That has not been my experience at all. I recorded sub 10 SD's over 50+ shot strings and sub .5" 5 shot groups. Every barrel is different so experience is going to vary but my experience with A2520 has been that it is the best I have tested thus far. Temperature sensitivity is the only downside but is easily mitigated by recording dope at different temperatures. I find A2520 very easy to work with and forgiving. A2520 goes with 6.5G like peanut butter and jelly.
