OAL is always gun & bullet specific. You are just loading too long for that bullet in that gun. The fat ogive of the 1R makes seating deeper required. Nothing wrong with the 1R, just try it shorter, like 1.240". No such thing as seating too deep if it functions.
EVERY GOOD SHOOTER NEEDS TO BE A HANDLOADER.

Even in my 1911 barrels that have some throat I cannot seat the 228-1R longer than 1.220."
