Has anyone tried using lighter 308 rounds out at distance? I realize that 168gr and 175gr are the go to, but I am wondering if anyone has had positive results at range with say a 150gr or 125gr?

Join the contest SubscribeThose are some great results. I am just running a 20" barrel right now though, so I am not sure if I can get close to that speed. I am considering a longer barrel when it is time to replace the current one.If you can get enough speed, you'llv be surprised by the performance. I shoot 155 hybrids and Sierra 2156's at around 3030, and they are both just great at 1000. They go transonic at right around 1200 yards in my part of the country, which is around 900' elevation. The attached target was shot with Hybrids last Saturday morning. Temp was 28º, with left wind varying from 2.75 to 4 minutes. I lost one out the left in a let-off, but kept the rest reasonably centered, and elevation was pretty good considering I was freezing my ass.
Thank you for the reference. That sounds like an interesting option based on Frank's results. I am going to see if that is something I can get up here in Canada.Don't know why I didn't think about this sooner, but it is possible to make a more typically configured .308 perform better with (somewhat) lighter bullets - if you want to spend the money to do it. The Warner Flatline solids in 155 and 160 gr weights can make your gun shoot more like a 6.5 Cr, but they'll cost you more than $1.00 a pop.
Lowlight posted about the 160gr Flatlines here.
Palma shooters use 155 gr bullets because they are required to, not because they want to.
800-1000 yard us the big bullets drift less.
Thanks for the advice. I am currently working on load development with the 175gr SMK, but think I will try some of the 190's. Looks like it is about as heavy I can go without going to a 1:10 twist rate or faster.Shorter barrel, bigger bullets lose less performance.

190 SMK / NCC from a 20” barrel bolt gun does really well for 800-1000 yd use.
True, I was thinking International but mentioned USA. My bad.That’s a common misconception, but there are actually no bullet weight limits in US Palma. ICFRA-sanctioned competitions and some foreign countries limit weight, but we don’t here. Most of us actually do shoot them because we want to. Modern 155’s are not like the offerings from the old days, and they actually match up pretty well against heavier bullets when comparing them at real-world speeds. Also, the lighter recoil makes them a lot more manageable when shooting from a sling for a whole day/weekend or more.
I have a Lehigh load in a 26" running 3035 with CFE and 2990 with RL15. I find them better in the wind than everything below the 195TMK and they hold vertical extremely well. I can push them faster but these are the speeds they shoot extremely well at for the charges.
BC works out to .522 to line up for me. They shoot well I've shot about 100 of these in the last 2 months. Recoil is less they are fast to target and you can tell they are your bullets on steel
150 match.Which lehigh projectile?
