Are there any problems with soldering bullets sideways?

Sweet. Most of the bullets I have (5.5mm) already have a ~2-3mm hole at right angles to the main hole for wire to pass through, so just fill the cup with solder (piece of wood with some holes drilled in it makes a handy jig to hold them steady), feed in the pre-tinned wire, allow the solder to harden, and hey-presto. Use good quailty silver solder or lead-free solder for best results & least resistance. :)
