Here's your difference in bullet length as a function of weight:

You can test your ammo by chambering it and see if any rifling marks appear
on the bullet and see if the overall length of the round is reduced.

That Winchester warning only applies to heavier bullets because the ogive is
blunter and the bullet is longer.


Hosanna!
