I recently bought a new Skout EVO. Like most out there I realized there isn't a lot posted on them yet.
After my first initial shooting, sampling JTS 22.07 pellets, and the Skout/Corbin slugs, and some Altaros ATP King slugs (no tuning, just trying to use recommended starting points to see where these projectiles were), I decided I wanted to do an initial barrel deep-cleaning, followed by a thorough cleaning/polishing with JB Bore Cleaning Compound, a final polishing with JB Bore Bright, then applying hard wax before I started learning the gun's characteristics and tuning it.
I've read a little about a barrel having to lead-in after such a deep cleaning, and how accuracy needs several shots to come back around. So, I wanted to follow this process and show how it went for the Skout EVO.
I was shooting the 25" Lothar Walthar .22 barrel with the 1:15.75 twist rate, with JTS Dead Center 22.07 pellets. The pellets had been cleaned in acetone to remove oils and lead particles/flakes, then rolled around in a box lined with paper towels that had a light layer of Pledge spray wax on them.
I was told by Bill Gardner (Skout President) the speed sweet-spot for these pellets in this barrel is typically from 960-985 (he did mention Tim Swan was having some success pushing them faster, and Tim has posted videos showing this). So, I wanted to start shooting the cleaned & waxed barrel from the unseasoned state, watching what it does, and see how long before it starts to come in on the accuracy. I made adjustments to the scope turrets and the High Pressure Regulator (HPR) as I went along to get the initial tune on target and to the 960 fps start of the sweet spot to be ready to start full tuning evaluation for my gun throughout the full sweet-spot range.
The shooting was done in 5-shot groups. There were 15 groups shot on 15 small targets on two pages, each containing 12 targets. They were shot in order from Page 1 to Page 2. I covered these targets with shot strings on the FX True Ballistics Radar Chronograph.
String #1 - HPR 1530-1535 / LPR 190 / Dwell 25 / Page 1 / Target 1: 5 shots. Avg 994 fps / ES 7 fps / Std Dev 2.3 fps / BC 0.051.
String #2 - HPR 1510-1515 / LPR 190 /Dwell 25 / Page 1 / Targets 2-7: 30 shots. Avg 987 fps / ES 8 fps / Std Dev 2.1 fps / BC 0.061.
String #3 - HPR 1480-1485 / LPR 185 /Dwell 25 / Page 1 / Target 8: 5 shots. Avg 982 fps / ES 2 fps / Std Dev 0.7 fps / BC 0.063.
String #4 - HPR 1410-1415 / LPR 180 /Dwell 25 / Page 1 / Targets 9-12: 20 shots. Avg 961 fps / ES 5 fps / Std Dev 1.4 fps / BC 0.058.
String #5 - HPR 1410-1415 / LPR 180 /Dwell 25 / Page 2 / Targets 1-3: 15 shots. Avg 959 fps / ES 6 fps / Std Dev 1.7 fps / BC 0.057.
After such a thorough cleaning/polishing, it looks like it took about 40 shots for the accuracy to start coming back in. Once it did, I was pretty happy with this as my starting point for tuning/characterizing my EVO over the expected speed/accuracy sweet-spot range of 960-985 fps with the JTS 22.07 pellets. Looks very promising to me.
The one thing that stands out to me is the ease of tuning and consistency of single digit ES numbers. With my impacts, I always had to find the right spot on the curve to get the ES numbers to drop below and stay in the single digits. The EVO always seems to be single digit ES.
I also noticed the speed for a given HPR is a little higher now. Maybe the cleaning/polishing/waxing?
One last note... I was able to adjust and maintain specific HPR settings because I installed two digital gauges on the tank and HPR. These are from Outgun and are 25mm size with BSPP threads. These are the only gauges I've found (they are brand new to the market) that are 25mm, BSPP and display in BOTH Bar or PSI. So far they seem to be working great. These gauges don't read low enough to work on the LPR, but they have one coming out that is supposed to. I'll post on that LPR gauge when it arrives.
So far, I'm impressed.
