Spring life is always a good debate. I always rotate mags or just unload them for a while , which happens when I disassemble them for cleaning any way.

Got some time to get to the range today , conditions were, gusting winds , 78 deg. & rain .I had some Chronograph problems , so the data I want is not complete. Came down to a weak battery, I shot a string after checking all else & it worked fine . Seems like this Chrono goes through a battery every time I use it . Most of what was shot was flu length sized with a Redding " S " type bushing full length sizing die , using a 0.336" bushing.Had problems with my DPMS mag ( go figure ) it would not hold back after last round in both rifles & various loads , so went back to the Gen III PMag & no other function problems after that. No high pressure signs on any brass , with any load I shot . Both rifles seem to like the Nosler Match 175's , even with the high gusting winds , both rifles had some good groups . With the wind I didn't pay all that attention to how well they did ,but was impressed with this bullet right away. I know all the long range shooters probably knew this bullet shoots well , but I'm new at the long range & heavy bullets.

I had seven more test loads for both rifles ,but the Chrono not cooperating & the impending rain kinda put them off. 98 I edited the other post & added the 20" bbl. , 42.5 gr 4064 ,with WW primer

The problem I had loading IMR 4064 with the Tac X bullet & with loading data from Barnes , the powder was so compressed , the bullet would stick to the seating stem or pop the bullet back out , because of the different shape of the Tac X bullet . Emailed Barnes & was told to polish the inside of the bullet cavity of the seating stem , which cured it , but I could not get them to print well with even WC 846 , which had plenty of room in the case. Just too expensive to work out the the right combo. I think if using the WC846 , which is a pull down ball powder , you will not have a problem with it or a similar ball powder. The loads I spoke of in my previous post are all loaded with IMR 4064 & none are compressed loads.

When I used to carrie a 1911 (not legally , yes ,I did that for a very long time ) it was cocked & locked . If you think you have time in a stressful situation , to rack the slide , go for it , myself, its enough to take the safety off . I like my newer carrie pistols , with no manual safety's . I've been carrying a M&P Shield lately & I like it , but still carrie my PM 45 , when feeling the need .

The 150 gr. TTSX 308's are very good shooters , I load some for a couple of hunter friends ( 30'06 ) . I have also loaded some of there Tac X 168 gr bullets & had mix results & too dam expensive to play around with , when I know what results I can get with bullets half the cost . I even had problems loading them , had to email Barne's . I also load Hornady SST's ( 30'06, 7MM-08 & 270 ), they seem to be a better grouping bullet & the guys I load them for are very pleased with the end result on Deer. I think you will find that every chamber & barrel are different & one may or may like a certain load , bullet , powder or primer . Just what I have found throughout the years. Have you posted photos of the offending ammo's spent cases ?

Looks like the hand guard survived . Looks like the bolt blew into the Carrier. Can't tell if thats a Billet upper . They can say the Larue mount saved them. Hope no one got hurt .

Could be a combination of both , one too stiff & not releasing the spent case & the other not pushing the spent case from the bolt face .

Were the primers overly flattened ? Showing little or no distinction from the edge of the primer & its pocket ? Low pressure loads may show a slightly cupped primer indentation , but not a flattened primer, still having a distinct out line of the primer & its pocket , rounded primer edges where it meets the pocket ( like unfired) . the primer will still be flattened some what ,but not to the point where you can't perceive its edge. Its the overly flattened primer that looks like it has flowed into the edges of the primer pocket, that are a sign of over pressure, of course that will also have a pronounced firing pin indentation cratering. Different bullet manufacturers & weight bullets may need different COL's because of the various bullet olgive's . You can have one manufactures bullet , that will be ok , than the same weight bullet from another manufacturer , could show pressure signs .Going to different weight bullets , even with the same manufacturer , may have a different Olgive or in a different place with in the length of the bullet & may need a different COL. You could also get int to how different manufacturers make there bullets , harder jacket , softer jacket , same with the lead core . All will show different pressure signs , with the same loading . Then you have the solid Copper bullets , which are a different beast & in my experience , can have a larger powder load with out showing the same pressure signs as a lead cored bullet.

Nice job .

This thing is permanently attached to the scope , to make sure the rifle is level from shot to shot . When I read how much a shot can be off from the scope cross hairs canted even a little , I had to check this out . The further the shot , the more off it could be , just from canting the scope one way or another .

You may have found the barrel/chamber sweet spot . Of course , that could change as the action breaks in or not .

Ya, that's part of it , photos also. Please , there I said it !

Steel frame revolvers only , not the Brass frame ones .

I have extra springs if you need one , with or with out the rubber finger inside. If you had to compress that spring with pliers , I wouldn't trust it .

You said you used a smaller pin , did you try to manipulate the extractor in the bolt body with out a spring & o-ring ? That would tell you if it was a fitment problem with the extractor in the bolt or the spring set up .

I started loads at 39 gr. ,39.5gr. & last 40 gr. of IMR 4064 & Nosler 175 match bullets , I will have Chrono data Monday. I have six different loads & two different powders. Noslers load data reads 43 gr. as there max with a 97% fill of case . You had to hear some crunching when seating the bullets . <thumbsup> Nosler has the 39 gr. as the most accurate , in there tests , with there barrel .

I would call them . I emailed them months ago with a question & have not heard back yet . Maybe it was in my spam folder & I routinely delete it , maybe they didn't like my question or didn't want to answer it . It was about there barrel gas port size .

I'm not familiar with the powder you are using . Do you have experience with reloading or are you new at it ? Just so we know where to start .

Good question .

I think all AR types are of "Stoner "Design. <thumbsup>

The cracking of the primer compound could also of happened when de-priming it from the case. If you look how Primers are packaged ,being shipped & handled for innovatory , it wouldn't take much for some one to spill something on the package or even be around certain chemicals or gases for it to compromise there performance. These Primers are the first in over thirty years of re-loading , that I personally have had a problem with, so I don't think this is a wide spread problem . Luckily for us , re-loaders. I also thought the poster's primer looked to have burnt or partial ignition around the Anvil .

Although this looks like it has some discoloration on the anvil , the primer compound is intact. No doubt in my mind the flash hole was clear. I have no problems with other primers in any firearm. Just to show it was hit , though de-priming it seems to make it look less of a hit .

No Bags on the Pan's to put anything in . <dontknow>
