Re: new to the forum
Stick with what you've got. Your load sounds just right or very close to ideal for your rifle.
Before you replace anything (i.e., stock, etc.) make sure you actually have a problem that needs to be fixed.
Most stocks, etc. work fine for the majority of shooters, and small mods (like cheek rest pads, or slip-on buttpads to add LOP length)) can resolve most ergonomics issues for those who need tweaks.
Generally, newer shooters do best with very generic gear. It usually takes some time before they can acquire the skills to fully utilize what they have, and to figure out what will actually help them progress; it's not a cut and dried process.
I think that most shooters would benefit from a good, basic .22LR trainer. Something simple and foolproof, that will provide basic reliability and acceptably consistent accuracy. Start simple and cheap, upgrade only when it's clear the present setup is holding you back. The .22LR takes the workload, wear and tear off the .308, is cheaper to keep fed, and reduces shooter fatigue from repetitive recoil. The .308 is not a basher, but all recoil adds up, bigger or smaller.
Welcome and best fortune; and remember, it's your score that's important, not the next guy's. If you're making progress, there isn't any problem.
