I picked up a box of Gevelot .338, 265 gr RN bullets around 1980 when I had a .338-'06. I loaded them to 2480 ft/sec and tested them in a recovery box filled with moist fresh sawdust & silt. This mix is 'softer' than that recommended by Bob Hagel, which uses rotted sawdust, but the relative values are comparable. The 250 gr Nosler Sp, tested in the same medium, penetrated 7"-8" more at all distances. Penetration of the Gevelot was 30" at muzzle, 34" at 100 yds, 34" at 200 yds and 35" at 340 yds. The bullets performed very well, retaining 55%-60% of initial weight. They appear to have two core densities, the front section is quite soft, expands well and is easily shed, while the rear section is very hard and does not expand at all. Cavity diameter was very similar to that of the Nosler 250 Sp. Other than having a low BC and needing to be seated rather deep in the case, I found no flaws with this bullet.
