Problems w/ .338 Ultra and seating press??
Does anyone else have problems w/ the loaded .338 Ultra round (3.600") being too long for the bullet seating press? I find that I have to twist and yank to get the suckers out of there...is there an easier way? Do they make Seating presses that are bigger/taller/longer?

I use a rockchucker press for my 300 RUM.O.A.L for mine in 3.725.I turned my shell holder so I have to load it from the left side.I don't have any problem's with mine...

I've had the same problem reloading for my .300 Ultramag. My problem isn't with the press-the shell holder is tight enough that you can't tip the shells when removing them from the press. I chamfered the edges where it contacts the groove in the shell and it helped. I also use a rockchucker press.

The RCBS Junior, Reloader Special, and some other presses just don't have enough throat length to take H & H -length cartridges, without using some tricks.

Try backing your seating die off to give you more clearance. You can get possibly an eighth to three-sixteenths of an inch this way -- just screw down your seating stem to compensate.

Throat clearance is the reason I switched from an RCBS to a Lyman Orange Crusher for full length magnums.

Never had any problem with my Rock Chucker seating anything shorter than .50 BMG. And for those times when I do want something REALLY long, I use the RCBS Big Max...

Even the LEE "Challenger" has no problem with the 338 RUM, or 460WBY lenght cartridges.
