I'd suggest some of you actually ask a bullet maker why you don't see a 150+ 25 cal, or better yet go to the Corbin web site and get the gear to build your own bullets.
To get the 160 Matrix was a pile of work over a couple years, just to get a jacket was a battle. You don't just order a special length jacket for kicks and giggles to make a bullet.
There seems to be a lot of whining about the 270 getting high BC bullets, well there would be no 165 if Marshal wasn't into the 270 cal in competition and bought the equipment and do the testing and foundation work to build it. The 170 Berger took Bob Beck and Extreme Outer Limits to get behind it and I suspect swing a heavy financial bat.
Some seem to have the idea that it's no sweat taking a cup and core bullet and just sizing it down a few thou and it'll be all good, it's not easy, the smaller the bore the harder it is cause of how much you increase bearing surface length, so you end up with a heavy for cal bullet with so much bearing surface you have to launch it with a higher capacity case but the twist rate and capacity required make a jacket tearing monster that no one wants. Look at the Berger 195, I know a lot of huge 7mm fans boys who won't run it because the extra bearing surface really put the brakes on in some chamberings.
The 270 makes everyone's top 10 list in popularity and sales and often the 270 Win and WSM are in there. There is not a single quarter bore in any list other than the dodo lists, which is unfortunate but you run a business of sales, if you want to see epic quarter bore bullets generate some sales!!
This thread has a custom bullet maker even asking and offering to build the best he can and you guys turn up your nose and make zero effort, ya that's the way you get traction with manufactures
Then to top it of it's fun to B***h about no bullets then when the offer comes, nope don't want it cause it suxs and we don't shoot them anymore or they burn barrels so wont' shot much, yep that should motivate some bullet makers to roll out some quarter bores!!
Maybe shoot what we have and prove it worth the effort, I have a 25x47 Lapua on the board for a med range thumper running the 130 Matrix, after testing the 130 Matrix out of our 250 AI I think it would be a great 600 and in elk and mule deer rig.
Build a 25 cal benchrest rifle and go kick some butt with it, that will also get you some traction just like the 6mm 105 and 115 which few factory rifles are able to run but their sold by the semi load to comp guys or those of use who will pull a barrel and twist up our hunting rifles.
An even better idea is build your self an epic quarter bore, get thousands of dollars worth of camera equipment, tens of thousands into tag and travel and make an awesome hunting with the quarter bore video series, that may do it also. Bottom line action gets traction with bullet makers not whining on the internet!!!
