Everyone brings up some very good points. So I’m gonna chime back in with how this is all relevant to me….
1. I didn’t know of CMMGs reputation for “tight’ish” chambers until several years after I bought it.
2. I knew well enough to break in the rifle with my planned ammunition before I stocked up in quantity. I broke it in w/ 180 rounds of XM193 & 500 rounds of Wolf polymer.
3. The rifle ran flawlessly.
4. I bought 5k rounds of Wolf polymer back when I could get it for $150/1000.
5. I knew Wolf is inferior ammo, I knew well enough to buy Polymer vs. Lacquer.
6. I use Wolf exclusively for training purposes; I stash XM193 for anything else.
7. I became a professional M4carbine.net lurker while I had downtime during my mandatory vacation overseas.
8. I have yet to see a post on this forum about CMMG that didn’t include the words .223 chamber.
9. I figured I’d be preventative and start a debate about reaming vs. “If it ain’t broke don’t fix it”.
I really just want to know the Pros & Cons of chamber reaming. At this point if there are any Cons to reaming, I’ll probably upgrade to a new barrel. This is because, “I want my rifle to have zero Cons”.
The whole reason I decided to feed it 500 rounds when I get back is not to “torture” test it, but to give CMMG a fair shake. So far I have no complaints, I just want the peace of mind that my rifle will “run as well as it can” on Wolf. I know Wolf isn’t perfect, but I want to make sure I don‘t experience any “stuck casings”.
Thanks a lot.
We few, we happy few, we band of brothers;
For he to-day that sheds his blood with me
Shall be my brother; be he ne'er so vile,
This day shall gentle his condition;
And gentlemen in England now-a-bed
Shall think themselves accurs'd they were not here,
And hold their manhoods cheap whiles any speaks
That fought with us upon Saint Crispin's day.
