Mike,

Interesting the Unique load posted above is one of my favorites, as is using the .339"-250g LFNGC over 17.0g Blue Dot, again around 1500 fps depending upon barrel length.  Too, 20.0g 2400 is a great load for these reduced velocity purposes in the .338 Win Mag.  Just make sure the bullets slightly engage the lands in the throat when a round is chambered, and they'll shoot very, very well!

I've popped Oregon Blacktail deer with these loads in the orchards doing some agricultural depredation work in days gone by, and they were quite effective when the noses were annealled.

Enjoy, and God Bless,

Yes,

In a Ruger KM77MKII, that I had specifically throated for the long forward driving band of the .339"-250g LFNGC bullet, so that the base of the bullet and gas check were flush with the bottom of the neck in the brass when loaded.

Once the throat was lengthened to accomodate this bullet, it would shoot sub MOA groups on demand using 74.0g IMR4831/WLRP/Win Brass.

A real sledgehammer on game out to 300+ yards!

The gun never did shoot this bullet well until the throat was altered however, as the bullet was seated too deeply into the case in order to chamber, and the bottom lube groove was exposed to the powder/hot expanding gasses on ignition.

This bullet also shot relatively well in a Sako Handi-Hunter model that was manufactured for a limited time, having an 18 1/2" barrel.  The throat in this gun was long enough for the bullet as it came from the factory.  Although not as predictable as the re-throated Ruger, it would still shoot into about 1 5/8" at 100 yards with monotonous regularity using the .339"-250g LFNGC.

Hope this helps!

God Bless,

Marshall
