I have an HTI. You can change calibers but the mags for .375 are funky... Like SKS mags with the long lip. Stupid. In BMG though it's not like that. Uh, what can I say? It's a big motherfucker that holds a big ass barrel and gets it done.
If I had it to do over though, I think I'd get the Harris .50. I just like it. Is it better? I don't know. I think it's the one the SEALs used to kill the shitbags on that freighter. I wanna say it's a no-shit subMOA rifle. The HTI is advertised at a .5 MOA rifle but I've never tested it like that --it's kinda hard to find a good place to take it sometimes. But you haven't blown red dye water milk jugs until you do it with a BMG. They disintegrate in a puff about 20' in diameter! API is the titties and Raufoss, my god. IF you get your hands on those, save 'em. They're legal for you to own but someone somewhere broke a law to get 'em to you. For a bolt gun though, I wouldn't be firing API/T or ball. Brass solids only. Those barrels go to shit after what, 1000, 2000 rounds? I forget. But it's not much. I guess that's why they make such nice barrel gauges for M2HB's.
$6700 for a repeater rifle in this class from a quality mfg., do it. That's giveaway prices. Just do it, don't look back. IF you still wanna get into .50.
Legacy costs for it are the biggest issue, not the rifle. Ammo is NOT cheap. If you load, the components are way more expensive too. I buy my shit in bulk from govt. auctions, 10,000 pieces at a time. Only way to go. And you WILL wear out a BFR press and test Dillon's CS (which is phenomenal). Also, and here's a tip for all you reloaders regardless of caliber but ESPECIALLY the big ones --lanolin lube. Either Imperial wax or the spray shit I used to sell before covid killed my alcohol supply (basically emulsified pure lanolin and 99% ispropanol at an 8:1 ratio). Harder to clean off but man, makes all the difference with sizing.
Uh, don't use CH4D for your supplies, they're cheap for a reason. God forbid you have any problems with them because it WILL be your fault, not theirs. Even if they JB weld the goddamn stem to the body, that'll be your fault and they will go to the mat over a refund --in the end CC company took the hit because I wasn't willing to bend. So who do you use? If M2 still makes dies, then him. He's the best. But he told me he was folding up shop some years back, then I saw he was offering 'em again a few years later on a limited basis. They ain't cheap, wish I had a set. They'll be custom made for your chamber, so not necessary if you get a semi. Whidden is my goto for custom die shit --make sure to speak directly to the die shop manager, he'll take care of you.
I'd post pics but apparently all my files are too big now after the update.
I just got an MRAD though and I think that one will get used a lot more. And I'll probably take advantage of the ability to swap barrels in this one. MRAD is a bad motherfucker and I totally see why it was the Remington killer for the military. Not a BMG but considering military is going to .338LM or Norma over BMG for everything EXCEPT static anti-material roles, well, it's worth thinking about.
I don't know if this will help your decision or not, but I'd consider selling the DTA HTI because I have an MRAD. The M2HB? Fuck no. I wanna be buried with it, just in case. Easily one of the most fun weapons available. They only go up in cost too. Mine was NIB at $8k --good luck finding a used one for that. But then you got tripods, mounts, lights and lasers if you wanna go the mounted night route, oh and don't forget the $6k for roof mount shit. Or $4k if you wanna make it into a high speed technical. You can always weld a pintle to the frame and go the haji route though.
I named it after my ex-wife --it's a loud, fat, mean heavy bitch... Nothing beats that "BOOM, BOOM, BOOM!!! --boom, boom,boom!"
Oh, for suppressors? I guess Barrett if you get a Barrett. And I saw one once made for an M2HB but he was just experimenting. But Elite Iron for any bolt gun, hands down. Dale does NOT fuck around. He's fitting my MRAD with a Sierra SD right now. He always goes the extra step, indexing the can TDC. Built like a tank. He makes the brakes for all the Harris rifles too, so he can supply that and the can both indexed so no need for shims if you wanna swap (because you gotta have something on there, fact). The wrench flats were a plus.
If you wanna make us all look like pussies though, there's a mfg. here in WA somewhere that makes a 20mm Vulcan rifle. It's 6' long and weighs over 100lbs. I saw a guy loading for one once and he modified a log splitter for a press. I think Sirhr does something similar for one of his cannons? So the rabbit hole does go much deeper...
