I don't know a single thing about them.
A 6.5 STW would be pretty sweet.

The barrel will finished at 30" and yes brake will add to that length. I decided to chamber the rifle in 338/300 Ultra. My gunsmith is not comfortable chambering it to 338 Lapua. I could send it out of state but my gunsmith does a very excellent work, so I'll have him do it. Anyway, the two cartridge is almost identical in performance.
DF, how long are you going to have that barrel cut? Are you going to add a brake

Oh yes I can! There's no doubt the STW series of cartridges has more velocity when compared with the equivalent standard cartridges, but when you look at those numbers, you can see that they're not that significant. Let's compare for example the 7MM STW and the 7MM Remington Mag. Using my Nosler #4 Reloading Manual as reference. The 7 MM STW will launched the 175 Partition at 3032 fps on 73.5 grain of IMR-7828. The 7MM Remington Magnum on the other hand can launched the same bullet at 2950 fps on 65 grains of IMR-7828... a difference of 82 fps. Here's the beef. The 7MM STW will burn 13% more powder for a modest gain of 2.7% more in velocity. A case of diminishing return. Now let's look at ballistic. At 500 yards the STW will drop 43.4" from a 100 yards zero and will carry an energy of 1840 ft/lb. The Remington Mag will drop 46.3" and will have 1729 ft/lb energy remaining at 500 yards. A difference of 2.9" in elevation and 111 ft/lb in energy... at the expense of what? heavy recoil, wash-out barrel and probably a bad case of flinching. No! thanks Layne
you can't argue with the velocity numbers those cartridges are capable of putting out.

The problem with a lot of this gun rags is that they have an agenda to sell magazines. In return, they get paid for it, get to hunt for free, and get freebies from manufacturers by pushing their products. If I'm in their shoes, I'll probably do the same thing. Others for reason of vanity, create their own wildcat, to get people excited, and sell more magazines in return. A lot of people will buy into these hype, especially those that are new to the sport. This won't work with the older and more experienced shooter though... who had been there and done that. A lot of these cartridges will weathered away, fade into obscurity, and nothing will be heard of them afterwards.
He's been around the block a time or two so I don't have a problem takeing his word for it,

Parent cartridge is not a right term since the the 338 Win Mag was spawned by the development of 458 Winchester Magnum, which is nothing more than a shortened 375 H&H cartridge shortened to fit the Model 70 action. The 338 Ultra on the other hand, is a totally new cartridge, developed by Remington based on the 404 Jeffry case. Clamp, don't get me wrong here. I'm not trying to be argumentative. I'm just stating my opinion and the fact... that's all. cheers, buddy
As for the .338s, I just threw those in because I know you're a fan of the .338 ultra and thought that showing you that the gains that it produces over it's parent cartridge are about the same as a cartridge that you weren't a fan of.

No worries, I am the king of hijacking a thread. Besides, my question got answered so it's fair game. It looks like Pac-Nor chambers 338 Lapua so I just need to decide what contour I want to go with. I don't want to go too crazy with it as I'll probably take it out to shoot a deer or other critter with it... I can't help but wanting to hunt with what I've got.I am going to do this one slowly one piece at a time, so I won't have it complete any time soon. That will give me time to work out what I want / need.
I'm sorry too Heath.

This is exactly what my dilemma on this build. Weight is an issue but not the deciding factor. This is going to be a specialized long range rig capable of harvesting games at considerable distance. This rifle is going to be fed with a steady diet of 300 SMK. At 2900 fps, the Sierra with a B.C of .780 will remain supersonic up to 1700 yards and still retain an energy of over 1000lbs. With 100 yards zero, it would take 57 MOA of elevation to get there. No coyote will be safe within a mile radius. Heath, let me know if I of any help.

CD, That's still under consideration. I could do either. With slight modification on the 700 reciever I could install Wyatt extended magazine that could house cartridges with an OAL of 3.820. I really like the 338 Lapua route due to better quality brass but my gunsmith never chambered one using the Model 700 Action. He is kind of leery about it. A friend however have a reamer for 338/300 Ultra Mag that he ordered when he built his. Actually the 338/300 Ultra has 3% more water capacity than the 338 Lapua. His rig can easily reach 2850 on a 30" K&P barrel using the 300 SMK without pressure sign whatsoever. I believe I could top that with my 30" Mike Rock Barrel using a much slower powder like he Reloader 25 or the Retumbo. He used IMR 7828. I'll be happy with 2900 fps. I have everything except the action. I want this rifle ready for A zone opening day this year.
That will be one helluva rig. Will it be a repeater or a single shot?
