How can comic artists visually represent the different types of gunshots (e.g., pistol, rifle, shotgun)?

Artists differentiate gunshots visually using the size and shape of the onomatopoeia. A pistol might be represented with a smaller, sharper 'TAP' or 'KLAK'. A rifle could use a longer, more drawn-out sound like 'RATATAT' or 'BRRRR'. A shotgun might be represented by a wider burst of sound, using variations like 'BLAM' with radiating lines extending outwards, signifying the spread of pellets.
