Excuse the delay, I left my phone(picutures) at mom's house on Christmas lol. Good news though is the 142's are beast mode! But they only had a high of 920fps. Not quite the 950fps I was looking for. However they grouped well. That super hammer spring you found may do the trick cause she is only using the 400psi per shot like Dan noted. I found I could get a good string at a higher pressure fill, but that didn't turn into good groups. For example I got this string -
FPSI - 4000
EPSI - 2800
1. 894 - 3600psi
2. 918 - 3200psi
3. 887 - 2800psi
But this shot one high and then grouped the next 3 shots(This seemed about the same as the .401 barrel. 1 shot high, then 2 grouping at a higher fill).
So I went to the trusty 3800psi fill and got these numbers -
FPSI - 3800
EPSI - 2300
But they grouped like this at 57yds!
Then here are a couple more 52yd groups at a 3800psi fill -
Then I was able to get a 100yd group with the 142s. As soon as I shot I knew I totally pulled the 2nd shot. Once seeing the target I was like wow. That would have been a decent group.
Had that good group with the .356 142s but the .357s were not bad either. I ordered more of the .357s.
For the 130grs I didn't shoot any groups. Just fiddled with numbers and blowing up pumpkins and water bottles!!! But I ordered some more of them as they seemed quite promising. They shot at 948-929-900 from a 3800psi fill. And I was able to get great numbers from a 4000psi fill. 920-952-924-886. However I have a feeling it will be like the 142s with one shot high and 3 grouping.
Then the 120grs were screamers like the 130s. I got a high of 977. I got this string at 3900 -
120gr - 3900FPSI
4 shots FSPI 3800 EPSI 2300
But the first shot was high with that fill pressure. 3800psi seemed too high as well. I dropped down to 3700psi and got this decent group at 57yds(Think I pulled that 3rd shot) -
Hoping the 130s group well. Guessing the 142 BT will do better at distance though. All in all the .357 conversion did net an extra shot. Looking to be 3 good and a decent follow up. Going out tomorrow to see if I can't get me a deer with the 142s. Will be nice and quiet from all this rain today.
Side note the fine folks at NSA are the bomb. Just received the 142 and 130 grainers. I ordered them Christmas eve!
