We were discussing this bullet on another forum and Logan co-owner of blackjack bullets chimed in. Here is his post from that site

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.
