I've got a 25" barrel 1:7 twist I'm looking to load the dtacs with.  I tried H4350 today and had a node around 41.5 but it was small, .3 on either side opened up.  I thought about trying H4831 as I have plenty of room in the case for a few extra grains without compression.  Anybody ever use 4831sc and a 115 in a straight 243?  What would be a good place to start?
