Thread: 375 Lunatic

HH,
Na, nothing special with the gain twist. They sure tear up conventional jacketed bullets though! We fired a 350gn SMK down it and it took half a day to get the copper out of it afterwards! It doesn't foul at all with the monolithics. We have used a few Bartlein gain twists in 7mm before, but they were less than 1 inch of gain from one end to the other. These radical gain twists are s'posedly for the monolithics, but I'm not sure they're really required even for them. Will need more testing to establish that. Can't fault the accuracy produced with this amount of gain twist so far anyway.

SakoKid,
No, it sure as hell ain't practical as an all round hunting rifle if that is what you mean. But is it fun - hell yes!

LR,
Yep, you're pretty much on the money. Comparing directly yesterday's results with the list BC for the 300gn Berger at 3250fps in our 338 Lunatic, the wind advantage doesn't start till beyond 2000 yards. If you use Terry's .91 BC which converts to .455 G7, then the crossover is beyond 1500 yards. We actually get more than .418 G7 out of our 338 Lunatics, but until we've done more testing with the 375, I wouldn't want to split hairs more than this.
There's a 35% theoretical gain in barrel life, but that is pretty much offset by the extra cost of the monolithics, at this stage anyway. And there's a larger frontal area and more energy, but that has little to do with terminal performance. That comes down more to projectile construction, but we'll see how that goes with some beyond 1000 yard terminal performance testing shortly.
Swings and roundabouts as you say, but I'm sure you're going to have some fun playing with it no matter!
