Whatever you do - DO NOT REST THE BARREL ON THE SANDBAG!Davis said:I get that he wasnt using magnification so 50yrs the groupings can be off but the guy had a sandbag. As I read on in the article he had the same perofrmance with the .223 at 100 yards. Using a 1moa sight with no magnification can explain the difference in an inch but the use of a sandbag should mitigate that. Now I have to go to an outdoor range and test it myself at 50yrds. I have found that I get more accurate shots if I line up the tartget then pull the trigger about 1/2 way and then hold still stop breathing and pull the rest of the way. The long trigger pull of the PS90 could be effecting his shooting - But I'd be embarrassed if I could only get 2" average from any system using a sandbag. Also a professional shooter should account for trigger pull.
I found myself starting the shot with the trigger half pulled as well.Davis said:I have found that I get more accurate shots if I line up the tartget then pull the trigger about 1/2 way and then hold still stop breathing and pull the rest of the way.
I have loaded and fired a couple of hundred 55 grain FMJs and fired them through my PS90. I did not have an opportunity to seriously fire them for group, but beverage cans at 50 to 60 meters were in danger while firing offhand. I hit most of the time, and when I missed, it always felt like it was my fault.GlockandRoll said:Has anybody tried hand loading a .223 55 grain bullet in 5.7x28 brass and testing the accuracy?
I think at 1030fps from a 10.5" barrel that it will stablize, but not sure due to the TAC-16 I will put on it.
I just read a magazine article this evening with a review of the round and the 2 guns that shoot it. It showed stats that put it in the 9mm damage range.GlockandRoll said:I wound worry about that, it's nearly the same wound potential as a .22mag.. . at least that is what PS90 shooters I know tell me as the cant get the real ammo the gun was designed for.
