You can do whatever you want, but remember at the end of the day your head is right behind the bcg of a ar, and if it goes bad well you get a extra hole in the head. As a nra reloading instructor I always recommend accuracy over speed. As long as the bullet getts to the same place every time you pull the trigger then you can adjust your sights

My goal was balancing accuracy and velocity. For my barrel/rifle I have found 18.8grs H110 with the bullet seated to approx. the middle of the cannelure gives me decent accuracy and velocity of approx. 2225. My cases are trimmed to 1.362 (+/- .003) and I use Wolf Small Rifle magnum primers.

Using a ballistics calculator shows this load is just above 1700 fps at 200 yds.
That is so weird because Im getting more velocity out of my 10.5 inch barrel using same powder charge..... I wonder why?!
1. Chronograph Differences... They all have their variances.
2. You have a tighter chamber causing higher pressure with the same load?
