May not have been the best way to approach hand loading, but I shopped for bullets purely on the BC spec, always looking for the highest BC for weight. I'm not a hunter so terminal was not part of the equation, but the BC on those Sierra 77gr TMK (which I think is a hunting round) is pretty good It's .403 G1 If I recall correctly.
My notes said I used 2.260” OAL but I didn’t write anything about seating to the ogive. I don’t remember that being the case
IIRC the 77 SMK is made for AR mag length and 77 TMK is very similar. That ogive is what it makes it specifically not a VLD, where Hornady’s 77 is.
Kraken trades a dozen more than Coinbase and there's a couple on Coinbase that aren't on Kraken.
I was specifically looking at Dogecoins because they're super cheap and I can just stuff them and forget about it. I attempted to trade in BTC about 5 years ago and my bank cancelled the transactions. I would have been in BTC at around 1k each. Not a big position, like .2btc but that $200 would have been about 10k now! At .04 per Doge, 1000 coins can bake for as long as they need.
Kraken is also cheaper to trade.
It'd be cheaper to transfer some BTC to Kraken, trade it, transfer it back.
Internal ballistics and external ballistics at the muzzle shouldn't change much. It's the external ballistics downrange that will change with the ballistic coefficient, and of course terminal performance will, but that's really just a concern for hunting rounds.
