Radioactive

Finally received my ArmaLite spring if I get a chance today I’ll install and see what happens

I appreciate the offer but let me get the new spring in first and see what happens. You have been a great help and wealth of knowledge. I think this thing is on the edge of working correctly. Might just need a little more oomph. I’m just getting a little impatient which happens to be one of my shortcomings. I’ll kill time by contemplating my 6.8 build

I hear what you’re saying about bullet advancement - seen it in other calibers not just the 6.5’s and not just the long range rounds but hunting projectiles too. I wish I had gone with a little faster twist on my 243 ackley so I could shoot those heavy pills - oh well I’ll just stick to under 100 grain till it needs rebarreled. I didn’t chrono any of the 260 stuff yet- seems the second box of larue match is the one with issues maybe light on powder/ different recipe not sure but last box was cycling and new not - go figure I’m not sure what they (Larue)run in their guns I’ve never seen one in person but they did want me to use a red spring and heavy buffer when I told them I was having cycle probs maybe they went with 15 components i did buy another box of commercial stuff 120 gr fusion just for another data point (4 different loads) and to stay ammo’d up for reliability testing maybe I should just load up some bare bullets and put a couple hundred rounds through it to break in - it would suck if I have to do it single shot style. Wouldn’t be too bad if it was a bolt gun or locked back each time.

I agree with that logic and I’ll wait for load development because I’m gonna shoot coated bullets and don’t want to bounce back and forth between coated for development and bare for cycle check (barrel cleaning) - just will take a little longer is all

Yup just some early morning before coffee musings -waiting on new spring before going forward seems like it takes forever when waiting on parts and days off this will be a range only gun wouldn’t want to pack it very far i have several hunting rigs (no ar’s) although my next build will be a 6.8mm in ar package for hogs

I was thinking / wondering if I have it close should I do my load development then tweak the gas or get it reliable then develope my load reliable then load if it was going to be a do anything gun but this will be for distance so will probably only see 1 or two loads for it’s lifetime thoughts / suggestions?

After I get the new spring installed I’ll see how it does then decide if I need to open the port some more ideally I want it to cycle everything I run through it whether I can do it without being overgassed remains to be seen

Gas tube protrudes just shy of 3/4” probably11/16” looks to be where it should ordered an ArmaLite spring Got some more data after clean and lube(wasn’t very dirty). Would not lock back or cycle far enough to pick up next round with the larue secret 130 grain match loads or the federal premium 140 grain game kings. It did cycle next round and locked back with Hornady superformance 129 grain sst’s. The larue was a different box than previous successful attempts. It seems I’m on the cusp of being properly gassed. Will wait and see how it shakes out with new spring. here is pic of gas tube

Will get a pic and measurement of the gas tube in the receiver. The gas block is not adjustable. I’ll have to order the Armalite spring.

Thought about starting new didn’t want to lose anything and couldn’t figure out how to cut the bs out

Well.... still having issues finally had some time to put some rounds through the gun after opening up the gas port - cycled for about 5 shots then would eject but not pick up next round this lasted about 4 or 5 shots it got worse and finally wouldn’t eject still short cycling did a quick spring change to a shorter lighter adjustable stock carbine sized spring and it ejects and picks up next round but not enough spring press to fully lock into battery will break it down for another clean and lube currently almost dripping wet - not even 2 full boxes of ammo run through checked the gas block still tight hasn’t moved seems clear when blowing through it seems like a friction related thing but wanted some other opinions

I have a p mag a hex mag a dpms metal mag and an ar stoner metal mag they all seem to work so I was just wondering what others have experienced as far as reliability goes

I have a bunch of p mags for my 15’s but what works best in the dpms pattern large frames? This is for 260 rem round so so should not present any abnormal situations. should I stick with p mag or try lancer, hex etc? whats your preference?

New Harris bipod, shooting mat, small rear bag and a pod lock for the harris thinking real hard on a ChargeMaster lite but haven’t pulled the trigger yet

Purdy for sure i may try some of those Hornady eld’s I wonder how the tip would handle being boron nitride coated since they get vibrated with the fixins

What twist? I have 1/8 and thought the 140’s would be about as heavy as I’d be able to stabilize couple that with the mag length and I’ve read the long heavies become problematic id like to run something in the 140+ range but am worried about stabilization so I figured I’d start with 140 and lower and see what it does one thing I don’t want is to waste a bunch of time/money/barrel life chasing a pipe dream this will be a fun target/steel gun for 1000 yard stuff. I have a bolt gun in 243 ackley that I’m happy with for hunting and a 338 win mag for the big stuff. My 5.56 ars are set up as defense/tactical shooters.

Anyone have a 260 rem load using reloader 17? Going to work up something for pushing 123 gr lapua scenars and 140 gr berger hybrids

Blind guy walks into a bar and orders a beer he then asks the bartender if she wants to hear a blonde joke the bar tender says I’m blonde and a body builder the gal playing pool behind you is a bad ass blonde biker chick and the lady sitting at the end of the bar is a black belt and she’s blonde now you still want to tell that joke blind guy says well not if I’m going to have to explain it 3 times

Toad wouldnt want to hump that in the mtns of Montana chasing elk all day

Upper 10lbs 7 oz lower 2lbs 10 oz makes it 13lbs 1 oz give or take

Roger that

Tried some commercial moly ammo just to shoot it. Had no expectations got nothing from it just free ammo I burned up wanting to up my long range capability with my latest build

Didn’t think of that - will do

Maybe I’m off base with the comparison since I don’t own any “real” shooting bags I am thinking of purchasing some and a real shooting mat too - not just a piece of carpet I throw down to delay the ants

I do all right shooting from a bipod it just feels like I get some bounce and takes more adjustment to get back on target than I have to do when using a bag my bag is usually a back pack contents adjusted for range or hunting. Range has more clothing, coat, blanket etc while hunting has my hunting stuff and a few small clothing items not as soft and squishy
