"The 225 gr is alright for smaller lighter animals. However, like you John I would like to see Rigby load to full potential and with 250 gr and 275 gr bullets. They could even load Pondoro Taylors preference the 300 gr bullet."

Further to my above statement. On other forums I see a growing number of people opting for and recommending light for calibre bullets. So, in the 358 they are looking for 180 grain and 200grain bullets.

These have a place. I have used 200 grain Hornady Spire points in my 35 Sambar MV 3000fps and a mono metal 185 grain MV 3190 fps. I only used these on pigs and would use on Camel (not hard to kill and soft) I would not use them on bigger tough animals. However, on Sambar, Russa and bigger I use 225 grain Woodleigh PP's or 250 grain Woodleigh's PP/RN.

The thing to remember is modern bullets are often better constructed than those in the past, so a lighter bullet at faster speed will still penetrate. To me this seems ok logic but what happens when that lighter bullet hits solid bone???

I still think heavier bullets are better for big and tough built animals. One reason being that they all expand about the same and the lighter bullet will pull up quicker and any petals that break off means the bullet loses a greater percentage of its mass. Yes, I have shot pigs with .22 rimfire and .223 but I do not consider them a cartridge for pigs.

The above are just my thoughts. Open to others' ideas on the subject.
