1. 30-30 is not a common chambering.
2. The tang site is worth $100.
3. W/O knowing the model pricing is difficult.
4. If you are gonna mess with 99s AT ALL you must buy David Royal's book:

5. Any 99 with a really fine bore (you must bore scope it) that is all there with no lousy refinishing job or wood issues is a $500 item.
6. Get some pics and post them pls.
As for the 303 Savage, it's a fine round. Norma & Privi make brass (https://www.midwayusa.com/product/10...age-bag-of-100) and
with spitzer bullets it exceeds the 30-30's performance.
There is a member on the 24hourcampfire.com named "Lightfoot" who makes a wonderful no drill mount for 99s allowing the use of modern scopes. I have one on my solid frame 22 HP ---- its great !
