What Bore Do You Use?

I am really liking those Lurker Eigenbarrel .679 barrels. I got one for my pump, and am using it on my mag too.

Gotta post a correction... The other day it was 104* here, 90%+ relative humidity according to the handheld hygrometer. I was shooting Marbalizer (test) through a .695; anything smaller was causing strange spin and resulted in barrel breaks. The paint didn't look misshapen but it did seem a lot less consistently sized than usual (I picked a few from different bags and parts of each bag and the digital calipers don't lie).

Apparently, recently I've been using .695

Didn't think New England ever seen 104', but 90% humitity sounds awful at any temp.

The news reports from Logan Airport said "a nearly record breaking 100*" but my thermometer, the one at the bank in town, and the one at Hanscom Air Base said 104*. One of the HVAC techs at work said he'd clocked 106* at one point of the day.

The humidity was terrible; I almost didn't believe it when my HZ unit said 91%... I figured the heat was getting to it or something. Later that night on the news they were talking about a 96* dew point, so I figured their measurements were just as shady as they were with the temps, and my unit was right. Some kid at a restaurant down the street from my business almost died...

barrel length, boring & bore size ...

I'm interested in hearing what bore mag users are using these days.

If you could only have 1 barrel bore to choose, what would be the best choice?

Near exclusive .682 out of my freak kit. I use it so often I've thought about just getting a straight CF .682 and selling my kit all together.

I shoot a 0.693" insert in my equation barrel on my mags and a 0.696" empire on my angel. They work great on all paint. Always err on the size of large.

This obviously won't work with an Autococker, and goes against all test results here.

Overboring is a bit of a problem for cockers. For the same reason, it is also a problem for most pumps (AGD pumpmags being the exception here). Because the insertion of the ball into the chamber of a pump is human controlled, a perfectly matched barrel is preferred as long as the balls are consistenly sized. This allows the use of the largest possible barrel id without allowing any rollout.

The video does go against the early testing done by AGD desing, but AGD testing is based on guns with a high bolt impact. Newer style guns, especially ones that use lower pressures to control the bolt dwell that affect velocity, will be more greatly affected by variances in the paint. In this case, overboring takes care of the problem and creates a more consistent marker. The more fragile tournament grade paint also exaggerates this problem.
