So i have a Ruger .308 that does not shoot tight enough groups for me. The chamber is iffy. But it may be the perfect candidate for reduced loads with cast bullets. I have a 32-20 and I made a few bullets for it using the Lee 311-93-1R mold it gave me .311" diameter bullets at 104 gr with soft lead after powder coating them. I sized to .309" and loaded some into some neck turned and annealed Federal cases. https://leeprecision.com/mold-dc-311-93-1r.html Yes i neck turned them. I found with cast bullets neck turning really improves the groups. And I want to leave nothing on the table for this rifle. I decided to use red dot powder as it has proven very stable and accurate for me in very reduced loads. I started with 3.5 gr. That was quite loud.. not what i expected. Reduced to 3.0 gr. then 2.2 and then 2.0 and then 1.5 gr. The 1.5 gr load would still pass through 5/8" ply wood. and sink into a mulberry stump to the base of the bullet. Still a bit loud. I will head out to the range and test. This should be a real money saver as far as components go. I will stick with 2.0 gr load as that is what the Lee .3cc dipper throws. Keep it simple.
