yeah, those .223 went in sideways though.
Not hardly. For 600 yards I use 80 gr. SMK's with my match AR. These are loaded long and must be loaded in the rifle one at a time as they won't fit the mag.
As for MT: Using ball ammo I would say you did pretty well. I use 168 or 175 gr. SMK's in my match tuned 308 M-1 to make those 600 yard shots. When the job situtation changes, may I suggest you may enjoy shooting High Power. Course of fire is:
Standing, 2 sighters and 20 rounds for record in 22 minutes at 200 yards.
Sitting, 2 sighters in 2 minutes, then from standing to sitting 10 rounds in 60 seconds with mag change. From standing to sitting a second string of 10 rounds is fired in 60 seconds for a total of 20 rounds for record at 200 yards.
Prone Rapid. 2 sighters in 2 minutes, then from standing to prone 10 rounds in 70 seconds with a mag change. A second string is fired from standing to prone as above for a total 20 rounds for record at 300 yards.
Prone Slow fire: 2 sighters and 20 rounds for record in 22 minutes at 600 yards.
Sight picture remains the same as the aiming black gets larger the further back you get. There are also 100 yard matches which are shot on reduced targets when a full course is not avalible.
Total number of round expended, 88 with 80 rounds for record. Some people get all wrapped up with thinking they might not shoot well enough. High Power shooters are some of the nicest people you will meet, always willing to help the new guy with the loan of equipment and advice. Few High Power shooters are stuck on themselves because we all started out about the same....at the bottom of the ranks. The match winner will have plenty of trigger time and managed to make the fewest mistakes during the match.
An Expert Marksman in the Service would about equal a High Power Sharpshooter.
