Blackjack .257 131gr ACE .330 G7 1000yd verified BC.

25 Creedmoor fodder...….

I like that the .25 caliber is getting some high BC attention, but if you have to go the route of a custom barrel, anyway, I’d say that there are still better options. It is always nice to have options, though.

I'm glad the boys are getting into the more expensive long range bullets to poke holes in paper at 100 yards!

.330 G-7 is pretty darned impressive! It won't be 6mm fast, but it will likely be faster than 6.5mm, all coming out of a Creedmoor case.

I don't know what this means.

You don't but a heck of a lot of High BC bullets end up making holes in paper at 100 yards. There is a range near Cresson that goes to 600 yards.

600?! That's amazing.....

The confusion is strong in this one.

Right. That did not clarify anything.

Is any existing .25 caliber rifle twisted enough to sling this thing? Somehow I doubt it.

Exactly. They require a 1:7 or 1:8" twist to work. Most 25-06 or Wby rifles will have a 1:10" twist. It will need a custom barrel to work.

The BC seems very high. So high that I'm doubting it's accuracy. Why? They list the G7 BC of .330. To calculate the G7 BC, sectional density (SD) is divided by the G7 form factor. The SD of a 131 grain, .257 bullet is .283 (.018714/.06604). So, the SD is .283, and using their G7 BC of .330, and doing the math backwards, this tells me the G7 form factor is .857. Most of your high end, super high BC bullets (Berger, JLK, Matrix, etc) run a G7 form factor of about .9 to 1.0. They have taken it to .857. Is it possible? Maybe. But I doubt it. And in a 25 caliber? If so, it would be one of the most picky bullets to dial in. And you should see lots of competition shooters flocking to this bullet salivating at the mouth to go to a 25 caliber bullet in competition. It would be hands down on of the best bullet options on the market for high BC, bullet weight and caliber combination. I've seen these stats before from other companies only to "revise" their BC numbers later on.

Kevin, do you know anyone who has shot these?

It's bc is legit or higher at creed/x47L speeds for everyone who has been running it. That being said the last batch of 115 dtac I got trued out to a .330 running 3080. Now like these 131's they are made by Sierra so qc could vary this a more varying bc but they have a heck of a stock on hand already along with barrels and some reamers.

Sounds a lot like the 170 grain .277 bergers. Good bullet high bc, but no mass produced barrels to stabilize it and few makers making barrels with a sufficient twist. If your going to go through the effort then there may be other better options. If I could have just bought the .277 bergers I would have, but if I have to rebarel my 270 it will be a 280 ai.

The Berger 7mm 195 grain EOL has a G7 form factor of .892. This bullet is calculating out to .857. I'm very skeptical that this is correct for a 25 caliber bullet. And if so, why? Why make this in a 25 caliber? It's a hunting caliber that is branded with poor bullet BC's to begin with. I would LOVE to buy a 25 caliber, 1:7" twist barrel, spin it up in a x47 or CM chamber, and shoot the snot out of it. But I'm not going to take a chance on doing this with someone telling me a BC, which is falsified so often in the bullet industry. If the BC is truly legit, then they have an impressive product. But I'm tilting my head with an eye brow raised, feeling the numbers I'm seeing are not correct. Just my

Winner Winner Chicken Dinner!

If you think about it, this bullet sits about halfway between two pretty good long range bullets the 6mm 115 and the 6.5 147gr which are both touted as very good long range bullets. What I read they are a product of wanting less recoil from a X47 or creedmoor 6.5 case with more splash on target than the 6mm version.

That bullet sits half way between two good ones for those cases weight wise and .o13 inches larget than the 6mm and .007 below the 6.5

I don't doubt the numbers just thinking about a comparison and the guys shooting the 115 6mm and 147 6.5 in competition are often not shooting a factory barrel anyway

No worries but I know more than one person who has ran them and trued out to the advertisement or better. Check them out on Facebook lots of videos and data provided there.

^^I could not have said it better myself.

Take some speed from the 6mm, and some BC, and mass from the 6.5mm, and you may have got the porrage just right.

In my mind, it is a similar scenario of why I like the 7mm-08 and 7mm-08 A.I. so much. Some BC and speed from the 6.5 Creedmoor, and some mass and energy from the .308 Win. Just kind of does everything well.

Let's be real....JG isn't gonna shoot this bullet or any bullet like it...if it doesn't have an "H" on the box he ain't interested...some might call him a W-Hornady

Now, I'm gonna order a quarter bore, and these bullets just to prove you wrong.

This is Logan, co-owner of Blackjack Bullets. Just wanted to poke my head in here and answer questions and provide transparent answers for you guys.

No there aren't any factory 25 cal rifles with 1:7-1:8 twist barrels to shoot the 131 ACE's. We know that and our target market isn't the hunter that has a 257 WBY that shoots 7 rounds a year at a paper plate and 2 at a deer. How long have 105-115g 6mms been popular? Until recently how many factory rifles have fast enough twists to fully stabilize them? The market that the 131's are designed for already shoot custom rifles and wear out a barrel or 2 or 3 a year. Barrels are something they are already going to buy weather its a 1:8 6.5, 1:7 6mm or a 1:7 .257 its no different.

On to the BC: We advertise .330 G7 this is not a made up number from a range day trip. We did testing with a 25-284 with 1:7.75" twist bbl through an Ohler 88 system with 1000y TOF that takes out variables such as scope tracking, mirage, shooter error and environmentals. The reasoning behind this is that @ 2940 fps (a velocity obtainable out of a x47 case) the SG is 1.5. That is just on the edge of "fully stable" which is not optimal for best BC numbers. We wanted it this way, Why? Because we wanted to advertise the actual number from testing in sub optimal conditions so that anyone that spends their hard earned money on our product is pleasantly surprised when they see results better than advertised, completely opposite of the industry norm. There are some very reputable shooters out there with our bullets (bought on their own dime) with 1:7 or 1:7.25" barrels that reports are consistently .340-.350 G7 in real world shooting at distances out to 1800y.

To the comment about the bullets "it would be one of the most picky bullets to dial in" We have only had 2 customers up to this point having concerns with this. One ended up being an issue with using old brass that had been necked up and down multiple times between 6.5 and 6mm, a donut had formed and once that was taken care off accuracy was great. The other has just recently been brought up and we are working with them to figure it out. Mark Gordon did an initial review of them with his version of "seating depth first" load development. He tested from .000 to .095" off and determined that they shot best at .035" off but had good accuracy throughout the test.

We understand the skepticism and actually welcome it, we are not trying to bring in customers to buy once and be disappointed with results and never come back. We want to bring the best product that we possibly can to a currently neglected segment of the market and have customers that can't get enough of the advantages that it brings to the table.
