Jeff. Well I finally got my Blued low rings for my Ruger #1 from the importers, replacing the high stainless ones sent with the rifle. It cost me postage but what the hell. I have used Sierra 150 grn, sierra 180 Grn and Woodleigh 174 round nose projectiles with extremely good accuracy. I am seating the projectiles now 30 thou from the lands, which still leaves the bullet well seated in the case, even the 150s. I am using ADI 2209 (equivelant to H4350) and I can get 2800fps with the 150s comfortably, with groups around 1-1 1/4 inches which suits me. I have a Zeiss 2.5-8x33 on the rifle with an extended rear mount which gives me plenty of clearance and eye relief. I pushed a lead ball through the barrel and it measured .313 which I think is spot on for this caliber. Two other rugers in 303 owned by friends also shoot very well with 150 grain bullets. I can not fathom why people are having trouble with their ruger #1 in 303.

Underlever. You say you have only fire five shots from your rifle. IMHO 5 rounds is not much to base accuracy on, especially if they were only one brand. I ould like to hear the results of several different brands and weights fired.

I am very happy with mine as it is a great light carry rifle with plenty of punch for the local deer and plenty accurate.
