Trophy bonded Bear claws by federal are in 270, 280, 3006, 7mm mag, 7WSM and 300 WSM. (all $42-45 a box). save the brass, you will learn to reload!)
Sounds like 280 or 7mm mag would be OK or even the 7WSM if you want to stay with that Browning action. However, I am a fan of the 300WSM personally.
I would build what I wanted and be done with it one time and forever happy.
Good custom action with lug will cost $850-900 (stiller, Tooley, etc). Money ahead and you will never regret. That is the only way to go versus reworking a factory action.
Here are pics and info on the Tooley Tooley Orion action pics as requested.
I am picking up this weekend my 6.5x47 with a Tooley action ($850) and Stockys LR Bobby Hart stock ($300)
FYI my smith was very impressed with the Stockys laminated stock that was inletted, recoil pad, and clear coated already for $200. That is very hard price to beat. I would not bother ordering it with pillars. They will never match your action and have to be redone anyway when bedding.
Stock (Manners, Russo, Stocky) $200- unlimited
Barrel 24-26" in #4-5 contour
Weight 7.5 to 9 lbs finished depending on stock. Your scope will be another 1 lb plus.
Here is my version. No Click LR carry gun
there are several drop in stocks that will work depending on what you want (glass, wood etc) and all they require is bedding. Joel Russo can make one similar to mine or almost any style and type wood.
As to the firearms insurance, that depends on the state you are in. All state policy parameters are set by the state insurance commissioner and mandate the minimum levels of coverage for items such as firearms in that state. I have seen firearms down as little as $200. For perspective, $2500 is the highest I have ever seen. A rider can be purchased to cover full coverage for about $10 per $1000 needed.
