Hi guys, still have'nt tried R17 or 22, however, as i hav commented in another 270 wsm post about th effects of the 150gr NABLR on a medium sz deer neck shot i hav just shot another at longer ranges. Medium sz stag, just behind shoulder, round dropped him, however, fragmented/ exploded, internal damage to drop him but still alive, he would hav eventual died (30 -45 min lata), so finished him off agan. 1st shot 525m behind shoulder, after a couple stumbles etc then sat down, 2nd shot 470m to finish him off, neck, lights out. I will hav to try on larger deer to more effects/ energy/ kill at th longer ranges to be satisfied. Accuracy not a problem, where i aimed, i hit. My goal is to archieve a 700- 800m kill on medium (sika) to larger (red) deer.
