1: Your powder burnrate and weight of charge needs to be compatable with bullet weight.

2: Case preperation

3: The bullet


1: There are different types of powder from ball, extruded, long cut extruded, short cut extruded, spherical, flake, to name a few. All have different burn rates, different compaction, and volume size. In most cases the more volume the powder has in the case, the better the accuracy. the slower the burn rate is, the more pressure behind the bullet. Normally for heavier bullets slower burning powder is used. Keeping a constant amount of powder in each shell is the biggest factor.

2: The most important thing when it comes to case prep for accuracy is in the sizing process. Some neck sized only, some full length size depending on what weapon you shoot. The second most important thing in case prep would have to be trimming the length of the case along with chamfering and deburring the neck inside and out. Then primer pocket prep. next would have to be flash hole prep.

3: What effects the accuracy of the bullet most is the shape. long pointed bullets with boat tails are supposedly better for "cutting the wind". Flat based bullets with round noses are supposedly not as accurate. Then The weight of the bullet because the weight of the bullet determines how wind resistant it is. Then the hardness of the bullet. Harder bullets build more pressure because they don't shape in the barrel and go through it slower than a softer bullet. jacketed lead bullets seem to have the best accuracy because they form to the shape of the barrel when traveling through with less fouling to the barrel. Lastly how the bullet is seated in the case.

4: In my humble opinion, and this is only my opinion. You need to reload each and every gun differently to conform to the guns needs. Some guns shoot better with different powders, bullets ect...
