same rounds different gun....... it took me a while to figure it out but had some (bought) reloads that were jamming in a friends new gun but ran in mine.. long story short... finally measured some of rounds not yet chambered in his rifle... turns out reloads were off by avg .0018 when dropped in case gauge... unless you have really good eyes or ran a straight edge over loaded case gauge, i missed these b sight alone .... i found out by using stand comparator on a loaded case gauge turned out ammo not passing case gauge.... it appears that the first slam rifle either resized ammo or chamber in my gun is looser.... before you send it back take a real close look at reloaded cartridges before you chamber in rifle with stand comparator if you can get hands on one. check sized trim legnth and if loaded cartridge is proud in case gauge. You may need to dual down sizing die..... if i didnt get any data from stand comparator. i was going to buy jp gauge like big ed suggested

if your brass and loaded cartridges meet specifications what is curious is that it used to run great for "2 matches" but now having error..... sounds like mechanical failure/error maybe the problem is the rifle/mag? head space? blem in chamber? bad extractor? other bolt/bcg error?

What's the difference between a chick pea and a garbanzo bean? i've never had a garbanzo bean on me.........

HowIt bruddah? welcome to da forum. must be nice shooting in the islands!!!!!

What length of sized brass? are you running flat edge over case gauge with loaded ammo? what case gauge are you using?

While not one of you original choices. I'd consider a sp-o1 with any of the custom " pro package" be it czc, Cajun, accuracy... I doubt you'll see any accu --- accuracy difference unless you ransom test it,. Or are in the top 5% a fully stroked sp01 can be had for 1k. add extra mag f/o sights grips and still come equal or lee$$ than shadow pricing. And come out with a better gun.

i'm thinking buy the sp-01 with all the work done @ cajun gun works for about 1K i parted my build out slowly, I would just go full cajun if i did it again https://cajungunworks.com/product/91152-sp-01-998-00/ if you DIY spo1 $700 parts $250 so the complete package from cajun make $$ sense all you will need to ad is f/o sights plus this gets you a gun way better than a stock shadow but in my memory serves me the shadow is a saftey version spo1 with firing pin block removed with f/o sight . and i think different trigger, i also recall a 3rd mag with shadow. at this point you are are about $200 in parts. spacer to replace 14 lifter, i think the remove or mod the FPB , fiber optic sight, 85 c trigger

I cull out cbc pierce and Aguilla,. But not for oal reasons. These headstamps would get big "hips" and fail case gauge or ftf. Not sure how brass affects coal. ogive is better measurement than oal. But that's a different topic. curious how much was you oal off? And how much did it change accuracy?

the short time i was in the army never saw a pin walk, all my military friends, and leo that i know of that have shouldered an ar/m4 never saw a pin walk. i have always thought anti walk pins were just a result of marketing, i even had some and sold them, i didn't believe they were necessary until yesterday.... luckily i was single loading for load development i loaded a round, released bolt click to semi squeeze trigger .... nothing took lower off disconnector not holding hammer switched lowers...... continued trouble shooting later found that trigger pin had walked just a bit, just enough to cause error, this not on a drop in trigger, but tuned mil spec. pushed pin back in functions 100% i just ordered 2 sets of anti walk pins.... i am now a believer

if you pull primer feeder by hand will it load primer? maybe try adding a little more bend in it? after re reading my next guessis you didn't align primer assembly/bar before tightening everything down.... did you rotate primer magazine tube until is clicked and seated in?

I know nothing about s&w m&p or any striker fired gun..... but local gun store has some very very clean buy backs in .40 (and inexpensive) no one at range or gun store has definitive answer. im hoping there is a drop in part with minimal to no gunsmithing what about whole upper?

i was giving the mag tube a wipe down and noticed it is loose i was able to turn it by hand should i lock-tite it in, or just hand tighten

ok im frugal i take a a used cardboard target cut out a zones. lay this on drop cloth paper draw outline with marke draw A zone with pen or pencil https://www.lowes.com/pd/Blue-Hawk-Paper-Drop-Cloth-Common-2-ft-x-140-ft-Actual-2-33-ft-x-140-ft/50053433?cm_mmc=search_google-_-FY15 Paint-_-Dsa Paint-_-_cat%3Adrop cloths&k_clickID=ce3732b9-075a-40ad-affa-3398fdbc8989 my calculations have it @ about 56 targets for $10

this just happened to me its a stretch but check it anyway. on the roller bracket assembly part #14280 there are tiny screws that that if loose will cause primer problems.... easy check is to pinch and wiggle plate.. its the part you put base of brass on before sliding it under shell plate

patterning left and high @ 15 yards with wally world federal bulk pack i am at about 100 rounds down the tube.... should i think about shimming yet?

wire pecan gatherer vs ammo up http://www.ammoupusa.com/compact has anyone used both any reviews?

my grip strength is getting more consistent, having the captains of crush in my car (office), mental practice my opinion is if you have excess strength your 50% effort is much stronger than the weaker my job is not manual strength intensive so i have to make up for it getting precise grip placement , more so trigger hand , so gun and sights index correctly is my issue, guessing i'd drop .4 or more on my draw to first shot average........ other than more dry fire is there anything else to try ?

No site suggestions but would be glad to chat about it, i use use a sand sock left hand for rear bag and elevation.. Well rice sock. I'm trying out a sock with large sand/ tiny pebbles now. get a body position that gets the rifle to recoil straight back .....usually in line ish with rifle, faster second shot acquisition. often over looked tool is. Scope level. I did't break sub .20 moa until I started using one. find out if your gun and shooting style likes to "load" bi pod. Parker hale style pod is easier. Harris not as easy. Some shoot better without loading..... use a sleeping bag mat if your going get a lot of belly time. Observe and learn breathing control / pattern, pulse timing

respectfully disagree taper crimp is necessary, it is hard to measure maybe you are speaking of roll crimp......

Did you try blowing it out with canned air.. Most of the tighter gauges are not dirt tolerant. Take fails and try different hole.

I'm tumbling in walnut harbor freight tumbler nufinish ihavent gone over 1 hour...... Now im curios to what longer tumble looks like...... i always wear wear a mask when separating brass fro media.... And do it outside..... how many runs on dirty brass before you change media?

Re: oal..... I usually load 2.25. But was wondering if any one tested deeper seating for more accuracy?

Thanks what oal?

I'll doing load development for; 1-7. 16 " ballistic advantage Hanson, Wylde 1/7 white oak bbl 18", Wylde i have. 55, 62, 77. Over xbr 8208, and lake city brass
