Years ago in another country I shot Sika , Reds and Hybrids with the Hornady 60gr. softpoint and the Sierra 63gr. semi-pointed bullets fired from a Tikka Continental .22/250 rifle with a one-in- twelve twist .
I do not think these would be suitable for a .222 though.
Noslers own website states that in VARMINT WEIGHTS the bullet is constructed for INSTANTANEOUS , VIOLENT EXPANSION .
Irrespective of what your re-loading supplier may think this is not a bullet designed for the humane shooting of any Deer.
note the shot placement through the shoulder, these 2 were shot on the edge of a massive rape field, didnt want any runners which may have happened with a heart/lung shot. they dropped on the spot and died instantly. meat damage was minimal.
Hornady do 55 grain SP with or without a canalure that are spot on for fox and small deer using a 222. I push the ones with canalures at just shy of 3000 fps with Viht N130 and have used them to shoot day time foxes out to 275 yards but you need to have a good play at different ranges as the drop is quite rapid after 200 yds.
the best bit is they are cheap as chips from my RFD at £9.95 for a box of 100
However for the politically correct members of the site, Bruce Potts did an article for ST in 2010 which he researched best selection of .224 bullets for deer. He looked at both light bullets for standard twist and heavies for the tight twists (1:8) so its a good article. However I profoundly disagree wuth his reference bullet which was a 40 gn V max, which was inappropriate as it not even deer legal in Scotland (? 50 gn is mininimium). Also the ballistic effects on balistic material can not be compared to the chest of a roe, but that is a completely difrerent subject.
I have a copy and was reading it last night but for the life of me cannot remember the best bullet, but 65gn Sierra game king does come to mind.
