Friend just put a nightforce on his shooter, eyepiece rotates with zoom. Is that normal? Locking ring tight or loose doesn't matter

Started reading about them until a big banner offering 10% off popped up right in the middle of the page with no obvious X to close, and a chat window popped up, so I closed the whole page out and moved on. Told them about it in the chat first though, just a bot judging from the instantaneous long winded response!

Mine expired a few months after the warranty expired. Buttons quit working. Did call the company. 2 pairs of Pro golds both started exhibiting problems, old pair had a 5 year warranty, went a good year after the 5 year warranty expired, then the right channel started screeching, the newer pair went a year after the 1 year warranty expired same issue. The pink Pro Ears I got for the woman still working. Talked to the shop about all 4, obviously I'm a repeat customer and 3 for 4 you would think they would do something to make there customer feel valued, but no, they toed the line on the warranties. Did get a nice "I'm Sorry" out of them, that and $5.00 will get you a cup of coffee at starbucks. I'm looking for a different brand for the next pair. Expensive ear protection should come with more then a 1 year warranty.

Had the 10mm blaster out to the range a few times over the last month, has been 100% reliably chewing through everything from light tightgroup loads to full blow AA#9 loads and brass is coming out in reloadable condition. Shoots the loads I use in my 1911s, the ladder loads I worked up for the carbine, factory 180 Federals, and a good bullet puller for anything that says 10mm laying around on the bench and floor. Adding the weighted spacer in front of the heavy buffer seems to function fine, no issues. Might have even improved the deadblow effect, feels really good when cycling. Scoring the JRC 8-1/2" internal depth carbine extension was the final piece of the puzzle. Guy on a muzzleloader forum pointed me to that, believe it or not.

Great photos. Love the old war birds.

OK, squared away. Opened up the barrel port to 0.110", opened up the gas block to 0.110" Cycles and locks back on everything. 300BO Pistol configuration 9.9gr H110 powder 220gr subsonics 10.5" B/A Barrel 1:7 Pistol gas 5-1/2" +/- dwell Port was 0.095, stepped it up to 0.101 (Stepped it up again to 0.110") Yellow Sprinco 20% reduced spring

I do not have the wherewithal to successfully undertake the gas port system evaluation and R+R . ^^You need to do this^^ Still am trying to wrap my head around the reason why the rifle works great with heavier rounds. ^^To understand this^^ These things are pretty simple. Baby steps, follow through the waterboarding thread. Take pictures and post. Most everyone here started out same way.

Been following this thread, 300BO Pistol configuration 10.5" B/A Barrel 1:7 Pistol gas 5-1/2" +/- dwell Port was 0.095, stepped it up to 0.101 Yellow Sprinco 20% reduced spring Shooting for Subsonic 220gr Off the bench cycles and locks back Lil Gun and H110 220gr handloads and Grizzly factory 220 gr subs Off hand tight to shoulder cycles but iffy on lock back Hold at arms length cycles 2 out of 3. Looking into the port with the bore camera the gas block port is smaller then the barrel port. Seekins low profile AGB. Next step open up the gas port some more. Is opening up the AGB port a thing? How far should I go? With powders like Lil Gun and H110, enough gas pressure for subsonics? Only have 100 rounds through it, maybe more break in?

Signs are up at the Seattle Police Range, no 320's until further notice.

Woo Hoo! 10mm MFer moves from the "Needs Work" category to the MFing Blaster category. Did a couple things, first checked the headspace/ removed barrel, dropped in a round, snapped the BCG over the rim. Ran test adding shims until extractor didn't go under rim, about 0.007". Don't know what it is supposed to be but that seemed good. Full forward BCG contacts barrel face with round in chamber. Go/ No go gauges for the 1911's about the same results. So pushed the finishing reamer in all the way and spun it without pushing very hard, cut the rifling back a bit without pushing the shoulder back much. Used a white wool bit with some jeweler's rouge on the Dremel to really polish the chamber out. Put an 8-1/2" carbine extension on and added another 3.5 oz to the recoil mass. Went with the orange spring. First ran some factory 180 gr. Not too impressive but worked 100% Good SD's. 155gr XTP over 15gr AAC#9 This is what I'm talking about! 15.7 gr AAC#9, compressed load. I think the 2165fps is a mis read by the labradar. 6.8 gr Titegroup 155gr XTP Chewed through everything I threw at it, brass looked great. I'll clean it up and look closer later. Then ran some 300 BO tests. EDIT screwed up the order. Fixed now. Blue 220's, Sierra 220's, and some super-cheapo 220's. 220gr Blue bullets 9.9gr H110 COL 2.130 Lost communication. Edit: I have the order fixed I think. 220gr Blue 2.130 COL 9gr AAC#9 Didn't cycle reliably. 9.0 Lil Gun 2.130 COL 220gr Blues. Budget 220 gr FMJ's 9.9 H110 COL 2.100 #9 failed to cycle at 9.0 gr Lil Gun 9.0 COL 2.100 220 gr budget pill Sierra SMK 220's COL 2.220 #9 at 9 gr failed to cycle. 9.9gr H110 I think the 1152 is a mis read or a bad load. SMK 220 9.0 Lil Gun Like this one. Nice day at the range, got a lot of data. Out of 12 or so loadings, didn't have to dig one shell out. The AAC#9 in the 300 didn't have enough gas to pick up a round but did clear the port with the empties so pretty close. The 10mm ran flawlessly from put puts to full blow loads. Locked back on everything. I see a suppressor in my future.

Here is some brass out of the 40 carbine. Starting to show a little flow. 155gr XTP 5.8gr Titegroup, just about max.

While waiting for a few parts to show up took a look at the used brass. A few of them showed bad signs of separation. Primers don't look bad Especially compared to my 1911 10mm primers.

Good idea on the rifle length extension. I have everything I need to make a stainless rifle buffer in my shop, and a pile of tungsten weights. Probably have a rifle tube as well. full blow 10mm in a carbine is a FUN MFer...

Don't sweat missing this, kind of a back burner project. I get it out every once in a while, run some loads, don't fuk with it for months, run some new ammo or spring, repeat. Yes. Blowback. Getting around 1730 fps w/ 15.6gr AA#9 1640fps w/ 6.8gr Titegroup. I'd scrap it but it's a blast to shoot and accurate, and not very loud. Not much more then the 40. I get around the 1430's with the 40. Reload ladders, started out #9 laddered from 14.8 to 15.6. Too compressed at anything over 15.6 Titegroup did the whole 6.4 to 7.2 Getting way over the published velocity as expected, Using 155 XTP's. The thing is, though, Hot loads or weak loads don't make much of a difference as far as case separation. Case goes fully into chamber with extractor under rim so not unsupported blowout. Separation point about mid case. Found a source for 8-1/2" Extensions so adding another 3/4" + 1 more tungsten weight to the buffer. 14.6 oz buffer 3.6 oz additional weight 14.6 oz BCG Almost 33 oz reciprocating mass for the next trip to the range. Swapping BCG's with the 40. Think I'm going to back off on the spring go back to an orange or red. If this doesn't work, I have a 12" barrel to try. Also tried some PMC 180's, same.
