My cast hunting load for my Vanguard .358 is 38.5-39 gr of h322. The bullet is the Lee 200gr .35 cal gc. They weigh 208+- These shot well with the 45/45/10, but now the last ones have been pc'd..Brass is old .358 Win and new Starline .. all sized and trimmed properly. At 50 long steps... it will put 3 bullets nearly touching but one shot-usually the first shot is off being high and just a little with the pc. I did some shooting with the bullets tumble lube but most of my shooting has been the pc'd. so I have come to notice this most with pc. At 150 steps the rifle still puts two out of 3 in a very close together centered...but one at least is high and over to the left. Adjustment is not a problem. This makes this load non usable for deer hunting. I have a wood stock as well as an early Bell & Carlson stock. Both have been had the action acra glassed. The wood normally will out shoot the fiberglass. But with either stock I have the same one shot out and away with the rest very close together... about an inch at the 150 long steps.. Neither stock touches passed the first few inches. This .358 is one I have had and shot a lot since the mid 70's. There is barrel wear. The barrel now likes 225 gr Sierra and 250 gr Speer the best. So I was happily surprised when it shot the cast bullet this well. Any thoughts? My first was bore wear... but the shooting makes me wonder.
