High Pressure! |
Hi Hunters, a cautionary tale. I live and hunt here in England and have reloaded for my 25-06 and now 6.5-06 for the last ten years. The rifle is a Sako TRG-S action which now has a Krieger stainless 26 inch barrel chambered 6.5-06. My sporting rifle has never had commercial ammunition through it, even when it was a 25-06; (I had it re-barrelled as a 6.5 two years ago). I chose 6.5-06 for the available bullet selection.
Hunting in England for small deer I could use a 120 grain Sierra, for instance, and in Scotland I use the 140 grain Game King for the much larger Red Deer. I have also used Speer, Nosler and Hornady bullets very successfully. Seeking to reduce the powder load for use on the smaller species, (we have Roe, Muntjac and Chinese Water deer), I reduced my powder load, Viht N160, down to 45 grains and filled the rest of the case to the base of the neck with coarse semolina. I have a photo which shows the result on the first shot, with a normal case for comparison. The bolt had to be hammered open!
I am grateful for the strength of a Sako three lug action and very embarrassed by the incident, as I must have loaded several thousand rounds, target and hunting, with no problems. The photo shows major brass flow into the extractor slot, a popped primer and a distorted primer pocket. When I have worked out how, I will send the photo. The ridiculous thing is that 45 or 46 grains of Viht N160 drives a Sierra 120 grain soft point very accurately at about 2700 fps, a sensible load by any standards. Moral:- Don't mess with something that works!
Best wishes to all for 2006,
