I have an old ruger #3 in 223 that I bought nearly 1000 Barnes varmint grenades for, going thru my oddment box I found a part box of hardcast 223 bullets, with copper gcs fitted and lubed with that blue lube. Sized at 0.225"
At some stage I'd tumbled them in alox and, as there were only about 65 left and I had a 100 cases primed and ready I looked up my 4th edition lyman cast bullet handbook and could see I could use 2400.
I loaded them up with 10.5 grns 2400 and headed for the 25 yard range to sight them in.
I spent the first half dozen chasing round the target trying to get the darn things to hit where I could see and eventually found they shot 8 inches low and 5 + inches to the right.
Group sze for the next 5 rounds was under an inch at 25 yards.
I thought the scope must be off so put 3 of my varmint grenades downrange, 3 overlapping holes, 1/2" low and central ( it's sighted for 3" high at 100 yards and point blank range is around 280 yards.
WTH is going on here.
Velocity of the cast bullets 1860 +/- 23 fps, velocity of the VGs 3340 fps.
Cast loads were very quiet and recoil free.
