I haven't tried the Scirocco...but I only have one deer rifle...1980 vintage Ruger in .243...If you want a "harder" bullet...I've had good success with the 100gr Remington Core Lokt....100 gr Federal Nosler Partition and the 100gr Hornady...all of these will give a good exit hole with a center lung shot...About 3 yrs ago I switched to the Federal 85gr BTHP where longer (over 200yd) shots might occur....I'd shoot whatever gives the best group...flintlock
