I recently obtained a new permission and sent a letter off to my licensing dept. to get the land cleared for 22 rimfire and 22 centrefire (hornet). They sent me a letter back saying the land is "suitable for all calibres up to and including .17hmr", with no mention of the 22rimmy or hornet. I was a little uneasy about this so gave them a call and the person answering the phone said he would check and if he DIDNT get back to me within the hour then i was ok to use both. I agreed and hung up. He never got back to me so i was quite pleased but, thinking about it now , still a little uneasy about not having it in writing. I DID take the persons name and time/date of call down. Do u think i should insist on getting it in writing or am i being a little cautious?
