[QUOTE="FAL Shot, post: 470261, member: 27328"] In .224 caliber, the 75-grain Scirocco II has a much longer bearing surface than the 60-grain Partition. Have not shot 62-grain Barnes Triple-Shok X yet. In my CZ 527 Kevlar Varmint 24" heavy barrel with 9" twist, the Scirocco II has been stable if shoved hard with a hot load (23.1 grains IMR 4895, seated .050 off the lands). In a 15 MPH crosswind it achieved a 1.2" group at 200 yards. Accurate enough for me. Completely stable at temp of 40F at 3000 feet altitude. I had one keyhole shot one day at -6F, but from a dirty bore and 22.7-grain powder load. The previous 9 shots were stable with even less powder. I did not test the Nosler Partition against the Scirocco II that day, as I was working up a Scirocco II load only. But I do know for sure based on my 100-yard test of the Partition that it would not have grouped as well as the Scirocco II. The Partition load is for whitetails in brush at closer ranges. It has nowhere near the BC or SD of the Scirocco II. I wouldn't shoot more than 10 shots of Scirocco without cleaning my bore, and I have gone to a 6-shot cleaning schedule as groups will be opening up by 10 shots, per many observations besides my own. 6 shots is twice as many shots as you should ever see in a day of deer or antelope hunting. Plan on using this load on mule deer, whitetail and possibly antelope this next season. I might be getting a custom .224 Clark by then, and the Scirocco II is at the top of the list for bullets to try, as well as Barnes X bullets. The .308 Win with Ballistic Tips just ruins too much meat and is way overkill for young deer and antelope of good eating age. Using M-Pro 7 LPX oil and M-Pro 7 gun cleaner reduces copper fouling and makes it much easier to get out than any of the old fashioned bore cleaners and Lubes. Throw the Hoppes 9 garbage in the trash if using Scirocco bullets. [/QUOTE]
