I am doing research for a young shooter on Savage 223 caliber rifle. The use would be primarily for ground squirrel ( squeakers we call in our part of the country) shooting. The price range he can afford is in the lower priced Savage models and likes the thumbhole 11BTH and was looking at the model 25 as well. I noticed that the 25 has a different style action ( looks sort of like the old Rem 788 type from the outside ) than the 11 or 12. Any experience with one vs. the other.The 11BTH has a lighter barrel than a 12 and was wanting to know of heat issues from shooting multiple shots in succession (not rapid fire). Any other advise would be greatly appreciated. Also can you order a slower twist rate in the Savage rifles than the 1-9 they list.Thank you. Dan
