My 9.3x74R digests 250 TSX and regulates beautifully with these. The Merkel factory target that came with the rifle shows a single hole 2 barrel grouping but no matter how hard I tried, I couldn’t duplicate the regulation of the factory load of 286 grain bullets, but I did find redemption using the 250 grain Barnes bullets.

A byproduct of me loading the lighter bullets to achieve excellent regulation was higher velocity. My goal was not velocity and I was squarely focused on achieving regulation.

I don’t believe that a small variance in velocity either up or down will make a huge difference in game getter effectiveness of a given cartridge for a given game species. Shot placement and sufficient bullet weight and construction for good penetration and reasonable bullet expansion are key factors in my view. With double rifles, I believe achieving regulation is the first order of business, and hopefully one can do this with bullets suited for the game intended using a load that falls within the required performance envelope.
