Just fired my BIL's Ruger 77 in 257 Roberts. His Grandson is going to deer hunt with it this fall and they asked me to load some ammo, and test it. I had a box of 100 gr Speer sp's that had a price tag on it of $6.76 marked down from $8,45. It has a 3x9 Tasco scope and off course the mounts were loose. I cleaned it completely, tightened everything (most screws were loose) and loaded three different loads with A4350. To make a long story short, 3 shots in .681 at 100 yards. Trigger pull is terrible, but will make a good deer killer. Just had to post, don't mean to bore you. Barlow
