Good afternoon gents,
I wasn't too sure where to post this, so I hope this is the appropriate section. My employer is looking at potential ammo loading vendors for a project we're working on and I'm trying to get some data related to it.
We're looking at the Remington 150 gr Core Lokt 308 load for our intended use. In its factory loaded configuration, it'll push 2,600 - 2,650 FPS from a 16" barrel.
I've seen chrono numbers from guys running Hornady Superformance 150 gr 308 loads pushing 2,900 FPS from 16" guns. I've also seen a post on here by a board member indicating chrono numbers of 2,493 FPS with 165 gr Superformance loads from a 12.5" barrel. Some limited independent testing on our part has produced similar findings.
We're tossing around the idea of sending some factory 150 gr Superformance ammo to a custom loading vendor, having them pull the factory projectiles and properly seat new 150gr Core Lokts in their place. I'd rather not dive into the "why" part of this on an open forum, so please feel free to PM me if you need further details.
So after the somewhat long winded introduction, my question for anyone here who may know or have a source for good data on the subject, <span style="font-style: italic"><span style="font-weight: bold">if we're able to drive a 150gr Core Lokt at 2,600 FPS from a 13" barrel, as this would mimic its velocity from a 16" barrel, can we expect the same performance (both terminal ballistics and external ballistics)?</span></span> Obviously, in house testing with chronographs and ballistic gelatin will be done to confirm this, but I'd like to get an idea as to what we can expect prior to committing to this project.
Assuming all other variables such as rifle, barrel twite rate, temperature, etc...were the same, I'd like to know if there's anything else we should be taking into consideration.
I see there were some previous issues with the Superformance loads related to popped primers and overgassing. I should note we haven't had any problems with reliable functioning from the gas guns we've tested thus far.
If anyone can offer some insight on the subject or provide a source for info, I'd very much appreciate the help. Thanks for your time guys.
Regards,
Tspeis
