I have 2 of the Kahles MultiZero's, 1 of the the Zeiss Conquests with a RapidZ 800 reticle, another Kahles with the TDS reticle and a Burris Black Diamond with a Ballistic Mil Dot reticle.
I love my Kahles MultiZero's (probably because I got them each for $600.00 off gunbroker a couple of years ago). You can make them fit any caliber and load by setting the marks on the top turret. However, Kahles are more expensive and they have recently changed ownership. No one knows what their customer service and warranty policies will be like in the future. They have been a fine company and are the oldest scope manufacturer so everything will probably be good. As far as putting on a heavy recoiling rifle, I have one on a 338 RUM now but it has a heavy barrel, ported muzzle and 2 recoil compensators in the stock so it kicks like a 30-06. That scope has not created a problem yet, but at this time I think I would be in deep doo-doo if it did. Would probably have to go back to Europe and it would probably be awhile.
The TDS reticle would be a fine reticle if you can find one in your price range. I think the only new TDS reticles are on Swarovski's. However it would fit your trajectory well. You would have to do a lot of work to formulate your load to fit the reticle.
IMO the Zeiss Conquests with the RapidZ reticles are the best way to go. The Conquest's are excellent scopes with the best clarity. They are selling tons of new scopes here in the US and their customer service has been superb from all reports. With their RapidZ 600 reticle
shooting a 225 gr Accubond at 2800 fps zeroing at 200 yards the bars will be on at 298 yds, 393 yds, 498 yds and 600 yds if you set your power on 8.7 with a 3.5x10 scope or on 7.83 with a 3x9 scope (I don't know why they would be different but that is what the form says).
If you want to go up in power to a 4.5x14 the you would get the RapidZ 800 reticle
shooting the same bullet then the bars would be on at 294 yds, 396 yds, 497 yds, 600 yds, 704 yds and 808 yds when you set your scope on 10.61 power.
One thing I quickly learned when shooting at the longer ranges is that the ballistic reticles are much better than guessing at holdovers and that the higher the magnification the better your groups will be.
The Conquest 4.5x14x44 RapidZ 800 is my favorite scope and the clarity is amazing. I no longer break out my spotting scope for long range shooting at the range because if you can not see the holes through the scope then spotting scope (admittedly not a good one) will not be able to see them either. I have seen 22 caliber holes in white paper at 300 yards on a good day with the Zeiss. You can have a 4.5x14 Conquest for right at $750.00 or a little less by calling the on line shops like Large Selection of Discounted Scopes, Binoculars, Rangefinders and More!
, Quality optics and accessories from Leupold, Bushnell, Burris, Nikon and more!
or Cameras, Binoculars, Spotting Scopes, Rifle Scopes - Camera Land NY
even though they list higher.
The Burris is not in the same league as far as optical quality with the Zeiss or the Kahles. Their Ballistic Plex reticle would be close to your ballistics but again it will take some load development work to get it there.
I don't know about the Shepherd scope but it would be my guess that it would be at the end of the line.
