.308 ttsx 168 gr. 42 gr. H4895 2700fps. 3/4" group. Good enough.
Sharpie dot was point of aim for load development. The 180's were factory stuff with same point of aim.

What cartridge, 06, 308, or other 30 cal

presumed we were talking 308 winchester. I've got 2 of them. I shoot 180 sierras out of my 30-06

I notice that Mustangs is using a powder that probably few have tried. Nosler data shows good numbers with Ramshot Biggame another powder not mentioned above. Their data is with a 24 inch barrel so that would need to be taken into account but would imply that 2900 with a 165 would not be out of reach in some rifles certainly with a 22 inch barrel.

Of course, there are other considerations than top speed when choosing a load.
I am currently putting together a 22 inch 308 so I am going to try some different powders and see what happens but if I end up around 2800 with an accurate load, I will be OK with that. In reality, I have a cheap chronograph so I will probably never know for sure, and it will not actually matter.

I got me some Big Game powder and tried it in my 22 inch .308 and got 2820 fps with 52.5 grains and a 165 SGK. There were no signs of pressure, but it is a compressed load to the point I couldn't get more powder in the case. I haven't shot it for accuracy but obviously 2900 fps is not possible with my rifle.
