243 Ackley Load Data

[art123]

Looking for information on what powders work well in a 243 Ackley with bullets ranging from 55-75 grains as well as 95 grain bullets. I've tried some H4895 for the lighter bullets which seemed to work fairly well but heard that IMR4320 would give good results.

Art - I put together a 243 Ack last fall and it just plain assed shoots.
It puts 100 gr Sierra's or 55 gr Nosler's in almost the same hole.
These are loads I am using
45.0 gr RL-19 100 gr Sierra
48.0 gr H-380 55 gr Nosler
49.0 gr H-414 55 gr Nosler
My notes say the H-380 group was 1/4 to 3/8 in
and the H-414 was basically a one hole group
Try going to www.angelfire.com/nd/243ackleyimproved
There is a ton of information there.
Hope this helps
