Ruger American/ Norma ammo ??

[ngamtns]

Having issue (twice now) with chambering a round, then when extract with bolt, the bullet remains stuck with loose powder. Have to take a cleaning rod and knock the bullet loose. It’s a Ruger American 308, shooting Norma 150 grain soft point. Is it the gun, the cheap plastic magazine or the ammo?

Does anyone have any suggestions ?
Thanks

Hummm.

I’ve got a case of that Norma 150s for my 308 (Tikka CTR). Cycles great and shoots like a laser.

I’d check the overall length on the ammo should be 2.800”. Sounds like it’s long and getting stuck in the lands. Maybe you got a box that’s out of spec? I’d measure and check, surely Norma would replace if that’s the case.

Guess your shell chamber is clean.

Thanks for the info. I am happy with ammo and the rifle other than the one issue. But that definitely is an issue. I will get the ammo measured.

The chamber is clean. I am OCD cleaning guns.
Thanks

I know your chamber is clean but there is still probably something in there that is causing the spent casing to stick. @BriarPatch99 made a post years ago that might help you. It concerned a different rifle but the principle is the same. I think I remember him having helped someone else with a similar problem much more recently.

If it works thank @BriarPatch99. Lots of folks have thanked that fellow for good advice over the years.

That guy knows his stuff! I feel like I know a bit but quickly realize there’s a lot more to learn around guys like that!

Well guys I spent this afternoon taking @BriarPatch99 advice. I thought the shell chamber was clean until this technique. I hope this was the problem and the fix. I have fed @50 rounds thru it and no problems.
I am going to measure all of the ammo just for kicks.
Thanks for all the advice and especially @BriarPatch99

Here is another reason I like this place so much.

Sounds like a short throat to me. If the bullet is jamming in the lands with ammo that meets saami specs then the fix for that is going to be a reamer or return to Ruger. Its ahead of the chamber in the throat which is the transition from the chamber to the rifling so chamber cleaning/polishing wont fix the issue unless youre so aggressive that you remove some of the rifling. Id reccomend you leave that to an expert.

PS bullets jamming into the rifling can also lead to higher pressure upon ignition.

just Had this happen with the wife’s American in 6.5. The chambers must be pretty tight on them or something. Cleaned it expecting to find debris but didn’t. Rifle works now so dunno

 

[ngamtns]

I cleaned the chamber and the throat with the wire brush/drill method. Hasn’t had the problem since
I kept the two bullets and neither have any gouge marks. Just faint scuff marks.

I hope it keeps running right for you.
