Once you get all that then you realize that the wait was well worth it.

You have to wait for the barrel unless SBR has some in stock, you have to wait for the dies to be made (CH-4D is the only source I know of and they were running 6 months on custom orders the last I heard), and you have to wait for the next run of 10mm MAGNUM brass to form. The deal with the Spectre is you must be prepared to wait. That's good to hear about brass life, maybe I won't have to worry about that aspect since I would only shoot subby's. There is not a tremendous amount of load data out there, but if you get a Spectre, let me know and I'll give you what I have. I got a YHM 338 suppressor (primarily for a Lapua) and it does a great job of suppressing with less than an inch change of impact from the unsuppressed barrels. I was not 100% pleased with my YHM Cobra 9mm can's performance on either the SBR or the 16' because it did not seem to get the subsonic rounds quiet enough and gave me varying POI shifts. They are fantastic on wild pigs, especially suppressed at night in a populated area.

I have never had brass crack on me.īoth rifles are capable of sub MOA, though I primarily use them for under 100 yards. Brass –– especially suppressed –– lasts forever –– I have some going on 20 reloads. The Sprectre uses the 10mm mag brass fromed via a single run through the sizer die. I got one barrel from Marty at Teppo and another through Marty. I have a couple of 338's, one an SBR and one a 16'. My personal preference 'spectre'.I've got some printed info I'll look up.

If so, another plus for it.Īnyone have any experience with either or can direct me somewhere that user info can be found? I've been to the SOCOM forum, but there's not much there on the Spectre. I believe 338 Whisper brass can be formed from 223 brass. One reason I'm interested in the 338's is the ability to use a 9mm suppressor which I'd like to buy for my USP9 anyway. From what I understand, getting uppers for the Spectre or 458 SOCOM, another candidate, is next to impossible right now. I've read the FAQ on the Spectre, but can't find much user experience on it and even less on the Whisper. The 300BLK is on the short list, but I'd like something that shoots larger and heavier bullets since the energy numbers for subs is not that great. Let me know if you all have any questions.I'm interested in building a suppressed AR that will likely only shoot subs. That seems to have taken care of the problem. I polished the lugs and the bearing surface on the bolt because it had a very rough finish. The gun would go 'click', and there was no dent in the primer. I also had a problem with the bolt not fully rotating into position when the bolt carrier was fully closed. The added spring pressure of the new kit also made it harder to get the extractor over the case rim, so I had to polish the extractor nose.

The extractor spring was not strong enough to pull the round from the chamber, so I had to add the extractor spring upgrade kit. I've had some issues with the 6.8spc bolt I got from DPMS. The load data I have for that, shows the 200gr bullet going 1550 fps with 18gr of 4227. I have recently picked up some 200gr Hornady V-Max bullets for working up a super-sonic hunting load, but have not gotten to loading any yet. With 12 grains of IMR4227 in the 16' barrel and the suppressor attached, I get 1075 fps with the gas system shut off (scary quiet!), and 1025 fps with the gas system in the 'suppressed' position with the action cycling. The Lapua bullet was a little more accurate, and was averaging just over 1 MOA at 100 yards. I'm currently using a 2.26' OAL for both rounds. The Lapua bullet will seat further towards the rifling if they are loaded with the same OAL. I'm using 12 grains of IMR 4227 behind either the 300gr Sierra Matchking or the 300gr Lapua bullets.
