I've seen it mentioned sometimes here. Its a typical long range cartridge.

I heard it mentioned in a magazine recently; Im thinking it was an article in G&A about extreme long range shooting. Not sure though. I like the way it sounds. You find any info on it, post it here will ya. Id like to know how fast this thing would shoot a 250 gr Partition.

David-
I don't know what velocities he's getting, but I met a guy who killed an Elk at 2890 yards with it. BTW- he used a Match King for that (300gr).

It's also mentioned in Steve Hanson's "A Varmint Hunter's Oddysey".

Hey guys,
I just got an email from Darrel Cassel who has this cartridge, Boyd Heaton had told me to email him for the info. He has kindly responded.

It is a Rigby case with 0.015" body taper base to shoulder, 35 degree neck and neck length of 0.338". In a 37" barrel is pushes the 300gr Sierra Matchking 3300fps.

This is exactly what I had been thinking of doing to the Weatherby case to try to simulate the .338 Excalibur. There is a fellow who has one of these, I have been corresponding with him and I am waiting for him to send me some velocity data. Either way you cut it gents, these are BIG friggin' guns.

Gents - What is wrong with the .338 Lapua? You have brass, dies, reamers, custom-factory ammo, and hand-loading data already available. There is not 50 fps between a .416-.338 wildcat and the .338 Lapua.

By attempting to increase the case capacity beyond the Lapua, you wind up burning considerably more powder for only a few fps difference. You are truly at the edge of diminishing returns.
