Thanks Canuck! smile I was just thinking how I should ask some Maple Leafs how it works for them! ha I used R22 in a 300WM in Namibia...20 deg at night and 120 by noon, no issues I could tell. I shot the little Springbok and those big Gemsbok out to 375yds or so early/late and right around 11 AM. I shot four of each ( 1998). However, 61 gr in a 280 AI gave a very stiff bolt lift around 78 deg in Texas, it was perfect in Utah/WY...go figure? ha
