338 cal

I have the 338 cal 245gn version and have tested them in my 338 snipetac with excellent results. 100yd groups were one ragged hole. I kept the speed down, 3600fps.

I also have the 375cal, 416cal and 458cal bullets yet to test. I will be testing the 375's in my 375 snipetac and the 416's in my new 416VM big boomer.

As far as brass hard on bores, nope. Its made from 36000 grade half hard stock. ive shot lots of them with no adverse effects, Heck the Hooker tacticals are made from a harder aloy of copper/Nickel and they dont hurt the bores. There is less baring surface as well with the thin grooved driving bands.

200 yards-1737 fps, 1005 ft-lbs

Such a bulelt in a 458 Socom woiuld have military or LEO uses for breaching doors and locks. I've experimented with a 50 Beowulf shooting 36 grain teflon balls at 5000+ fps. They're like little grenades at 25 feet but nearly harmless at100 yards. They're good for targets where heavy slower bullets leave a hole but don't do much damage. On big game at short range it would most likley give surface wounds which might be lethal but not quick kills.

Here are pictures of three of the Lehigh bullets which I also posted on the 458 Socom forum. The problem for most people shooting the low drag solids besides twist rate is trying to fit them in a magazine. Note the 582 grain Lehigh solid in a 458x2 American case. It will just fit in a Rem 700 long action, the same OAL as a 458 Lott or the 7mm STW (shown).

From left to right is a 223 Rem, 458 Socom with 280 gn Lehigh spitzer, a 338/7mmBR with with 245gn 338 Lehigh boattail (subsoinic) , 308 win, 458 Socom with 582 grain 458 Lehigh boattail (subsonic), 458x2 American with the 582 grain boattail (subsoinic) , and a 7mm STW. The "standard" cartridges are for size comparison and are close to SAAMI spec length.

This picture is three of Lehigh's 458 bullets. 280 grain spitzer, 528 grain extreme expansion hollow point, and 582 grain boattail. McDrag calculations for the 582 shows a G1 BC > 1.0 both subsoinic and over 2000 FPS. McGyro gives requried 10" twist subsoinc and 12: at reasonable supersonic velocities. 9" is requried for transsoinic muzzle velocties.

I have no concerns about barrel damage but possibly about fouling. Dave (Lehigh owner) told me one of his customers uses Imperial sizing wax as a bullet lube in the shank grooves for shooting subsonic. Engraving and bore friction forces on large solids is significant.

Re: Two ?'s Lehigh bullets & twist rate

Hello I'm new at this but saw your thread thought I would offer a little info on the Lehigh bullets. I shoot a barrett 99 in 50 bmg with the 795gr. hybrid from lehigh it is awsome. i have had some groups under 1 1/2" at 400 yds. but anyway. Either call or email David he will probably send you some samples he sent me some for my 50 bmg it wont hurt to ask
