Help with bullet selection for new tikka in .243

[Zking]

I've been loading the 107 tmk. But It took a little tinkering to find a load I considered good enough for me ( I wanted 10 shots under an inch). It still wasnt bad though.

The 108 eldm is kinda the easy button on the heavier / higher BC end of things. They just shoot in almost every gun.

Depending where you are elevation, DA , weather & all that the 116 might be on the edge of what the 1:8 will do.

Yeah I’m at 4-600ft elevation here at home so -500 - 2,500 da depending on time of year
I think the 116 would probably be marginal

Is the 103 eldx similar in ease of loading to the 108 eldm?
