Just got a batch of these in from Chinchaga bullets, they are awesome looking little bullets, the BC is estimated at a G1 of 1.000, and a G7 of .475.

According to the guy who makes them (It is a one man show at the moment), who by the way was very helpful, and seems like a great guy to deal with, they are 300gr, steel tipped, rebated boat tail Hybrids. The steel tip is a small 14gr weight, and its purpose is to reduce meplat, as there is no way a jacketed bullet could be reduced so small for the purposes of ULD. They are a "hybrid" design, a secant ogive that transitions to tangent.

I picked up 100 projectiles, and they came packaged very professionally, and were in very nice plastic cases with layers of fabric between them, this is the best packaging I have ever seen bullets come inside of. I'm planning on making up a bunch of test loads for my gun and seeing how well I can get these to group whenever I can get to the range next week.

Anyways, just a shout out for what seems to be a great small company. I'll see if I can get these bullets to shoot accurately, and if I can, then I will be switching exclusively to them for my long range loads in favor of my 300gr SMK's, since the BC is light years better in the same projectile weight.

Here's some pics for you fellas!





Projectile comparison... 300gr Chinchaga on the left, 270gr ULD solid copper Lost River Ballistics (out of buisness) in the middle, and 300gr Sierra Match King on the left.


A good comparison of three common precision rifle cartridges and their projectile size... from left to right:
.338LM : 308Win : 223Rem : .338 : .338 : .338 : 308 : 223


Here is an old price list, but as you can see, the prices are not cheap, but considering the quality of the projectiles you are getting, they are fairly priced.
 
And your welcome for letting you know about these lol. I have yet to pick some up myself. But now that I'm back to work I will be buying some. Kevin you'll have to let me know what load you come up with as we have the same rifles
 
I have personally shot 10 of dales 308 bullets into a pop can end at 800 meters (880 yards for us old guys) with cusotm gunworx as my witness, they shoot very well, i need to order some,

I think the owner is having a knee worked on this spring so get your order in now, he may be on the couch for a month or so I am not sure how long the healing process is and after being on the couch for a couple of weeks he might just like it ; ' )

Speaking from experience Jeff??? LOL - I bought and tested the 308 205 gr, but back then it was aluminum tipped at 196 gr - shot great and the bullets had a consistent weight. Only issue I had was thinking about buying and shooting 3000 a year ... the wife might notice the uptick on the consumables expense ... Bergers are bad enough, especially with the re-emergence of the Canadian peso, but these are worth the money if you are so inclined.
 
Thank you to the OP for this heads-up! Does he have a website or just email contact only? Where can I get a current price list?

I would like to try some of their .308 175gr RBTULDCT and perhaps others. They are not that expensive for a quality bullet - I pay at least as much for Berger .308 175gr Match VLD Target

Also, I see that they list Match Bullets in .277 which is something of a rarity. I have a friend who would like some "accurate ammo" for his .270 Winchester to see what it can do...

No problem, I'm all about passing good press on for people who deserve it.

I'm in the process of dumping powder charges for about 35 test cartridges, 7 different loads of 5 shot groups, with 3 styles of primers, and some various powder charges with the primers that I expect to work the best (CCI magnum) and I will post up the results when I get a chance to shoot them, hopefully early next week.

PM Chinbullco on CGN, he is the man that makes them.
 
I have had he pleasure to Assist Dale make some of his bullets in the past!

He is very particular in his setup! I really enjoyed making bullets like that! Very interesting!
I hope to get a chance again this year to try it again! There is more work to building his bullets than some realise!
Lots of steps.

He sent me some pictures of some SERIOUSLY big 7MM ULD Bullets! He was experimenting lets say! His bullets certainly DO shoot!

He is a great guy and has a great sense of humour!
 
Got a bunch loaded tonight... just beautiful to look at.

I seated them as long as possible while still allowing 100% mag function, because I hate single loading from a repeater. Got them pretty darn close to maxed out!

Video and pics.


Some required modification to the seating die. The tip of the projectile bottoms out before is is fully into the seating cup on my dies, so the manufacturer recommended to drill out the cup using a 1/8" drill bit. Easy as pie if you have a drill press or a mill.






Proper fit of the projectile into the cup, notice no gap or wiggle room at the joint.






Snug as a bug in a rug.


Loaded to 3.680 out of a mag that has a max OAL of 3.775, but they feed reliably so I am happy with that.



Mmmmmm.... that is perfection.

Very nice! They do look and shoot great!

here is a picture of a 155 grain 7mm, 155 grain .308, and a 176grain .308 bullet, and a 338 cal. bullet (I cant remember the weight) that Dale made.


Here is some 176 grain ULD's in my 30-06. Great shooters!
Hope you like the pictures!


 
Ok, shot a bunch of them off today, all of them were pretty darned good except for the first test load which my gun absolutely hated using Winchester primers, and that grouped about 2 MOA. Not sure if there was another factor involved, but I am sticking to the CCI primers, because I got pretty good results with them.

All targets were shot 5 times at 200 yards from prone off bipod and rear bag. No mechanical rests or vices used.

Best groups of the day were with CCI primers, and between 88.0 - 89.0gr of H1000.
OAL: 3.680

I want to test a few more in this powder range, but I am happy with the at worst MOA groups, and best just breathing down the neck of 1/2 MOA.



Here is 88.5gr H-1000, this was the best of the day, and I am quite pleased with it.



I also want to retest 89.0gr H-1000 because I am reasonably sure I jerked shots 2 and 5 because I was starting to get pretty cold at this point, I had been outside for a few hours lying down in -10 weather on concrete. I think it may have potential, so I'll give it one more shot. I want to see if it was me or the load that screwed with the group.

I have been using some of Dales 235 grain ULD .308 bullets in my 300 Win Mag (2725fps). They fly really well!
My Savage 110 BA allows the long bullets to be seated right into the lands and still feed through the magazine! I still have nearly .075" of length left in the magazine for seating depth.

I wish I had my exact data handy here at work, but I have managed to post groups around 6-8" at 1000 yards, and a few smaller than that. More than sufficient for my purposes!

are the BC confirmed with long ranges drop for the 30cal bullets ? wonder how can one produce a 176gr, 30cal with such a BC !!??
 
The BC will not come out at 1.00. That would be nice if it could! Lol!
The bullet would have to be at least 250+ grains for this to even approach that value. I have been using .386(G7) value for my 235 grain ULD's. I am going to need to do some more evaluation of this value to prove it. It may be around .390 (G7), which is very good!
I have to figure the BC's of my 176 grain ULD's when I get a chance.

So much shooting to do, so little time! Lol!
