DAQ - rifling Twist Rates?
« on: October 31, 2018, 03:49:29 PM »
Anyone have any idea what the twist rates are for various DAQ airguns?

DAQ .58 LA Outlaw seems to like round balls the best so far
DAQ .58 Outlaw Pistol seems to like round balls the best so far
DAQ .458 LA Outlaw seems to like a bit heavier bullet in 300+ grain range.  So far 348 grain flat nose bullet is the best. I've tested.

I'm obsessed with finding the happy place ammo / molds for these things, and maybe just a little obsessed with casting them.

I think I've read that rifles that like round balls tend to have a faster twist rate. But I could be confused.

I guess what I'm getting at, is a barrel rifling twist rate, caliber, and velocity good predictors of what ammo an airgun might like the best?

Also, am trying to come up with a long range ammo for the .458 in particular.

Pushing a soft plug with a cleaning rod, is how I used to do it. Simply measuring the distance for one turn, was close enough. You can also do it with a borescope, with inch marks on the peripheral. All this said, one would think DAQ would tell you what it is?

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

Funny how Steve and I were thinking the same thing (barrel twist) and were texting about it earlier. The .308 Texan is 1:14. I'm not sure what that 'means' as far as performance. I found an old post from 2016 from Nick Nielson saying that larger bullets should perform better with that configuration.

I have to be honest, at the ranges I'm shooting (150 to 300 yards) I gravitate towards a flatter shooting (i.e. lighter) bullet because everything stays comfortably on my mildots. If I'm zeroed at 100 yards I'm off of my dots at 250 with anything larger than a 134 gr. slug. Granted this is nothing more than holdover, but I like to keep things simple and leave my scope where it's at. I don't mind minor adjustments but I'm not into adjustable rings and/or Cold Shot scope bases (yet)

I have both medium and heavy springs but I have not tried them. In fact I've even had my gun apart yet. Don't know if that's a good thing or a bad thing.

Scope magnification has a lot to do with hold over. I've found that at 16X I can zero my .308 shooting 135gr BBT's 810fps at 100yds and use the last mildot to hit at 200 yds. If I have it at 32X I can't even see the target in the scope to hit it.

Absolutely. I've turned into a 6X guy. My .308 is at 6X and my .25 is at 6X too. Seems to fit my needs and works for accuracy and simplicity. I love picking up my guns and knowing where they'll shoot without having to reference a notebook, make adjustments, or second guess.
