This LM-105 bullet for in .338 claims to have a BC of 1.113:

Seems like the .338 Lapua Mag may become the new king of long range for anti-personnel. .50 BMG would still be useful for anti-materiel, but overkill in weight, etc. for sniping use. May render .408 cheytac superfluous too.

The bullet is about 293 grains, and can get an MV up to 3,005 fps from .338 Lapua Mag, quite a bit more than the .50 BMG.

Thoughts?
 
The fallacy of these types of arguments is that they compare a new bullet of one "technology" (eg, monolithic solid) to bullets of an older "technology" (eg, JHP/OTM) in order to "prove" one cartridge is better than another cartridge. It's also not quite a fair comparison because the "new technology" bullets generally cost 3-4x as much as the old technology bullets.

The argument for .408 was based largely on its use of the monolithic solid, compared to conventional bullets at that time.

Well guess what, if you build a 416 or 50BMG bullet using similar design principles and the same manufacturing technology and get a bullet with similarly high BC, the performance difference will again come down to if the case has the capacity to drive the "right weight" (for the best BC) at a good clip.

Also note that the pressure-tested loads (done by Nammo Lapua) came in around 2750 fps from a factory TRG42 barrel - which is right around what guys shooting the 300gr SMK from 26-27" barrels get. The approx 3000 fps loads had no pressure testing done and were from a 35" barrel. Again, not an apples to apples comparison with regular 338LM loads or typical 50BMG sniper rifles (the AI-AW50 is 27").

That said, if I had a case of these bullets and a barrel of the right twist for my AI 338LM, I wouldn't let them collect dust on the shelf.

new? zak's letter published on his page is from '05.

also, i was really interested in gain twist barrels a few years ago, but i heard the same bad experiences from every gunsmith i talked to. they just don't seem to be as accurate.

his page is sort of difficult to read. (it suffers from a deplorable excess of capitalization.) i can't tell what he's saying, but it seems like he's saying the rounds are shorter, but you can't load them to magazine length?
 
The .50 BMG was never intended, and is not used for anti personnel purposes, except in special and or extreme cases. Other than in the days when Hathcock was playing with a single shot browning with the idea of possibly using the round for sniper duty, the military has not regularly pointed the business end of a Barrett at a human. 10 standing in a line possibly, but not one.....:what:

Carlos Hathcock used an M2 .50BMG with a scope mounted to make some long distance kills. He did take advantage of the slower cyclic rate of the M2 to only let loose 1 shot at a time. Other snipers of the time also made use of the scoped M2.
 
The Ma Deuce has a selector so you can put it on single or full. I can't remember the proper name, but there's a switch next to the thumb trigger that you have to hold down for full. There's a wheel you can rotate into position to hold said switch down, otherwise, it'll be single.
