93R17 .17 HMR Shoots Better Fouled?

[Turkeytider]

Anyone have any experience with shooting a 93R17 fouled vs. clean? Today at the range my last groups really tightened up. I`ve experienced good accuracy ( POA vs POI ) but precision has been lacking at 100 yards. I usually clean my guns after shooting sessions but I believe I`ll experiment and shoot this gun fouled next range session. Anyone with first hand experience?

i clean when the groups start to open or long term storage

It's nothing out of the ordinary for a firearm to shoot better "fouled" than from a cold/clean barrel.

Yup. Cleaned my 93R17 GV and it took 15 rounds to get it back to to normal ( about MOA at 100 yds).
