HI ALL..JUST GOT BACK FROM MY CLUB RANGE....tested out new Rcbs Chrono...works fine....finally got to see what my loads are doin'
First was S&W M57 6" from 1965..load is new starline brass wwlp primer 17gr AAC #9 boolit is ballisi-cast #258 Keith 221gr in #2 alloy sized to .410"
10 shots: High 1410fps low 1322 avg 1366 es 88fps sd 32fps
good grief..no wonder the recoil is heavy....sharp wrist twisting recoil with a LOUD booming muzzle blast...but phenomally accurate....1/2' at 25yds..clean burn with little residue...
Next was Ruger Super Blackhawk stainless 5 1/2" bbl 2007 vintage...
Load #1: new starline brass wwlp primer 20gr. AAC#9 Boolit is Lyman 429421 235gr
hollow point #2 alloy sized to .431" from an ANCIENT mold KEITH bullet with deep square lube groove..
High 1496fps low 1439fps avg 1470fps es 57fps sd 23fps...WOW..smokin' fast load...from a 5 1/2" bbl...!!!! PLENTY RECOIL...sharp vicious muzzle blast...primers were round..no flattening..no unburned powder..clean load and accurate....1" at 25yds....
Load #2..Ruger again new starline brass..CCI 300primer 10gr. "NEW" Unique same bullet as above..
High 1235fps Low 1196fps Avg 1213fps ES 39fps SD 14 fps..!!!!!
Somewhat more milder load..more a top end 44Spl load but plenty fast enough for 50yd. Whitetail Huntin'..my self-imposed limit for handgun hunting...Am going to use THIS load in my 1975 vintage M29 8 3/8"...dont want to batter it to death..its already been to S&W for a rebuild once in 1978...
Load #3..new starline brass wwlp primer 20.5gr VN 110..same bullet as above...
High 1460fps Low 1391FPS Avg 1435FPS ES 69fps SD 24fps..
Another fine accurate full power heavy recoil load....
Actually I will probably use the unique load..its very pleasant to shoot all day and plenty powerful enough...I experienced NO LEADING...NONE....in either weapon.
Was very suprised by the high velocities from the 5 1/2" bbl Ruger...also it is VERY accurate...AND..am glad that these magnums ARE delivering what is promised...all the velocity one needs....Am torn between using the M57 or the Ruger...The M57 is THE MOST ACCURATE handgun I own...puts 5 shots into almost one hole with all 5 touching....it just shades the Ruger...but not by much..!!!!
