Hi M1 and Flatland
Here's a summary of parts/considerations/responses:
- Have done the 700 clone way (Krieger 7 twist, long throat, spendy) and the Tikka way (8 twist, factory chamber length) - both are excellent, Tikka costs a lot less
- Tikka started as a Compact for $659, then able to net $140 after selling the stock
- Cut the barrel from 20 to 17 inches, thread 5/8x24 w/shoulder (ADCO in Ohio)
- Chassis is LSS Gen 3 w/interface for carbine tube
- Adds are thumb shelf, MDT M-lok poly bipod (great for this set up!), MDT grip
- Cerakote air cure paint on metal
- Buttstock is Magpul CTR because it locks secure (no wiggle or rattle) and can add comb risers
- 11" LOP is very short - in my head might say that if a kid is less than 11" LOP, then too young/little to be shooting a centerfire
- Sportsmatch medium rings
- 6X super sniper is best of eye box/reticle/FOV + any brain adapts very easily, eliminates zoom in/out variable
- No bedding needed so chassis and barreled action are all interchangeable
- Total weight of set up is #8 - kids will shoot #8 better and more confident/less fear aversion than #6 while able to carry
Note that this all just something I arrived at after years of shooting with my kids/friends' kids. Going the Tikka factory route is a bit smarter. Only thing I'd change would be in favor of Tikka stainless barrel (if were offered).
Hope this helps!
