Hornady Modified Case 7.5x55 Swiss

If you have a K31 that you're going to reload for or currently do reload for, the modified case will help a lot. With the tighter throat on the K31, you can't seat your bullet to normal lengths and the modified case paired with the LNL OAL Gauge from Hornady takes the guessing out.

I find the Hornady L-N-L OAL gauge useful for all of my reloading, but it is particularly valuable for the K31. The K31's chamber and throat geometry makes bullet seating depth more demanding of precision. Correctly seated bullets tend to be deeper inside the case neck than with other calibers. The gauge will also show if your reloads will fit the magazine.

While there are other ways to come up with a COAL that works for your rifle, the Hornady OAL gauge fitted with the 7.5x55 case will save time. You get it right the first time.

With supplies of GP11 no longer plentiful, reloading is now even more essential for the K31 shooter. Since the original GP11 bullet is not sold commercially, substitute bullets are needed and getting them seated to the rather tight dimensions of the K31's chamber can be a vexing challenge. The Hornady OAL gauge and modified case eliminate guesswork and trial and error testing.
