ULTIMATE - SHORT BARREL CARTRIDGE???

[ja4wheel6]

Hey,

Looking to build a short barreled long range gun. Wanting 2925 fps with 180 eldm but sub 20" barrel. Open to other options outside 7mm.

Options so far, 28 sherman mag, 28 nosler, 7-300prc.

Any ideas?

Not trying to convince you, but another data point.

25-7prc (West Texas Ordinance reamer)
133 berger EH
ADG brass and N570
~3060 @ 18"

7 NMI will do it, I've got one.

Why the desire for such a huge bullet with a lot of recoil?

Where does shootability factor into your concept of 'ultimate'?

I put together a tikka t3x in 7 Backcountry last weekend. 17.5" barrel was shooting the 170 terminal ascent at 2940 fps, the 155 terminal ascent was at 3040, and the 168 lrx was at 2890. With the suppressor will have total barrel length around 22.1". It shot the 170 best which is what I hoped. At 2940fps and .646 bc that will be way more effective than I am capable of as a shooter. Take a loot at that route.
