So after my last rainy Outlaw Rimfire PRS match I disassembled and re-assembled my CZ 457 XRS. The only changes I made was the torque value of the chassis bolts from 30 in/lb to 35 in/lb and a new thread protector I made.
I wanted to try out the Eley Match but my supplier only has the Eley/Remington Match in-stock and assured me it's the same stuff but with Remington's name printed on the package so I purchased a brick to give it a try and made sure he has at least 5000 round of the same LOT# in-stock if the range results are good.
The florescent dots are 0.5"
July 23, 2021 @ 8:00 pm till I couldn't see my targets and the wind conditions was perfect... calm, no breeze at all. Disregard the Tuna Can test targets. Test for group size, slow and controlled, no Tuna Can, just the thread protector. Eley/Remington Match Average - 0.363"
July 24, 2021 @ 7:00 am the conditions was perfect for my Tuna Can testing but come 9:00 am the wind conditions started to pick up and in came the rain and remained that way for the rest of the day. I need to do more testing and create a graph.
July 25, 2021 @ 6:30 am the conditions was good with a slight breeze. This LOT# CCI SV in the dark blue box surprised me. Disregard the Tuna Can test targets. Test for group size, slow and controlled, no Tuna Can, just the thread protector: Average - 0.349"
So... is it worth the extra cost for this lot # Eley/Remington Match??? The Eley/Remington Match will cost $1689.40 for 5000 rds with an average groups size of 0.363". I bought 5000 rds of these CCI SV in the dark blue box for $610.18 with a average group size of 0.349". For sure I will be saving this LOT of CCI SV for my future Rimfire PRS matches and it looks like I can shoot them without the Tuna Can.
Next week is the long weekend and if all goes well with my schedule I will be testing my other LOT of CCI SV in the new light bluish and orange packaging. I don't recall ever getting results like this from my past LOT of CCI SV. Did I get lucky with this LOT of CCI SV? Was it the new higher chassis bolt torque value or is it the result from the new thread protector and the barrel harmonics is now perfect? Many questions to answer and more testing to be conducted but with a group size average of 0.349" I'll will skip further testing and save the remaining 4000 rds for future PRS matches. However, I will have to do a few test groups at 100 yards to see how they perform.
