I am building my first long action rifle. However my long action barrel (280 AI) will not be delivered for several months.!

Now I know its probably unorthodox, but are there any issues with temporarily installing a short action barrel on a long action receiver? You see, someone is offering me a brand new 6.5 Creedmoor take off barrel and I am considering the purchase for my new build.

The rims are the same in the 280 AI and Creedmoor, and the Creedmoor fits and seems to feed well in the long action magazine...

I realize my bolt will have to make a needlessly long journey to strip off a round... but... aside from that, shouldnt this work just fine for a few months till the right barrel comes in from the manufacturer?

In other words, is this done or am I just the biggest weirdo here???

BY THE WAY, my action is a NUCLEUS Mauser type with controlled feed... Surely that will work in my favor, won't it?

Thank you everyone. Good night!
