Gents, Ladies, Walter?

Since this site seems to be running slow, I thought I start a new thread with more pictures. That way there's not so many pictures to load on one thread. Hope it helps.

Anyhow, it was asked before the shutdown, if the rifling bottoms out in the grooves. Checking several recovered NF bullets, I see that the rifling does not bottom out in the grooves. I'm guessing that keeps pressures down quite a bit, given the solid copper rear half.

Here's the pictures...

tried to get the flash to light up the inside of the grooves
-

370gr with recovered bullet and 325gr with bullet dug out of very hard backstop at range.
-

another view
-

300gr Barnes X and backstop bullets
-

416 Taylor loaded with 370gr NF bullet. After a few days hunting, the shine wears off everything.

I should state again, the backstop at my range is made from gravel and dirt. It's really tough on bullets. I don't try and compare bullets from it, to bullets in animals, just not the same.

Brian,

That must be the std issue Alaskan backstop. The interesting thing is finding bullets that were shot during the winter into snow and ice, as they often have little damage to them.

Hi Brian,
What does the grooved section of the bullet measure compared to just ahead of the grooves? I guess what I'm asking does the front section of the bullet seal the bore. They look like a real nice bullet. Have you heard any further information about future calibers?

Hi.
My personal experience with test-shooting bullets; is that the best is if you can fire them into ice (or water.It's the same in those velocities I think.)
I've done a lot of those testings during the winter here in Norway (Are'nt we lucky to have those cold winters??) [Razz] .
I usually find a place there the water comes out of the ground / rocks, where it's mountain ground.
Just one warning....you'll get a hell of a ice blast into your face if you're to close!! [Cool]
It's fun though. Specially with my 460. [Big Grin]

470 Mbogo,

I just miked the bullet above the top groove. It is indeed .416" at that point and slightly above.

I'm not exactly sure where the bullet changes from "bonded lead core" to "solid copper". Looking at the pictures of the recovered bullets, I'd say it's somewhere around the top grooves though.

The boxes of bullets do come with pieces of paper inside them with this statement...

quote:
North Fork bullets have been tested on pressure recording equipment and it has been found that they require, on average, 3 to 4% less powder to produce factory velocities and pressures. Individual rifles can vary + or -5% from that norm so it would behoove any user of this product to reduce top loads by at least 8% and then work up loads with an appropriate powder from a reputable manual until the velocity equals a factory load, with the same bullet weight, fired from your individual rifle. In this way you will achieve top velocities at safe pressures.
Anyhow, certainly these bullets are designed to handle the pressure challenges, that solid copper bullets present, far better than most. Between the lead core front half, and the grooved rear half, there only exist perhaps (depending on internal design) the small section right above the grooves of "solid copper." Handloaders have been loading and shooting Nosler Partitions, and Swift A-Frames, both with simular "solid copper sections" between the lead cores for years with no problems.

Here's a quote from I got from an early April e-mail from Mike. It has the recent price list and he talks about future calibers and weights.

quote:
Prices for 2002

284-130 $39 284-140 $40 284-160 $40
308-150 $40 308-165 $41 308-180 $41 308-200 $42
338-200 $42 338-225 $43 338-240 $43
358-200 $43 358-225 $44 358-250 $44 358-270 $45
375-250 $46 375-270 $46 375-300 $47
411-300 $48 411-325 $48
416-325 $48 416-370 $49
458-350 $52 458-400 $53 458-450 $54

Haven't decided on the solids yet as I need to do a time study before I
settle on a price but they will be less than the soft of the same caliber
and weight.

I will be adding 458 flat points, in probably two weights. One weight in
348. Two weights in 366. One weight in 423. Two weights in 277. Solids
are planned to be in 366, 375, 416, 423, 458, and 474. Don't think there is
much call for 411 but I will probably work out the program anyway.

Mike
I hope this helps out. Again, I'm not associated with North Fork, nor do I get any reimbursment. Anyone interested in these bullets should get the real first hand info from Mike himself.

(I just got a digital camera, and like taking pictures [Wink] )
