It will be interesting to see how this works out... I can already get good accuracy and 2625-2650fps with a 140eldm in my 16 inch tikka 6.5cm with rl16 or n555... and by my math, a 153tmk at 2900 in a 24 inch barrel will equal about 2660fps with 30fps loss per inch of barrel length... so a bit of an edge, and it might be nice to have factory loadings that do what only handloads do now...
But, as has been pointed out, I would expect more recoil and worse barrel life...
However, there are new braked suppressors on the market like the TENET limited that might be the answer to the recoil issue... and there is new-ish barrel tech from Proof and Seekins with the exponential twist (or gain twist) barrels that might solve the barrel life issues...
Exciting times to see where all this new tech takes us.
