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 cut the barrel to 18" and it did shoot tighter groups..But not tight enough. 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. 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. Now after shooting that 2.0gr load I found I do not need to resize my cases. The neck ID has not changed from the .306" it started with. Case length has not grown even .001" after 6 firings. Bonus for sure that the case only needs brushed out and wiped down and reload it. Here is a 5 shot group at 20 feet..Yea 20 feet in my garage Case was not resized for this group. Powder was dipped with the Lee .3cc dipper not weighed. Super simple. I will stretch it's legs to 50 or so as this load is for close in critters. Squirrel in a tree.
