Just a quick poll to gauge any potential interest in .475 FN solids from Macifej. Two questions are posed...are you interested? (only "Yes's" need respond, obviously) and what weight bullet would you prefer?


As mentioned in another thread (one I was rudely hi-jacking ), the run would need to be a minimum of 500 peices, and the price of 100 peices (shipped w/in continental US) is $275.

If you are interested, please reply below with your leve of interest (# of boolitz) as well, so we can make arrangements.

To start, I am in for 100 pcs.


Cheers,
Canuck

Question:
Are you interested in a "group buy" of .475" S&H FN solid boolitz?

Choices:
YES!!!
Nah, but they are totally cool

Question:
What weight of boolit would you prefer?

Choices:
450gr
470gr
500gr
520gr
540gr
550gr
Any of the above!!

 

chris,
450, 475, 500, and 520 will be the right weights.. i can't sign up for any of the above as the bullets will be too long

jeffe,

I changed it for you quickly, before there were many responses.

Anyone that voted already, please re-submit your responses.

Jeffe....what is your preferred weight??

Cheers,
Canuck

Since I would only use about 20 in my life my vote means nothing but a 475 grain .301 SD does seem ideal and 500 would be max needed.

Being a flat nose solid what more is needed???

Chris
i voted for 450 ... see Gerard's pics on 400gr .458s in Doug's SD thread. Mac's bullets look great, but I do not think am a player on this one. 450 GR is the right weight here

quote:

450 GR is the right weight here

Gerards pic is of an HV bullet.

I don't agree with your statement above across the board (it may very well the the right bullet for capacity limited cases) -- I am more interested in seeing a run of these done than in quibbling over bullet weight....if going lighter would kindle your interest, I am game.

Where the heck are IS, RGB, RIP, and 470Mbogo anyway? Thought they'd at least let me know if they are NOT interested.

Cheers,
Canuck

Chris,
G sells the 470450FN .. which is probably perfect.

the 400gr .458 is WAY down the chart for me, but looks like it works as an expanding bullet

How about posting a link for us "not in the know rednecks."

I have NO idea what these things are or what they look like.

Here's a photo of the .505 for Gibbs. See the thread in Big Bores for some test results. The .475 has similar proportions.

Chris,
Mac has made two great bullets on his first runs for public consumption. First a .395/330gr and then a .505/558gr Groovy Brass FN Solid.
prof242 and I are hoping for a .395/300-gr Groovy Brass TOBTHP Elk Basher soon.

I have had trouble finding the time to keep up with my "projects" lately and must pace myself on the dollar outlay too.

I would vote for the 475 to 500-grain S&H .475 Solid, but this has so much applicability to double rifles that I hope he will come up with a driving band design that would work in anything.
Like the GSC and North Fork, that are available ... sometimes ... always room for another good bullet.

I think his dense and strong brass would make an excellent drive-banded bullet. He just needs to get over the guilt of feeling like he is copying. Drive bands have been done since BP days.

Some day maybe a 435-grain FN for the .475 Turnbull. Drive bands and a good crimp would work well there too, and would make nice varmint loads in the 470 NE, 470 Capstick, and 470 Mbogo.

You guys are killing me with this driving band stuff!

OK! Here's the deal! Canuck should modify his poll and ask the guys who are in whether they want a driving band or grooved design. I can make either. The driving band is actually less brain damage to make.

So! There y'all go! A 475" brass solid with driving bands.

I have recieved one PM from an interested party that prefers 470 grains, and I know he has both a 470 Mbogo and a 470 NE...so, I am betting a 470, 475 or even 480 gr driving band solid would be amenable to him. (.475, 475gr does have a ring to it).

I could be easily satisfied with that too.

If I modify the poll it will wipe out all responses thus far, so hopefully others will check in and just speak up with their preference.

Also waiting for 470 Mbogo to see this thread and chime in.

Cheers,
Canuck

I'm working on the 475 Grain .475" Banded Solid then as we speak. By the time you get 5-10 guys together I will have it finished.

RIP,

In the absence of Don Mbogo, and since you have a 470 Mbogo, are quite knowlegable on the topic of throat/leade etc, do you have any recommendations on location of a cannelure (or top driving band in this case) for this bullet?

Jeffe, since this could provide fodder for your 470 ARs as well at some point, do you have any suggestions?

Cheers,
Canuck

Canuck,
I would have to get out the JGS reamer drawing and look at the throat. I would gladly do that later this weekend. I assume it is the standard Dave Estergaard throat.

Mainly if it will work in the tight CIP minimum throat for the 470 NE it should work in anything, and allow longer crimping length in the other ones with various freebores.

Just like the excellent S&H .505/558-gr Groovy Brass FN Solid will work in any .505.

Yes I would start by making it fit the 470 NE throat and a banded FN and it will work in any of the DGR bolts and doubles.

HI Canuck,
I'm in for 100 of whatever you guys are looking for. I really like the 540's at 2400 fps with the .410 meplate. But If you guys decide on the 475 grain bullet I'm in on that also.
Take good care,
Dave

Sounds good Dave!

So far that's three canucks in for 100 apeice, and Jim Manion from the other thread for 100 also (assuming he's OK with the weight and driving band concept). 4 down, hopefully more to follow.

Cheers,
Chris

Shoot yeah! If it is just 100 at a time count me in too. You talked me into it. I am a sucker for good bullets.

Excellent RIP. That gets us to the minimum order of 500. Hopefully a few others will still join in too.

Macifej is getting close to a design for us to look at too.

I am afeerd I may have to see it in the AM though....time to hit the rack at this time zone...

Cheers,
Canuck

Carry on guys and try to get a couple more guys on board so I can cover the cost of shipping to parts far and wide. The run will go 1000 pieces then.

Here is the minimum throat to make it work in anything, CIP 470 NE:

G1, start of throat diameter = 0.4764" = 12.10mm
j = leade angle = 0*50'01"
G = throat length (leade only, no parallel-sided freebore) = 0.3528" = 8.96mm

land diameter = 0.4665" = 11.85mm (what the throat tapers down to over that .3528" length of leade)
groove diameter = 0.4744" = 12.05mm

There ya go. That's all Macifej needs to make the nose fit.

Then there is box length, not an issue with doubles.

Magazine rifle box, 470 Mbogo: assume a stingey 3.750", many are bigger.

Case length of the 470 Mbogo: 2.945" max seems to be burned into my brain. Trim to 2.935"

Nose length allowable = 3.750"- 2.945" = 0.805"

470 Capstick similarly: 3.600" - 2.850" = 0.750"

Just make the nose portion .750" long when crimped in the first interband space, and that length includes the width of the first band.

What is the tangent of 0*50'01" in order to figure out how wide the first band can be, or Macifej can do it with his 'puter.
Subsequent bands may be wider.

I vote for a .4750" diameter of driving bands (bullet diameter, bearing diameter, and any tolerance should be +.0005", -0.0000 ), and an inter-band diameter at bore/land diameter of CIP minimum: 0.4665"

The pattern of the driving bands should be numerous and thin with a little more space between the bands than the bands are wide, yaknowhatahmean?

Base of bullet? Flat with radius or slight boattail? FN nose. Brass.

Now the finer details for Macifej.

Thanks RIP! You rock.

Sounds like what Macifej and I have been discussing will work. IIRC, he has the nose (from inside first driving band to tip) at about 0.625, which should give lots of room even for 470 ARs (similar nose length as Swift A-frame and shorter than Barnes X). FN meplat of approx 0.365.

All I know about the driving band pattern is that it is "whacky" The tough material gives him some latitude for larger spaces between. Looking foward to seeing it, although I must sign off shortly.

Hopefully Macifej will cc you on the design for your sharp-eyed critique!

Cheers,
Chris

Incoming!!

Canuck and Macifej,
That nose length of .625" will be good. Those with longer throats and boxes can seat them out, load them long.

That first driving band of full .4750" diameter that is ahead of the crimp should be no more than .0535" in width, or 1.36mm.
1mm band width throughout would be fine.
This will assure that that first band ahead of the crimp will fit even the tight CIP 470NE throat.

I am voting for a simple band arrangement with each band 1 mm wide (.0394" or about .0400") and with 1.5 to 2 mm of space (.0600" to .0800") between the bands ... or a 1/2 mm wide band first and progressively widening the bands until the last band is 1 mm wide and the spacing is constant on the centers of the bands, about 1.5 mm to 2 mm apart.

We wait to see what Macifej comes up with. Anything in the 475 to 500-grain weight range would be fine. The more bands the merrier.

Some fancy bullet makers vary the width and spacing of the bands as they progress from the nose toward the base of the bullet. Walterhogs and GSC?

The latest North Fork banded bullets (FP and CP) have a neat arrangement similar to what I am suggesting, with constant band width. Not undersized. Plenty of neck tension and multiple crimping locations.

Ok guys I am back on the case here. I will refine a bit and resubmit.

........Ya a 475 gr weight is great for me ,,,,But I don,t have any 475 caliber rifles yet ???????? .,., Gonna have to remidy that ..

Canuck,

How you coming on getting your .475 - 475 crew together?

I will be ready to get them made early next week.

So far just the 5.

Once your design is settled, I'll broadcast my efforts a little further.

Cheers,
Canuck

I should have it to you this evening.

will they be "Tigershark" banded?

Only the HP's will have the Sharkee Look!

The solids will still be TFN's

Gotta make what the customer wants Boomer!

I'm going to make some .375" Sharkee HP's pending the .395" crews results.

Oooohhh. Hmmm....if they are in the 260 to 270'ish grain area, it would be fun to try them out in my 375 Ruger.

Cheers,
Canuck

Lets just hope the theme music from Jaws does not scare the game away before you can get the shot off...

dun duh

dun duh dun duh dun duh...

Here is the "Sharkee Bullet" Mascott

Looks like a "Grand White" to me, perfect logo for the S&H(ark) Granded bullets. SHark Bullets are SHarp.

Hey! Since everyone and their dog Spot has a .375" of sorts, I might actually be able to do a long enough run to pay for the machine time for all these other wierdo bullets!

Say Maybe 10,000 Sharkee Bullets in small boxes of 50 - 100 each.

Let's see what the Prof has to say when he gets back eh??

Macifej,

Reply sent. Forgot to cc RIP though, and when its gone from hotmail, its gone. Maybe you can FW to RIP or cc him on any reply.

Cheers,
Canuck

Can do!

ok other than having stripes and being aggressive tiger sharks have unique jagged peeled back shape teeth...how appropriate

Nasty looking teeth their Boomer!

Not something I want chasing me around the pool!
