B14r feeding issues

Piggy backing rather than creating another thread.

I swapped my B14R to a Manners T4A with KMW Mk-1 bottom metal. Pillars installed and the action has been bedded just because, and I am happy with it…except about half way through the magazine (factory) the round jams at the breech.
Slight upward pressure on the bottom front of the magazine cures this and it runs an entire mag flawlessly.

I’m still scratching my head and haven’t figured a hands free solution yet, so I am soliciting thoughts.

Shims? Mag latch adjustment? Might the capture feature of the bottom metal be affecting the positioning of the mag?

The soft side of stick on velcro tape. Cut a 1/2" to 1" piece and slap it on the mag body to try and fill the void.

Or get a couple of mags. Mine does same thing with 2 older mags. One works just fine.

Springfield Kuna problems

waveslayer said:
Well guys, after the announcement of the Kuna, I got pretty excited at the price point. Picked one up, love the gun, it shoots amazing until...
Stove piping, then stove pipe again. I look down and a spring is sitting there with the brass case. The ejector is completely missing.

I call Springfield, they were nice. Obviously, sent in the bolt and 3 weeks later its back with a new ejector. Mind you it has maybe 45 rounds through it total.

Take it out yesterday, 14 rounds in, ejector is sitting on the ground in pieces... now it has a broken ejector again. WTF! I'm pissed and let SA know that. Off to SA goes the bolt again, I told them I want a new bolt and not just an ejector assembly. What a disappointment

That sucks.

If you keep the gun, you may want to just order a few extra bolts and tape one to each of your spare mags.
Frustrating. I thought that system had been proven out before they decided to bring it on board.

Wild ES with Tac 223 Load

Doom
N_Turs said:
Ok, So Im pretty new to loading rifle ammo. Just recently loaded up some 223 rounds for the Ar using Tac. I did some different charges around the lower end of the chart. All rounds loaded function fine and sense its just blaster ammo the accuracy was fine for what its being used for as well. My issue was the ES was 120 fps. I know tac isnt very temp stable but that seems like alot of variance. Im also in AZ so the morning temps were around 78 and midday 101.

What might I be missing thats causing the ES to be so high?
Im using FL sizing die with 21st mandrel about .002 tension with a slight crimp after seating because I was getting some bullet movement when charging rounds.

Loading on a dillon 650 using dillon powder drop.

Im trying to get better at loading these before I try and load some 77gr OTM's

Thanks in advance for any help

Unfortunately you really missed the boat. You told us it's an AR, the powder charge, and your ES, and pretty much nothing else. Yes you did tell us later it a Hornady 55gr FMJ. Without the actual load data, primer, case manufacturer, SD and number of rounds it's impossible to analyze your issue.

What could be the issue? It ranges from your "low charge weight" to "lack of neck tension" to "case capacities" or other issues.

Geissele national match won’t reset with match spring ?

BurtG said:
Putting a new Geissele national match trigger in a rd15 lower. Trigger won’t reset with match (lowest weight) spring in. Works fine with next higher weight(dmr) spring. ?

Ideas?

Seems like trigger is free in lower doesn’t seem to be binding

Have same trigger in another gun with 2 lb first stage and 10 oz second. DMR spring doesn’t compare

You have to tune your Trigger string, bend the legs down evenly so it creates more spring pressure and it will reset properly.

Why are AR15s so difficult to shoot for the average shooter?

Sheldon N
Bolt guns have shorter lock time and no reciprocating parts moving during the firing process, making them much more forgiving of poor shooters.

Bolt guns are more accurate generally, and likely are shooting higher quality ammo based on what the average shooter buys.

Bolt guns are much more likely to have a higher magnification scope making aiming more precise, versus an LVPO or Red Dot on an AR.

Bolt gun will likely have a better trigger with less creep.

Most commonly what you see is equally bad shooters with bolt guns and AR's. The bolt gun could shoot 1 1/2" groups but the shooter is hitting 5" groups. The AR with bad ammo could shoot 4" groups but the shooter is struggling to hit a pie plate.
