Permission to open a new thread on issues involving .22 LR firearms and ammo. Was in the range today. Use the Walther P22 and and the Remington 597 semi-auto rifle (also used the Glock 21 - no problems there - galing ng Glock talaga). Used 3 sets of ammo: 1] Remington Thunderbolt (lead - High Vel) 2] Armscor (lead - Standard Velocity) 3] Armscor (subsonic JHP) The Remington ammo KB'd twice on the Remington Rifle. After about 100 rounds of Remington ammo on the P22, my shots started slewing around (balagbag). The barrel was really fouled with lead. Using the Armscor lead SV on the Remington 597 resulted in groupings that are 5 inches from 50 meters. When I used the Armscor subsonic JHP on the Remington 597, I managed to hit the bullseye (about the size of a one peso coin) thrice from 50 meters (one hole yung isa). Then I started targeting the silhouettes from 50 meters. No misses (there were at least seven). This was after I removed the flash hider. When the flash hider was connected, I can only manage 5 inch groupings. I noticed that whenever the suppressor was also connected, accuracy suffered somewhat. Lessons learned: 1] Do not use the Remington Thunderbolt for both firearms; 2] Do not use the Armscor lead - Standard Vel for both firearms; 3] Use the .22 LR Armscor SS-JHP at least for the Remington 597; 4] Remove the flash hider for greater accuracy; 5] Remove the silencer for increased accuracy; 6] Always clean the chamber and barrel (especially the one of the Remington 597 - it looks polygonal).
