Encore
barrel: 16" Bugera
Suppressed: AAC Cylone
Bullet: Hornady 90 gn XTP
Powder: Trail Boss
Brass: Converted range pickup Nickel
Primer: CCI 400
Charge: 4.8 gn
OAL: 1.815"
OAL with Hornady bullet compator 1.632"
Crimp: Very light
Velocity: Ave 1039 ES: 54

Note: I had to set the bullet out very long for accuracy, but once found it shoots great. The pic is 10 rounds at 50 yrds using a Nikon P-300 scope. I called one flyer just below the group. The black dot to the right was aim point.

Rifle Used : CVA Scout V2
Barrel maker: Bergara
Barrel Length and Twist : 16.5" 1:8
Bullet Used: 86gr Hornady RN for .30 Mauser
Powder Charge and Brand : 3.8gr Unique
Case Used : 5.56 LC
Primer Used : Tul ammo small rifle (Standard)
COAL: 1.740
Chronograph Velocity: Don't have one but 4.2 gr cracked supersonic
Notes: Quiet without suppressor--~.22LR subsonic noise.

This was the best of a ladder:
3.2gr (1.1" group with sooty brass--didn't seal chamber)
3.5gr(vertical stringing 2.5")
3.8gr 1/2"
4.0gr (1.6")
4.2gr(2 shots in 1/2", the 3rd cracked supersonic and was 1" higher)

Other Impressions: It's easy to make these short bullets into inaccurate loads. They wanted to cock sideways in the brass and would shave the bullet tip if forced. Also seating the bullets slightly cocked can affect neck tension.

Shot one 4.0gr load into a gallon jug and it blew it up pretty well, bullet exited with the back of the jug split top to bottom.

Sub loads with light weight bullets in 300 BO

Remington SPS Tactical bolt gun, 1:7 twist, 16" barrel, Yankee Hill Phantom suppressor. I plan to see if there is a difference in these with my new Liberty Mystic
chronographed at 10 ft. Approx. 1,000 feet above sea level

Hornady case
CCI small rifle primer
COL 2.111 to 2.135 (depending on bullet)

This group using 150 gr Sierra Spitzer SP flat base
7.0 Little Gun
926 to 945 fps

7.1 Little Gun
980 to 995 fps

7.2 Little Gun
1,080 to 1,090 fps, all had supersonic "crack" at my elevation above sea level.

7.3 Little Gun
1,053 to 1,120 fps, all supersonic

I could not find the sweet spot of 1,000-1,025 fps with Little Gun and a 150 gr bullet. 7.1 gr at 980 fps was about the best I could do.

Next batch were with 125 gr Nosler Ballistic tip, Spitzer
5.9 Trail Boss
1,020 to 1,050 fps
all were subsonic

Next batch were 125 gr Sierra HP match king (2121)
6.2 gr Trail Boss
1,063 to 1,084
some had supersonic "crack"

Next batch were 110 gr Speer Hot-Cor SP
5.6 Trail Boss
1,010 to 1,054 fps
About 10% had supersonic "crack"
