i tested 5 different kinds of ammo i cam out with 2 clear winners the Remington hollow points came out most accurate but the CCI STINGER that i has fed and cycles extremely smoother then anything i have ever felt. there is actually a noticeable difference. and it seems o all shoot the same no highs or lows in the noise it makes. it would be the best round out of the 5 i tryed for shooting long range (100-150). this was not a controlled experiment this was semi rapid fire 10 rounds in about 10 seconds or less. gun used was Remington 597 distance of 25 yards forgot to mention the firearm was sighted in for the federals
right to left top to bottom Remington thunder bolt, federal re box, CCI stinger, Remington hollow point, and Winchester.
the arrow is the top sorry i took the pic sideways
