I shot my first match at Roseburg. What a thrill I am hooked. Glock the plates was a total thrill shot 1 string at five secs with a G20 was happy with that. But I really sucked on the D1 targets My main problem besides trying to go to fast (had 4 misses) is the NRA D1 targets. I have a hard time telling where the so called X-ring is. I am use to shooting a bright orange dot on my targets. Any hints or advise on taking aim on the D1 targets especially at the 15 yards and beyond?
