First and best of three 100 yard groups with 18" 3 groove tight rimfire Benchmark .22 barrel on FX Elite single shot rifle. 18.1 gr JSB un-weighed or rolled, 920 fps (probably too high).
Conditions were very good..
CTC = 0.75 inches 0.72 MOA.

Sorted and batched pellets at lower velocity may do better, but it's a start.
This barrel was previously owned and used and profiled for his FX Independence receiver by Dan Brown.
FX Elite with all its bits: Top to bottom: BSA .25 barrel; FX st .25 barrel; rifle with Benchmark .22 tight rimfire barrel and Chip Smith titanium 425 cc air tube for Benchmark barrel clearance; .22 FX ST barrel; skinny barrel for 300 gr projectiles; FX 500 cc air reservoir:
