a new barrel - knowing what you do now - do you think you'd go with a longer barrel? If so, how long?

How heavy is your rig and which brake are you using?

Thanks.

Re: Cutting Edge 425/13-6.5 Gain twist

Jeff, actually the 338/408 is a whole different rifle, it is an 8500 action, Lawton 9 twist Idaho taper 30 in. In length. It has an A3-5 stock. I like this stock much better than the A-5 that is on the 8000 action.

ELR, I have never tested a 375 with barrels longer than 30 inches, I don't know if the price of eggs would be worth the wear and tear on the hens posterior. If I were to build another 375, it would be a Lawton 8500 action, A3-5 Stock, 30 inch barrel. I have Lawton brakes on on both the 375 and the 338.

I have a 375 9-6 gain twist Sendero taper Bartlien barrel 30 inches in length. I will probably send it off this week to have it chambered for the 8500 action. This will give me a switch barrel rig that I can shoot the 338/408 or switch to the 375/408 with the heavy CE bullets. I had the 9-6 barrel made for bullets 7 calibers in length, the supply of those has since dried up. I think the 425CE will work well in this barrel.

Augustus:

Have you engaged with the "new" Lawton. I've tried repeatedly to reach them via e-mail but received no response. There is no phone number shown.

Their "current" site lists a "Cheytac muzzle brake" on their barrel's page but no pic. Do you have such a brake? If so, any pics?

Thanks.

Re: Cutting Edge 425/13-6.5 Gain twist

I have not had any contact with them for some time now. I had a couple of barrels ordered from back when Bobby was still there. I received them after the shake up, one was exactly as ordered and is a very good barrel. The other was supposed to be a Sendero taper no flutes. It turned out to be 1.350 at the breech and 1.250 at the muzzle. It also was fluted, since it was dropped shipped to my smith it had been chambered and fitted before we found out the order had been screwed up.

I can send you a pic of the brake. There really is nothing special about it and since they are so hard to contact I probably would not even attempt to buy one. You can get good brakes other places.
