The last 545 ammo I bought was back in 2019 & it was RAS by Vymple for $199.00 plus shipping, everything before that was GT by Vymple for $179.00 plus shipping as it always shot well. There was a couple of cases of 545 made in Ukraine that was corrosive & came in 1400 count crates, but it was advertised as non corrosive & ticked off a bunch of buyers.
It's too expensive to buy now, so I don't. There are more than a few crates or 7n6, but that came from Knob Creek years ago & is being saved for a rainy day!
