Curious to hear about your most accurate big bore setup. How tight are the groups and what efforts, adjustments, and testing were required to get there? Any tips or tricks for improving accuracy? Any tips for what NOT to do?
The only things I have physically done,1 polished the barrel and 2, take some off the lead to the trigger and polished it so there is no creep. No 2 barrels are the same so you have to slug the barrel,
- How to Slug a Barrel:
- Choose a soft, lead slug slightly larger than the bore diameter.
- Lubricate the slug (e.g., with oil or bore paste).
- Insert it into the chamber and gently tap it through the barrel using a cleaning rod.
- Observe the impressions left on the slug.
Remember, slugging provides valuable insights into your barrel’s rifling, ensuring optimal performance and accuracy. Need a chronograph, once i get 3 shots on paper(providing you have zeroed) at 100 yards, I just keep Lessing the psi until the group starts to tightens up, having an external regulator with a gauge so you know what pressure you have as you lesson the psi for the slug. 98% of the time i shoot and hunt tethered. Last but not least, breathing pattern. That day when i had 3 shots in one hole, there was no wind and i have not able to repeat it,lol,, I'm happy with 3 slugs in a 2-inch group at 100 yard for a hunting pcp big bore.
