Weight Difference in CZ 550 Stock

Nice group, whats your load? There is a big difference between high 80 something grains and 100 grains of RL22. 105 grains of H4895 will get your attention, and is a time proven classic Rigby load.(Jack O'Connor strikes again) Past that and you're entering Weatherby country. My standard load is 98 grains of RL22 with a 400 grain TSX, A-Frame or Banded solid at 2350 fps. It outruns Federal Factory by 100 fps. I try to limit range sessions to 40 rounds. After that it isn't fun anymore. 35 is better because I can get to the range twice with a pound of powder.:D

I figured I'd keep it conservative to start and used 89.0 grains of Re22. According to my Hornady manual, that should be generating 2,100 fps. The max load listed for Re22 with the 400 grain Hornady RN is 99.1 grains for a velocity of 2,350 fps.

The maximum velocity for the 400 grain Hornady RN in that manual is 2,400 fps. If there's only another 300 fps to be gained between starter load and "max", my plan would be to work up to that as the shooting becomes more comfortable. :)
 
Conservative is good. Many people fire very few full power loads and do all their off-hand practicing with reduced loads. If you are happy with reduced velocities you can take a look at 5744. The recoil is like a .270.
 
Just the 350s but data is out there for the 400s as well. Cheap practice 350 grain Speers and cast bullets with reduced loads seem to go together better than $80 for 50 A-frames. I haven't shot a lot of these reduced loads since I'm actually working my way up to something like a Lott or perhaps a .450 Rigby. Since the .450 Rigby is more or less a .460 Weatherby without a belt it may be more interesting. Whether or not I actually make it there awaits to seen but this playing with big guns is a lot of fun. Taking them hunting where they were designed for is even more fun.
Is your Rigby on a Ruger? I should remember but don't.
 
When I had my Rigby I would load 100 grs of H-4350 behind a 350 gr X or the 350 gr Speer Magtip in Norma brass. I believe the velocity was around 2800, but this is going by memory; I do recall that it shot pretty flat. If I had one today I'd probably work more with 400 gr bullets and slow em up. Still, I shot this load well and could hold 3 rounds prone, but not 5, so I believe that was the limit of my recoil tolerance.

My .416 is in a CZ 550, the .375 is a CZ 602 (Neo's .375 H&H is a Ruger). The object of the exercise now will be to learn to shoot them (both) well, and then use them for what they were intended.

Since we aren't going to Zim 'till 2011, I figure I have some time to get used to them. I am quite pleased with the .416. It's great to have finally shot it.
