I think people aren’t replying through fear of loosing the advantage.
I have had the cartridge debate with Ronin and MJR several times trying to find the ideal trade off between recoil and wind cheating.
I shot a 6.5X47 Lapua Accuracy International AT with a Schmidt PM11 3-20X50 I was hand loading a 130gr Hornady 130gr ELD-M Over 37.5gr N150 for 2820fps and an SD of 6.2. I didn’t have time to develop the load and used the same one I had used for a previous rifle. Another competitor shot an Accuracy International AW in 6.5 creedmoor with a Schmidt scope he used factory Hornady 140gr ELD-M at 2680fps.
We both scored 93.
Its more about riflemanship than ballistics. One of the Irish lads was using a .308 and the calibre wasn’t what let him down.
6mm cartridge’s struggled to provide a visual feedback when looking for splash on misses. I used mine to adjust point of aim.
What is clear though is knowing whatever cartridge you shoot like the back down your hand will give you the advantage.
The only person I’m out there competing against is myself right now. Because when you make a stupid mistake like short stroking and having a fail to fire causing the mandatory 30 second wait until you can cycle the bolt again which causes a loss of vital points there is only one person to blame. Especially on a 140 second stage.
To respond to Ronin, long action isn’t seconds it’s the risk of poor fundamentals and a short stroke.
