Agree about fireforming.
One of the reason we do improved besides looks is adding capacity.
With my 30" barrel even with slow rl33 to chase velocity i was not even close to above shoulder nor compressing powder before getting 3100 or pressure sign and this is with 230s hybrids .. With the next build will be 24" means most likely ill be using faster powder less volume inside the case.. Specially with lighter 212 grainer ir lighter. So capacity wont be the issue...i think any powder slower than h1000 needs at least 26" or longer to burn all powder.. So i think the standard is ok if whatever i said making sense...?? Do you agree?
