Since people are driving the DTAC 115s @ 3200fps using RL-17 in a 6XC case is there any real reason for the other case sizes ?
</div></div>Huh? 3200 out of an XC? </div></div>

From the above mentioned article by German Salazar
"Reloder 17 Shoots 600-39X in First Match at 500 Yards
On July 20, 2008 shooting his 6XC at the Phoenix Rod & Gun Club, the author confirmed that RL17 can deliver real-world, match-winning accuracy. Shooting a 500-yard prone High Power match on the NRA MR65 target, using iron sights, German Salazar posted a very impressive 600-39X score. The three relays were shot with three different loads of RL17 in progressively “hotter” increments: 40.6 grains (3215 fps), 41.2 grains (3290 fps), and 41.8 grains (3311 fps). He shot 200-14X with the low load, 200-15X with the middle load, and 200-10X with the hottest load. German felt the middle load was the most consistent. (NOTE: these loads are all with moly-coated bullets–you should reduce the load by at least one full grain for “naked” bullets”.)
German explains: “Ask any high power shooter and he’ll tell you 600-39X is quite an achievement with iron sights on the new (smaller) MR65 target at 500 yards. I can say with assurance now that this powder will shoot accurately in the 6XC. Last week, using H4831sc, shooting the same 6XC rifle, at the same range, with the same course of fire, I shot a 598-29x. I do think Reloder 17 helped me shoot a higher score this week, with 10 more Xs. The extra velocity afforded by RL17 reduces wind drift considerably, and the elevation held very consistent, particularly with the first two loads.” Even at the hottest load, 41.8 grains (3311 fps) of RL17, German did not observe sticky bolt lift or other notable signs of pressure. So far, then, what we’ve learned about Reloder 17 is “all good” — in the appropriate cartridge, it will boost velocities dramatically, and it can deliver competitive accuracy in High Power competition."
