The closest example is under the Enfield P/1853, .577 Caplock entry. That weapon normally does 3d+2 pi+, and the SAPLE round does 3d+2 pi+ (same) with a 1d-2 [1d-1] cr ex follow-up. That round weighs 0.086lb, and the Spencer round weighs 0.073, and normally does 3d+2 pi+.

These are close enough that an SAPLE round for the slightly higher-tech Spencer probably does the same damage as for the Enfield. If you want an LE round that has more explosive, trim down the projectile damage, because the bullet gets lighter and thus penetrates worse, and add to the explosive damage. The overall damage probably gets worse - explosive bullets for small arms haven't been widely used - but remember that explosion within a living target do 3x damage (as per B415), but aren't reliable at TL5-6 (See SAPLE on High-Tech p169).
