Technically, the barrel isn't angled up. During the zeroing process, we angle the sights down. This causes us to point the barrel slightly inclined so that the line of bore is pointed up, reference our line of sight and the bullet drop from the line of bore meets our line of sight at the desired zero distance.

Post subject: Re: Briley choke tube reviews?? The good: they are nicely finished inside so they don't get caked with plastic, they are pretty consistent in that they have the amount of constriction they should, per Briley's chart. They stay tight in the barrel even with hand tightning.

The biggest drawback is the barrels aren't chrome lined (which is why stainless steel is the next best for me) so I made this post to try and get a few pictures of mini 14 or 30 bores to see the rifling.

All DPMS Govt. profile 5.56 barrels can be chrome lined at the factory for $32.00 and the upgrade code is "UG-CH". The barrels we chrome will be stamped "CHROME-LINED", no stamp, no chrome. D.P.M.S.

Leaving it in the barrel protects and keeps the cleaning process going. But run a dry patch through last and get the excess out. Too much left in the barrel can raise chamber pressure.

The collet die produces cartridges with run-out far less than any of my other dies. Run-out as low as 0.0002" with most 0.001 or less. I also find it nice that no lube is necessary and therefore no "clean-up" other than a quick brush of the primer pocket. Accuracy for my rounds has never been better.

Nor are the barrels on M1, M1A, M14, and many other non-military semi automatic rifles. The majority of non-semiautomatic rifle made also do not use chrome lined barrels. I understand the value in chrome lining, but it isn't the be all end all. The Yugo M59 and M59/66 SKS have high quality hammer forged barrels.

As long as you're using quality flip sights and they're attached properly, you shouldn't notice any difference in accuracy. Originally Posted By blasterrider88: I wouldnt think it would make a difference as long as your buis locks up solid and in the same position everytime. exactly.

Hornady dies are fine but that makes them no better than other common brands. If the 'tight die' issue was specifically related to the use of One-Shot as a lube (per the OP), that may be what they call a clue.

Copper BB's in my optioning can corrode over time and create a rust like looking dust which can get in your Airgun. Steel BB's will rebound off of hard objects much easier potentially hitting the shooter. BB's do not work well in rifled barrels and can wear down the barrels.

Muzzle brakes are for recoil reduction Prettybird, not sound. Look up some muzzle brake pictures and look how they're shaped.

The better-made CHF barrels are more accurate and last longer than their non-CHF versions. They have double the chrome lining thickness and the chrome is more even since the hammer forged bore surface is smoother. It's only worth it if you do high volume shooting and need the extra half MOA group size reduction.

Practical Takeaway. By all accounts, fluting a barrel has little effect accuracy, either positive or negative. If done properly by a skilled gunsmith, fluting may lighten your rifle a bit, and it may have a subtle impact on the rifle's accuracy, possibly a positive one.

Yes, they prime. Thanks a lot guys, I thought they primed but because they don't have the primer 'dot' icon, I got confused. TIL about that visual bug. THANK YOU!

Barrels have different properties than chests. ... Unlike chests, setting two barrels side-by-side will not make a double barrel. Unlike chests, barrels can be opened regardless if there is a solid or transparent block directly above it. In the Bedrock Edition, barrels can be used as fuel to smelt 1.5 blocks in a furnace.
