I had always fancied a 22250 AI with a quick twist, but my rifle maker has issues with the AI.
He has suggested I look at several other cartridges.
6mm x47(not really interested in a 6)
All are supposed to be great.
At home in yorkshire our fields are big. Wind drift is the biggest cause of misses. Why I wanted to keep case capacity and go fast twist to stabalise VLD's etc.
Never thought of a .20 but the 50gr have a good B.C. so am tempted.
The rifle is a sako 75 action 3 so they will have to cycle and feed from that mag.
Must say i'm tempted to go 22250 again but with a quicker twist. I run magnums and burning powder does not bother me 1 jot and powder is bought through my company also.
All i want is those red Ba2tard2 dead the further the better.
suggestions please from anyone with experience of those cartridges.
