350 gr 375 cheytac bullet info?

[Bravo 4]

Called them a couple years back about making some Lazers for my .408, just couldn't commit to $800+ for some projectiles my rifle may not shoot well.

Understandable

No clue, but with what I'm planning on building it shouldn't hurt much from a 32" barrel. The hamr had a 29" tube by the way.

The top of their spec page says 29" and the detailed section says 25" - "Length: 25.0 in"

BTW, CEB has built customs for me and if they are telling you they have an exclusive with Gunwerks, very unlikely they will duplicate it for a $250 set-up fee or anything else.

$250 Programming Fee That's out of wack a bunch.

Heck yea we will do that too. And we will go one better. If you don't like the bullets we will buy them back.

I looked on yalls website and didn't see a listing for any 375 cal bullets, there's a section for them but it's empty, what all do you guys offer currently?

Well that's just ridiculous if that's true, a case that size needs at a minimum of a 29-30" tube to get the job done efficiently, that's why I was planning on a true 32" finished length excluding the brake.

Hmm. Try it again. There are 12 37cal offerings. In the big heavies the 395g Hammer Hunter is good to go with the Cheytac chambering. The others we are in the process of doing some design work to get more baring surface engagement. They work perfectly with our test rifle which is a 375-338 Lap imp. But it seems the big 150g powder capacity cartridges are creating too much torque and not getting full stability.

We had hoped to be farther ahead on this by now, but I wound up having a back surgery two weeks ago that has set us back a couple of months. Seeing the Doc today to see how much leash he will give me. Hoping that I can start getting back to shooting. Pain free now, just have to get healed up so it doesn't happen again.

Here is a link to our 329g Hammer Hunter. This will not have any twist rate problems and you can launch it as hard as you want.

Oh I was looking on Rocky Mountain bullets website lol, I though that was the name of the company because of your user name, sorry, I'll do some looking on there and see what I can find.

 

[pondskipper]

the 395 and 403 look very promising! I was looking at doing a straight 1:9 twist 5c from broughton anyhow so I think this would be a good combination.

Those are the ones that we will be working on using Roy's 375 Allen Mag to get the baring surface worked out so that full stability is acheived. So much torque with this heavy a bullet with that much hp behind it. The 395g is our original design and has no problems. The others we reduced baring surface for weight ratio. We have some different designs that we will be trying.

Is it possible to load the 395 or 403 to mag length?

I doubt it. They are quite long. Maybe the 395g. What is your mag length and case length?

Steve

 

[pondskipper]

Don't have a mag to measure yet, I'm planning on using the m-300 mag but couldn't find any specs on them as to what the max internal length would be, I also finally got an answer from gunwerks and have 50 377gr mag feed bullets on the way, when they get here I'll post some photos of them, they have the same external shape as the CE 377 but with the sealing band moved forward so they will mag feed. Also ordered a broughton 5c fluted 9 twist 32" finished length barrel that's about 2 months out right now which is fine.
