RE: handload Accuracy
Like the others said your degree of accuracy will depend on how many different loads you try in your part. gun.
Some guns like lighter loads while others like those high pressures. Try as many different powders and bullet sizes as you can and shoot for groups not accuracy. You can always move the sights after you get the group you want.
I hand load for all my guns (shotguns included) and have never found any factory load that will even come close to the groups I get with my handloads.
I go even farther and have two loads for each gun. My 22-250 for example will produce 5 shot groups you can lay a quarter over at 100 yards with 36 grains of 4064 and ballistic tip bullets but this powder does not go through my powder drop as well as some so if I am serious I must drop the load from the powder drop and then weigh it to check accuracy.
With 414 this gun will shoot 3/4 inch groups at 100 yards and this powder flows through powder drop great. So if I am loading to just target practice or praire dog hunt I will load with this powder and bulk bullets for ease and cheapness of bullets.
Coyotes get the ballistic tips!!!
