Range Report - Update on my .308 Issues

[Black_Sheep]

Thanks to all the guys that responded to my previous thread regarding short stroking/fail to feed issues. I’m happy to report that my .308 shoots like a dream. Tonight I ran 75 rounds through the gun without a single stoppage, even after several double taps in quick succession. The bolt locks open on an empty mag, just as it should. I’m so grateful after suffering such crushing disappointment 2 weeks ago. I really appreciate the help, thanks so much.

You guys rock!

The fix? Enlarging the barrel gas port with a #44 drill and swapping the 3.8 ounce buffer and spring for one of Slash’s 5.5 ounce heavy buffers and corresponding buffer spring.

Excellent news man!  Amazing...it seems like every rifle functions with the right gas port and correct buffer.  And if it doesn’t, those items can be ruled out. The 3.8oz buffers were a terrible idea in these bigger rifles. And making the gas port smaller in an attempt to compensate has proven to be the wrong way to go. Happy it’s functioning and now you can play with other parts if you want to.

I got it dialed in at 50 yards, the next logical step will be to take it out farther and try some different factory loads to determine what the gun likes. Hopefully it can consistently shoot 1 MOA, if it does I’ll be satisfied.

Sounds like you're doing it right man. Glad to hear that it's running properly.

Glad to hear it is running well.  Now, what will your next build be?

[unforgiven]

I'm glad you got it going.  Its amazing how the guys on "the other place" were still making guesses (and wrong ones) on how to fix it right up to where you said its fixed.

Right, I guess we know who the real experts are👍

Outstanding @Black_Sheep, glad you got it working as it should!

Black Sheep - That is exactly what I needed to do with my build. 90% Aero Precision parts with Ballistic Advantage 20 inch heavy barrel.

I did as you - #44 drill at the gas port, used an Odin adjustable buffer at 5.45oz and Orange spring from Sprinco. Like you it shoots great now. Eats everything I put through it.

And I absolutely agree that the folks on this forum ROCK!! As for your comment on a 1 inch MOA. I'm not a professional, ex-military or other kind of marksman. But I was able to get 1/2 to 3/4 inch groups at 100 yards on a bench with Bi-pod and rear bag. Now if I could get hose numbers without a rear bag and in a prone position that would be great.

Take care and enjoy your new toy   😃

So, @1500VHO, what's your complaint? 😀

 

[1500VHO]

Hi Sharpshooter,

No complaints at all...  I just wish my eyes were better, my body was back to about 40 years ago, and know everything I know now...   LOL

Take care

When you get old enough to have time to have fun with hobbies.  You still don't have enough time to do everything you want.  Because when you get OLD it takes so much more time to do anything now.    🥵🥵🥵

One day, they'll wise up a little, and either figure it out and start listening.

 

Or not.
