Yep to the second question. But in a savage I think the Lrp is enough mill to bash. and allot cheaper than both. Different class mill all together. The other two belong in a question with the Nova rossi and picco. Not the LRP...
You can't put the JPX or OS .28 in a savage either, they are both bump starts only. LRP or Picco P3 (with pull start) are your best bet and the picco will out run and out last the LRP for a few bucks more.
