Re: 30 WOLF

Because of this issue called CG offset (think bullet imbalance) There are no plans to make P.T. .338 bullets. The fact is that, it is easier to manufacture a .30 cal boatail with exceptional accuracy. I would like to see more choices for .338's.

I think a 280 gr. A-Max would be a great place to start. The powdered tungsten cores are so superior in terminal effect at low impact velocities, I still prefer the 30 cal.

I know that the 30's and the 338's both have enough energy to kill out to 2,000 yds. I also know that the older I get the less desire I have to carry a rifle with a barrel over 32" in length.

There is a law of diminishing returns in effect, when you already have enough power to get the job done. As you increase barrel length, you also decrease accuracy, especially if the overall weight of the system stays the same.

The flatness of trajectory and superior accuracy of the Wolf make it a better tool for one shot kills if you want something that weighs less than 17.5 lbs., will fit in a drag bag and go anywhere.

Re: 30 WOLF

S1, yes that was the question I was asking. Say ranges of 600 out to 1000 yards.

Brent, I thought that I was going crazy [img]images/icons/frown.gif[/img] but, I double checked and there is a 250gr SMK listed in Sierra's 2002 catalog #2650 for the .338. Now I don't have to go to the funny farm [img]images/icons/wink.gif[/img].

S1 how would the wolf perform with a 26-28" barrel? The 280 PT sounds like it would fit the bill very nicely can you push the powers that be in that direction?

These results will suprise you. I can not find a Matchking on Sierra's Web site for 250 grains. But I did the comparison based on a 250 grain projectile in .338 with a b.c. of .600, and I think this is generous.

The numbers listed below are the Muzzle Velocity in feet per second that you must fire the .338 bullet with a b.c. of .600 to equal the Wolf's performance in 3 catagories: ENERGY, DROP, and WIND DEFLECTION IN A 10 MPH cross wind.


600 YARDS

ENERGY - 3,470 FPS.

DROP - 3,250 FPS.

WIND DEFLECTION - 4,440 FPS. FOUR THOUSAND NOT A TYPO


1000 YARDS

ENERGY - 3,710 FPS.

DROP - 3,350 FPS.

WIND DEFLECTION - 4,600 FPS.

The Wolf fires a 253 gr. pt projectile with a b.c. of .860 that rises to .880 at about 600 yds.

At 600 yds. it has retained 3,340 ft. lbs. of energy, dropped 74 in. from the bore line, and only been deflected 11.2" by a 10 mph wind.

At 1,000 yds. the Wolf has retained 2,480 ft. lbs. of energy, dropped 230 in. from the bore line, and deflected 35" in a 10 mph wind.

A practical analysis shows that the .338 could shoot as flat as a Wolf out to 1,000 yards without going too much longer on the barrel. Both cartridges have enough energy at 1,000 to kill deer sized game very efficiently, but the Wolf has quite an advantage, both in energy delivered and terminal effect with a powdered core.

The real dealmaker comes when you have to produce a good shot in the wind. the .338 250 has no chance of approaching the wind performance of the Wolf no matter how long a barrel you hang on the rifle.

Since the NUMBER 1 cause of a miss at long range is wind deflection, you can see why I carry the Wolf when its time to make Ultra long shots, or even long shots in difficult conditions.

There are already 280 and 300 grain bullets, but they are flat base designs and used for subsonic work out of SR-25's. [img]images/icons/smile.gif[/img]

Re: 30 WOLF

Ok, maybe I'm on my way to the funny farm [img]images/icons/frown.gif[/img] . I checked the Sierrabullets website and couldn't find that 250gr MK but its listed in the catalog with a stock #.
Those are some very impressive results. The 280 and 300 grainer that are subsonic, how would hold up at a higher velocity? I know tha you said that you like the big 30 cals, I've always been a fan of the big heavy fast as you can throw it type. Feel that if the wolf can perform very well from a 26-28" barrel that it could be a near future project.
What type of optics are you using or suggesting on the rigs that you build? How fast would you have to push a 300grMk to equal the wolf (if possible) at the 600 and 1000 yard ranges?
How easy is it for the civilan world to get the pts and does one find loading data for it?

Re: 30 WOLF

Texas

The 300 grainer needs to be a boatail, that is more than 2 years away.

The 5.5 X 22 NXS R2 is the scope designed for this system, and is highly recommended.

The 300 MK can equal or exceed the Wolf at close range in energy: wind deflection and trajectory are a different story. DC would be able to tell you how long a barrel is needed to push a 300 over 3,200 fps. and I will bet it is significantly longer and heavier. We just have not built any .338 Lapuas longer than 32".

The .338 will not equal the accuracy of the Wolf, if they were even close accuracy wise to the good 30 cals, their ballistics would allow them to dominate 1,000 yd. competitions. That is just not the case. The better gun builders get the more you see small calibers show up in the record books. As you approach perfection on the gun side, removing most of the "gun induced" error sources, the bigger percentage bullet CG offset is, in the total remaining error. This is where the small calibers have an advantage, and it has begun to show on the record. I believe this trend will continue for paper punchers.


The 28" barrel will loose about 60 fps. with a 253 gr. and about 80 fps. with a 210 gr. bullet.

Powdered Tungsten bullets will be available in the very near future, at a reasonable cost. I will publish the loading data for these bullets when they come available.

By the way, whats a funny farm look like on the inside, my wife says I need to pick a nice one out, and soon. [img]images/icons/grin.gif[/img]

Re: 30 WOLF

Some people call it Texas but, I call it CALIFORNIA [img]images/icons/wink.gif[/img]. Think I'm starting to get it bigger isn't always better!
Really would like to see what one of those pts look like whole and cut in half any way to post a pic or is it sill a little classified [img]images/icons/wink.gif[/img] .
