5 MIL (the fine gradations of the reticle) until 200 yards, when it becomes slightly more. With a 100-yard zero, 40 yards required a +2.5 MIL hold, 100 yards is of course zero, and every 10 yards beyond that is almost exactly. Marty recommended the IOR Valdada 6x scope with the MP-8 "rainbow" reticle, pictured here. 750 BC of the 300-gr.338 bullet, subsonic, makes this round VERY accurate, but it also drops like a rock. Other powders would allow more velocity while still remaining subsonic, but I chose N110 for quietness. My SMK load with 10 grains of N110 is getting 980 fps with and without the suppressor out of a 10.5" barrel. rounds that I am assured DO expand with authority on impact. SMKs with an order into Hawk Precision for some of their thin-jacketed 300-gr. Something has to be last.Īmmo: Marty recommended several powders including W296, and later said that some customers had been using VV N110 to produce "scary quiet" results, so I went that route. Ironically, it was not the Form 4 for the can, the Form 1 for the SBR, the upper, or the dies that I was finally waiting on, but the TROS 3-lug adapter.oh well. So, might want to check both CH and Hornady - I simply cannot imagine the agony of going through everything it would take to build this fine gun and be waiting on DIES. That may have been 2 months ago, and I honestly can't remember if I cancelled my order with them or not after Marty send the necessary materials to Hornady to make me a set in less time than it would take CH. 338 Spectre wasn't on their list to do a run, and it would be 5 months before a run was done since it's a specialty caliber. Marty has had good luck with the much cheaper C-Products 6.8 mags.ĭies: I HIGHLY RECOMMEND that you order dies FIRST - when I called CH.
To clarify, the caliber takes 6.8 mags and 6.8 bolt face. The other piece of equipment you would need is a shellholder to hold the brass as already mentioned. I reload Spectre on a turret press but a single stage would be just as good. This is easily accomplished by using the resizing die. 338 Spectre case is made from 10MM Mag brass necked down to. I did ask Marty to include an adjustable gas block so I can shut off the gas if I wanted to this said, I did not notice an appreciable difference in sound between gas on and gas off however, I have not yet heard the gun shot with and without gas as a bystander, only as the shooter, and racket from the buffer tube and a host of other things make it hard to judge.īrass: As others have confirmed, the.
338 SPECTRE TRIM LENGTH FULL
338 Spectre is the cat's arse is that it's subsonic, ballistically potent (approximately 10mm ballistics with WAY more accuracy and BC), and functions out of a semi or full auto. bolt: I recommend an AR with no hesitation.
