Your question has been answered... barrel flex, steadier to hold and as I stated about MOST companies don't make a quality aftermarket thin barrel. You won,t shoot 200 yards accurately with a standard factory barrel. You need a good bull. I practice shooting long range first with my 22. Look up john burns he practices at 200 plus yards with a bull barrel 22 pistol with a packlite upper reciever . If your gonna punch paper at 50 yrds don't waste your money
