Lou Murdica Profile--Thoughts on Calibers and Competition
Shooting a Pierce-stocked, VIET-actioned rig chambered in 220 Russian, Lou Murdica posted the best Aggregate in the BR School's 5x5 afternoon HV Agg competition. Lou had small group (.167") in the initial Warm-Up Match, followed by two more groups in the ones. This was a very impressive performance, considering Lou was shooting the "wrong" cartridge, with pre-loaded ammo.
But Lou's fine shooting wasn't just a matter of luck. He's done a bunch of testing in his own tunnel and his records demonstrate that the 220 Russian can run with the 6mm PPC, and that pre-loading is not a handicap. Lou told us: "I feel the 220 Russian is one of the most accurate .22 cartridges there is. I will be using it at the Super Shoot and at the Nationals. Based on my tunnel testing, shooting group after group, I've shot way more small groups and impressive aggs with the 220 Russian than with any other cartridge."
Why then, aren't more competitors using the 220 Russian, we asked? Lou replied: "The downside is that the case does stretch. You have to trim the case every time you load. I do that with a Sinclair tool that indexes off the shoulder. I know some guys have experimented with a sharper shoulder angle to cure the stretch problem, but then you lose the advantage of the design. The case design is right as it is--the capacity is right. You can mess around with the 22 PPC .100" short, but you just end up with the same capacity after a lot of work."
Lou preloads his ammo at home, using a George Kelbly-made full-length bushing die. He trims the cases each time, then bumps the shoulder "just a tad" and neck-sizes with a .243" bushing. His match recipe is 25.0gr VV N133 with Fed 205 primers and Spencer FB bullets. "Don Spencer makes the 'ugly bullet'. A lot of guys on the West Coast have set records with his bullets," Lou explained.
The barrel is a 22.5", 4-groove Kreiger, chambered with a .246 neck for turned necks. The gold-hued action is really quite unique. It was produced in Germany by K.D. VIET, and Lou says it's the finest action he owns. That gold coating is not just for looks--it makes the action both very, very durable, yet incredibly slick. Lou showed us the inside of the action. Though thousands of rounds have cycled through it, there are virtually no signs of wear.
Given his success with the .220 Russian, would Lou recommend that caliber for new competitors? "No", Lou cautioned, "I'd say a new guy should start with a 6PPC. It is the most forgiving case. There are more components, and more good bullets in 6mm. Start with the 6PPC, get good at it first. Then, when you're ready to play, go to the Russian. And I'd suggest the Russian over the Walldog or 22 100-short. It's very hard to make good Walldog cases. And the 22 100-short is the same case capacity as the 220 Russian--so you're not really gaining anything. A 22 PPC has too much powder capacity I think."
