Re: Remington 788
The 788 used to be a popular BR action, before the advent of the 6PPC. The BR guys shot mostly 222 in them, and had good success. When the 6PPC, 30 BR, 6BR etc became more popular, the 788 was found not to be able to handle the pressures, hence the development of many of the custom actions for that game today.
I had an old ( early 1970's ) 788, in 308. Wish I had it back, but lost it to a thief. Hope it blew up in his face....
Keep us posted on your project - I like these old things!
