NOE Clone of NEI 358 282 GC, 300gr Flat Nose?

[35 shooter]

No bullet design shows for me. Does anyone see it?

There's a drawing of it on pg. 2 post #34 in this thread.

Thanks 35 shooter for the location.

yodogsandman.... that bullet looks to me to have an under size nose (on the basis of a 0.350" bore it wouldn't touch much unless it expanded) with a sub 55% bearing length. Most of the accurate rifle bullets I've shot at high velocity have a 65% or more bearing surface on the bullet. IMO this bullet shouldl shoot well at 1800 fps and under with an alloy that will obturate some upon firing.

 

[yodogsandman]

Thanks! How do you feel about the transition from the driving bands to nose diameter?

It's a pretty standard transition. Whether a bullet will shoot at higher velocities or not depends on what the designer did in front of the front band and how well it fits and guides the bullet into the rifling.

Yeppers....and what the bullet is made of so it can handle all that, and what powder/primer is used to push it, etc. so the nose tip, gas check, and lube shanks all spin on the same center after the bullet emerges from the muzzle.

Yep and I'll expand on that to say that bearing surface is your friend whether your looking for high velocity or not. It may be easier to get a bullet with less bearing surface to shoot decent at lower velocity but the more bearing surface the bullet has the easier it will be. The more velocity is increased the more important bearing surface becomes but don't discount it at lower velocities either.

Now that simple statement just made a lot of what i've been researching on design lately become much clearer. Lots of great info in this thread, but that kind of summed it up and really made some things being said here really click in my head.

I can think of at least 5 ways to increase the bearing surface. Increase the diameter at the front of the nose, increase the diameter of the back of the nose, increase both front and back diameters, cast larger by adjusting alloys/casting temp or after casting, by coating the nose with powder coating/Hi-Tech.

What's the most desirable way to increase the bearing surface length for this mold to get best accuracy at higher velocities?

Again thanks! I haven't shot at high velocities enough to form any solid opinions on any bullet designs used for HV. I've only shot maybe 3 designs with about equal success (in my hunting rifles).

 

[yodogsandman]

Ian, I'm all set, thanks. The sky screens are all glued up good. You would have had a good laugh with my first try, after super gluing, I put them together and flexed them a little and they snapped off again! Second time was a charm!

 

[yodogsandman]

Here's the new, improved, modernized version. Much better, in my opinion for HV shooting and terminal performance.

The increase in nose diameter gives great bore bearing surface area for high velocity shooting. This will certainly aid to keep the bullet straight. If there's any concerns about it being too tight, the diameter can just be adjusted by adding pure lead to the alloy to reduce it's size.

The addition of the taper to the front driving band allows the bullet to self-center when fired during initial launch from a stand still. It also allows for a little adjustment in the overall length for tight bores, to keep the gas check even or above the very bottom of the case neck and out of the powder space.

Anytime the metplat of a flat nose is made bigger, I'm in! This FN will create a tremendous shock wave on any game!

Any concerns?

 

[35 shooter]

That should be an elk buster! Don't know about very high velocity with a 310 gr. bullet, but i'd love to try it somewhere from 2000 to 2200 fps. Nothing is going to stand up to it at 18 to 1900 fps. for that matter.

Here's a link to the new NOE 35 Thumper, 360-310 FN active group buy. This replaces the NEI 358 282 GC clone with a more modern and improved version.

Those that sign up during this NOE group buy will receive a 15 % discount on their mold.

Thank you all for your knowledge, contributions and support!

 

[Brad]

It is what we are about.

Be sure to let us know how that bullet shoots. And if you can find a berm that can hold them.

 

[yodogsandman]

Brad, as a comparison, I shot the 35 Whelen yesterday using Lyman 358009's (283gr) over 54.0gr and 55.0gr IMR4831. I tried to recover a bullet from the berm but couldn't. I had my arm up to my elbow and the hole was still as big as my fist at my fingertips. I need a post hole digger!

Still getting nice round groups but, they're opening up, now to +3". I ran out of bullets sized to .360" and am now shooting some I sized to .359". Shouldn't cause much difference, the mold only casts at .358" (HT'd COWW's with 2% Sn).

 

[35 shooter]

Congrats yodog! I see you got your ten sign up minimum this morning. You should have this one very soon...can't wait for a report on it.

 

[yodogsandman]

Thanks 35 shooter!

The minimum orders are in and the tooling has been ordered! Don't wait long if you'd like to get in on this group buy mold for a heavyweight .35 with a big ol' flat nose!

 

[yodogsandman]

Some confusion exists whether this bullet will stabilize in a 1 in 16 twist rifle. Using the following modified Greenhill Formula calculator, this bullet (1.219" long x .360" dia) will stabilize in a 35 Whelen with a 1 in 16 twist at 1800 FPS.

A 1 in 12 or 1 in 14 twist, 35 Whelen will easily stabilize it.

I have a Walt cut NEI version of that bullet..it shoots well in my 1-16 35 Whelen Remington 700.
Mine also has a small nose under .349,but with the long body I have had no problem with accuraccy withe the non bore ride.I have a 35 bump/swager die and have enlarged the nose to .351 but accuraccy didn't change. I don't drive it faster than about 1800 though.most of my liafs are going 1600 fps.I shot it in a cba match 6 years ago and four if my five groups for record were under 1.5".my last group had a wild one that made a 1" group 3+".I love that bullet.

I'd have to check my books but I belive my 357 ruger #1 stabilized it at 1000 fps.
