Oh just read your other thread stating its a Tikka M55. Probably wont be able to load them to that mag length so just seat them as close to the lands a poss leaving no less than 40-50% bullet to neck contact to keep them nice and concentric.
1-14" seems slow for an old Tikka, does it have "Bofors steel" stamped on the barrel?
The earlier LSA-55 and M595 .243 win was a 1-10" twist so unless your barrel has been replaced Id be willing to bet its a 1-10" too.
