First off - congratulations on surviving!
I had my chest cracked and triple by-pass on February 18 (following a heart attack and a stint on Dec31).
My surgeon said wait 3 months before doing any shooting. My Cardiologist got me enrolled in an extensive PT/exercise program at about 10 weeks. This part is really important, IMO. This went on for 3 months.
I started shooting the 6.5 CM, 308 & 22 on June 7 - so I gave it almost 4 months and started with the light stuff. Was doing dry-fire practice well before however, (as soon as I was OKed to lift 10+ pounds).
Started back with the 9.3x62 (my largest bore) on 8/1/22. 8 rounds of 250s from the sticks - I was a little sore in the chest that night. Next outing - with the 9.3, was 10 days later with no issues.
I've been running 300 gr A-Frames (plus some 286s) since 9/1/22 and feeling really good.
I'm shooting two days per week and hiking 2.5 to 3 miles the other 5. Health and state of mind continues to improve, btw.
I'm headed back to Africa June 2023 (Lord willing), and will turn 74 while I'm there.
So my advice is use your own best judgement, but don't be in any rush with that 470.
BTW, the pic below shows what I was working on this morning (at 50, 75 and 20 Yards).
It's good to be alive...
