Thread: A Soggy Sarurday Put to Some Use

Greetings Again,
Today dawned with a steady drizzle so it is back out to the bench. An inventory of the loads on hand for the M700 .308 revealed an eclectic mix of geriatric loads, a bit like their owner really. They fell into two types, full power hunting loads and light target loads. The former were loaded as far back as 2009, their 6th load so the cases are old. Some have cracked on firing recently prior to me starting a regular annealing of cases and the decision was made to retire the loads for range use and load some fresh loads, in new cases for whatever hunting I may do with the rifle. The decision was also made to retire the dregs of my Dupont IMR4064 (packed 1979) and use fresh AR2206H for the Hunting loads. There weren't a lot of the light target loads left so it is just a matter of keeping up the supply. These are loaded with the 155 gr Frontier projectiles and 32 grains of AR2206H which chronographs around 1,900 fps. Shoots well if a little grubby so that will be that
A new load will be required for the hunting cartridge. Once again AR2206H will be used with the 150 grain Hornady Interlock. 44 grains was recently tested which gave 2,675 fps in my 20" barrel and 45 grains should deliver about 2,725 fps. In the distant past I worked up to 2,890 fps when the barrel was 2" longer so 45 and perhaps 45.5 grains, the last book max will be tried.
The Bergara is already sorted so that just leaves the SAUM and the rest of the old soldiers.
Regards Grandpamac.
