Thank you! That is EXACTLY the information I was looking for!

Glad you nailed him just before you were taken up into the alien spacecraft.

Poor man way to hunt hogs, green lights!

Apparently it works! What more can you ask?,

Got another one with the 135gr FTX.

My wife Joyce and I just finished a enjoyable and successful hunt down by Del Rio at the Bar JP Ranch. Shots were from 125-275yds and we used the Hornady 135gr FTX which performed flawlessly with most shots giving full penetration on these big tough African animals.

My wife Joyce shot this 10pt from 275yds with the 135FTX, it took about 5 steps and was down.

Very nice animals Bill! Curious if you are using a 16" or 18"?

16" Ranger LW with one of our Quell Ti suppressors Trijicon Accupoint 3-9x40 crosshair/green dot

My suppressed guns are all 14.7" or 16" and non-suppressed are 18"

Put my little cousin on his first deer today. 130gr hhc @ 70 yds. Perfect lung shot. Ran less than 40yds.

AWESOME and congrats. I love it when kids are able to get out hunting.

This last weekend was family time at our property. I get a weekend or two to hunt with my oldest daughter (she is a teenager now and has “stuff” going on). We sat for several morning and evening hunts waiting on a nice old buck we have on camera. We passed on turkey twice and she really likes turkey nuggets so that was a difficult decision. Well, Sunday morning this really old buck showed up, not the one we were waiting on, but an old one that we could take. She dropped him in his tracks from 125 yards with the 300 HAM’R using the 135gr FTX ammo. We had a great time setting and watching nature this weekend. My favorite time I spend with her. I also dropped these two piglets with one round of HAM’R 135gr FTX ammo. I love the holidays!

I need an advice regarding my 300HAMR barrel (Ranger 16.25", 1-13).

After shooting suppressed ~25 rounds (mostly 1st time fired converted LC brass), I am experiencing random "click no bang" with no signs of firing pin reaching the primer and a later failures to chamber.
At that point, rounds that manage to fire are just spraying the target (when the barrel is clean they group just fine).

Swapping the bolt, charging handle and lower doesn't help.
The only thing that helps is cleaning the chamber, which is completely black at that point (note, the rest of the gun stays relatively clean).

I have never experienced that much of carbon in chamber and lugs after only 25 rounds and if I did the guns would continue to work in that condition.

What can be wrong with my setup?
Is the barrel out of specs and allows too much gas into the chamber?
The headspace is off somehow while the bolts I tested have been headspace checked using gauges in several 5.56 and 300blk uppers?
Should I blame freshly formed brass being under sized?

I have very limited experience with suppressed systems but there are some things you can answer that might help with diagnosing your problem.

Buffer weight?
Full weight bolt carrier?
Adjustable gas block?
What bullet and charge weight?
Everything works fine unsupressed?
Did the brass show any pressure signs?

My thoughts are that the load isn't completely forming and sealing the chamber, leading to all of the excess crud and causing the bolt to have a weak cycle, which is causing the failures to chamber and not fully going into battery, which might be why you're not getting primer strikes on some rounds. If it's over gassed, the increased pressure in the system moves the bolt faster and can cause the bolt to bounce out of battery or to unlock too early. Increasing the buffer weight or using an adjustable gas block could cure this.

Thank you for the reply.

My setup consist of: Adjustable gas block, lightweight BCG, lightweight buffer and 10% reduced buffer spring.
As you can see I am obsessed with weight and recoil ;-) and that combination functions flawlessly in several 556 and 300blk guns.
Firing cycle is optimized for lowest gas volume that would cycle with brass ejecting at ~3 o'clock un-suppressed.
When the chamber is clean, the gun and spent cases shows no signs of anything wrong (besides larger than usual deposits of soot on the cases which I assume is normal for most suppressed guns).
Once the chamber becomes dirty, the rounds that failed to fire require force to be extracted an manual feeding (pulling and releasing charging handle) is required to feed the following rounds.
Later on, I can't even force the cartridges into the battery using forward assist.
I think my gas/buffer system is fine but something causing excessive gas blowback.

Regarding the loads, I used freshly converted LC-20 brass and powder charges corresponding to middle charge minus 5% which depending on the projectile is ~25gr+-0.3.
Also, factory loads and my loads with factory brass function perfectly fine and some of the spent cases look cleaner but not always, go figure...

There are just too many non standard parts in your setup to give a good diagnostic. I don't think the fact that you're forming the the brass is your problem(though it's possible) but maybe your charge weight depending on the bullet. 25~ grains isn't much for bullets less than 150 grain. Your load might be borderline for fully forming the brass and getting a good chamber seal.

Honestly if it were my rifle I'd go to a mil spec bolt carrier, spring and carbine buffer. After that I'd adjust the gas without the suppressor until I had reliable lock back on an empty magazine then add a bit more for reliability's sake or go with a non adjustable gas block. Go fast parts are fun but if a gun's not reliable it's just an expensive paperweight. And the Ham'r doesn't recoil all that much.

Thanks for your suggestions.
I am going to try mil-spec setup with my next batch of converted cases.
Also, I'll compare dimensions of converted and factory cases after firing.

Though, It would be nice to see which powder charges people use to fire-form converted cases with 125TNT and 135FTX bullets, just to make sure I am not "under-loading" as you suggested.

Measure the OD of your loaded ammo at the neck, my guess is your LC-20 cases have a neck wall thickness that's too thick. We've ran into this is various brands and lots of 5.56 cases.

My wife Joyce took this nice 10pt Monday evening just before dark from 167yds, DRT with the 135gr FTX

FYI we have a big sale on bbls for Black Friday

She is finding some beautiful deer. Congrats.

Midway just got 135 FTX's in stock. I ordered three boxes.

Seriously, she is laying them down

This thread has cost me a lot of money so far. . . and I'm glad I found it after being pretty underwhelmed with 300BLK terminal performance.

I got a Ranger 16" HAM'R upper assembled a while ago & stacked a solid 18+ hogs last weekend with the 125gr Pro-Hunter loads.

I got on the Holiday sale & ended up clicking on a 1-15 twist Protector 16" barrel on my phone instead of the 1-13 twist 16" Ranger I meant to order.

Has anyone experienced dramatic POI shift with a can on that light weight of a barrel profile?

When Running a 14 to18oz can Is it in my best interest to give this to my dad & order the Ranger profile barrel or will I be reasonably good enough for 2-3 shots on the Protector profile with a can of that weight?

Also, I've read this whole thread a couple times over the last 2 months but don't recall much specifics on the 135gr FTX loads. Has anyone had a successful load they'd like to share for that projectile? Hot-Cor & Pro-Hunter projectiles are rare as hens teeth right now but I have good access to nearly unlimited 135 & 150 FTX bullets.

Do you have any recommendations on twist? I see that the website says 1-15" is the best all around. Would that be your choice for 125-135 grain hunting rounds?

Edit to add: It looks like almost all of the barrels on sale are 1-13". Are they not selling as well?
