I always set up enough targets, maybe different for each gun. You can shoot .17 hmr's for a long time before you get any real heat going. Especially with a bull barrel.
What's your technique ?
Exactly what I do with my Savage 110 in .223 and .17HMR. I`ll shoot a 3 or 5 shot group with my .223 then put it to rest in the rack for a good 10 minutes or so and switch out to my 17 which has a bull barrel. I`m probably overdoing it with the .223 as far as resting time is concerned, but I`ve read enough about heat to know it`s not a barrel`s friend.
