Thread: Information on cutting barrel length on a 7mm rem mag

Been thinking for a while about this "super pig" concept and have a few questions around it

My barrel is fluted can I cut into the fluting or is that a no no?

I'm Running Hornady superformance ammunition for reference
What realistically is the shortest I can chop the barrel without affecting shot placement and muzzle flash?

Not planning on shooting further than 500m at the range and 400m max on the hill.

any input would be much appreciated!
