The 195 is a fantastic performing bullet in the .284, and that cartridge won’t blow them up when the barrel is hot like an rsaum can do. Thin jacket and easy on brass heads to accelerate.
@Ned Ludd had written last year on a query of mine about how there can be deviation in the correlation between drop and BC and drift.
I’m still a little unclear but I revert to a mind picture to straighten it out. I think Lapua is in the land of exception where it drifts expectedly but drops less relative to its peers.
If I have it about right, 100 yard wind drift is 1/100 the amount of 1,000 yard drift. Doubling the distance to a target is 4 times the drift. Tripling the distance is 9 times the drift, etc. 1,000 yards is 10 times the distance of 100 yards and so bullet drift goes from say 1/3 an inch, to 33 inches - 100 times more. Whereas gravity pulls all objects downward at the same rate, but how fast forward motion slows down, is what is different between bullet’s BC.
So a bullet - mental image - that can resist being turned by wind such as a very high BC 16 inch naval cannon round will start at perhaps the identical velocity of a 300 win mag but drift relatively immeasurably in the first 1,000 yards, due to wind. It’ll retain velocity better and if both are fired to maximum range go six times further.
Just my opinion that the Lapua scenar drifts commensurate with stated BC relative to Berger, but the bullet somehow defies expected dropping. It’s made me wonder if its design essentially cheats the most rapid deceleration/turbulent stage bullets go through skipping straight(er) to perfectly stable, “asleep” flight, something that would subtly escape the hard prongs of rote bullet BC and velocity data, and net higher impacts. I’m just glad my high impact observation/opinion wasn’t spurious.
Whatever it is, it wasn’t an accident. Lapua has always had big heads in the game.
