Out of my G 34 and stock barrel:
125 gr Blue Bullet
4.4 CFE pistol, CCI Primers, Win brass, 1.15 OAL, AVG MV 1054, PF 131
4.8 CFE pistol, AVG MV 1107, PF 138
There should not be any issues with the versamax. As the shotgun heats up after shooting slugs, some people had issues with the mirage when shooting camouflage shotgun barrels.
My black Versamax had the same stainless mag tube.
No issues running Titegroup with Bluebullets, I load it all the time with no issues. Any of the above mentioned loads look good, just chrono your ammo to optimize the load.
I tested the following loads using a Glock 34, stock barrel,125 gr Blue Bullets, 1.15 oal, CCI primers, military brass, CFE pistol:
4.4 gr 131 PF avg
4.6 gr 135 PF avg
4.8 gr 138 PF avg
The average was taken shooting 10 rounds per load
Dawson Precision, I have had zero issues with mine on my 43. I have a FO front and rear black. They shoot point of aim, point of impact. I've only shot my 43 up to 25m.
I've reloaded using the standard powder bar down to 2 grains of Titegroup and had no issues. I checked the first 10 rounds and they were consistent. I also chronographed the ammo and there no significant inconsistencies.
I've used an "Archos" in the past. Its a small Android tablet. I'm not sure what they are making now but I used one about 3 years ago that had a 7" screen.
I do use a the Shooting Chrony. It's reasonably priced, but I can't get the printer to work reliably. I would not say its the best but it gets the job done.
