Skout Everything Skout EVO and Epoch

Ok i shot a few pellets today and i am now out of JTS since my order has not arrived.
After a very long and tiresome clean of the barrel with a copper brush a little bit of roblar and balistol oil, these are the types of groups i am getting at 58 yards with little to medium wind on a makeshift bench.
I am finishing a proper bench to take to the range on Wednesday to continue my testing.
The targets are from olympic 10m air rifle shooting and their overall diameter is 4.5 cm or 1.78 inches.
It took over 100 pellets for the barrel to start grouping again after the clean and average speed was 975 fps.
I ran a dry bore snake throught it a few times after todays shoot.
Assuming i receive my pellets by Wednesday i will try all of your lower speed suggestions.
The only pellets i have left now are jsb jumbo monster exact 25.39 gr.
