Some time back I posted about working up cast loads in the .257 Roberts Ackley Improved I bought.

.257 Roberts Ackley Improved.

At the time the results were very good but I felt I had topped out on the ability of the WW alloy so finally got round to casting in linotype to try.  I have a good stock of lino and have been 'saving' it but at the age of 55 I am thinking 'saving it for what?' so threw caution to the wind.

50m/55y preliminary testing this weekend produced good results.  Astounding actually.

113gr GC powder coated over 24gr H4895 for 1900fps.

86gr PB version powder coated over 11gr SR7625 for 1770fps.  6 shots of which the 2 to the right were my poor hold

Will push out to 100m/110y when time permits.  

 

Cheers from New Zealand

At age 68, I now say what the heck and buy the darn thing. Not a lot of time left to play with things!

I like H4895 powder. Good stuff

My stockpile of lino is down to less than 2 pounds. Don’t know what I am saving it for. 

At 71 I no longer buy green bananas. 

I did buy a new (used) toy this week, just because. Winchester M37 in 12 ga.
