--Finally decided to take the 38-55 leap for a new hunting rifle. Just bought a Win. 94AE That I want to have JES convert but I am not sure how many grooves I should ask for. I've read a lot of posts, but they usually speak of smaller bores, especially 6mm. Any of you have a Like/Dislike for this round? Many posts say it does not matter only that fewer are easier to clean. So do any of you have any of you have any knowledge on this that you would like to share?
