I need some advice on the use of one moderator on two rifles.
I have a 6.5 x 55 and a 7 mm Rem Mag on my ticket. I have permission for a moderator for both (two separate entries on my ticket). I have bought a 6.5 x 55 rifle and hope to buy a 7mm in due course. As yet I don't have a mod for either. The 6.5 x 55 came factory screw cut. It is a bog standard Sako 85 stainless synthetic. The thread is 14 mm (according to the bloke in the shop).
I ordered a mod today from my local shop. I went for a stainless ASE Northstar. I ordered the .30" version with a 14 mm thread.
My understanding is that 6.5 mm is .264 in imperial and 7mm is .28ish. If this is correct, and subject to the nuances of my FAC (which I won't go into here) and the 7mm having the right thread, it seems that I could swap the mod between the two.
My question is - are there any problems associated with using one mod for two rifles. I wonder if this is good / bad practice and whether it can lead to flyers or other problems with accuracy. The mod was quite expensive and if there are no down sides from swapping it between the two rifles I could save myself some cash by doing so. If there are problems I will get a separate mod for the 7mm when I get one.
Any advice about swapping would be very gratefully received.
