They used to preach that one should sight in rifles at 25 yards and that they would be on again somewhere down range depending on caliber. I like to "rough in" a rifle at 25 yards because they usually hot the paper at that range, and then move out to a longer range, again depending on what I am shooting. My 20 gauge smoothbore at 75 and rifles at 100 with the appropriate charge. First off is the fact that even a smoothbore will shoot very well at 25 yards. Desired accuracy and precision is determined by the range one uses the rifle. As I use the 25 at closer range a 25 yard sight in is fine, but my 58 gets sighted in at 75 yards and tested at longer ranges to see point of impact. MY 50 was sighted in at 100 yards, etc. I have seen some very interesting points of impact with a 25 yard sight in as a bit high or a bit off to the side is magnified at longer ranges. I sight in a group anyway, but also as you have mentioned with your 32, a load at 25 can really open up at 50 or longer range. My 50 can look pretty good with pyrodex or 777 at 25 yards. At 100 I could just as well shoot buckshot. One individual on another site was talking about testing cast bullets out of a microgroove barrel. When he mentioned 25 yard groups I stated my position. Some got upset but that individual shot up some loads to get cases and admitted that about everything he shot looked pretty good at 25 yards. In a small bore I would want my 32 performing at 50 yards and my 40 can look pretty good at 100 yards with the rifgt load. All my shooting goes back to my bulleye shooting experiences. One reason that for general target shooting I switched from a 32 to a 40 in that a light weight ball just does not consistantly hold up at longer ranges as well as a heavier one. For most small game, one has to know at what range can I hot the head, or for some of the larger varietys at what range will a body hit work.
A squirrel head is about as big as what a 50 cent piece?
