Wondering if trying to get it tighter with a factory rifle would be a waste. Any other load info would be great. I also have 95 grain berger vlds and 87 grain hornady varmint.
Any help would be great thanks
I have that same rifle if it's the Walnut stocked Ruger with a 22" blued Barrel , (but mine is rechambered to a .243 AI and accurized). That grouping is very good for a factory rifle and you's be hard pressed to find any thing better. I shoot 100g Sierra Game Kings out of mine at 3200 FPS using H414. Mine starts stringing up after 3 shots due to heat, It's very predictable.
Mine serves as a Kids hunting rifle and will do as shots are limited to about 100-200yds.
All of those bullets are great for accuracy, but expecting more accuracy is pointless.
