I was able to fire my 20" sts fluted HB BCA Grendel barrel yesterday for the first time. (Just about 20 rnds of 123 & 95G Hornadys.)
I was concerned as the very first thing I did with my barrel was drop a loaded bullet into the chamber and when inverted...it did not fall out. :eek: But it was oil, not a bullet into the rifling... I ran a patch down and to my surprise I had powder residue. I ran 4-5 patches with solvent then a brush then two dry patches before It was coming clean. SO at the very least tis one was test fired.
Yesterday, I loaded it up and test fired... one round and altho it ejected, it didn't pick up a new cartridge... I repeated this three times. I swapped lowers, with my 25/45 and it ran fine. I checked and somehow used the wrong main spring.
I did not measure the chamber, but 123 A-max and 95g SST's seated to 2.257 do not tough anything. Because of the MS issue I never really shot for accuracy, But the 123's produced single ragged hole and the 95g would touch holes at 50 yards.

Just got barrel #4. They swapped me a stainless 5R for the Melonite conventional rifling with the short throats again. Both were 20" straight fluted. This one is 2.304" to rifling with the Nosler 120 BT and a factory Hornady Black drops all the way in and slides out on its own! Finally!!
