Looking at the Loopy specs, the fine lines on the TMR are 0.05 mils thick and PR-1 fine lines are 0.15 MOA. Meaning, on a 100 yard target the TMR would cover .180" while the PR-1 would cover .157", making the TMR the ever so slightly more bold reticle correct? I have a TMR 3.6-18 on order, hoping I don't regret going with the non-illuminated version. Never had anywhere close to an issue seeing the reticle in my SWFA at low light, though for comparison the thin lines on it are 0.07 mils thick, or .252" on a 100 yard target.
