[QUOTE="SSTX, post: 1005382, member: 56302"] With so many suggestions that I single-load Bergers, I'll likely have to respect that advice and try it. For now, I shot some Accubonds and BT's this morning under marginal conditions (windy, 70-80 degree temps) but had some good results. The rifle eventually printed a 1/2" group with each bullet, the Accubonds over enough H4350 for 3240fps, and the BT's over enough H4831sc for 2980fps. No obvious signs of excessive pressure in either test string. This rifle, very much like a Shilen-barreled .25-06 I used to have, showed a dramatic preference for one particular propellant charge weight in a string of test loads. For instance, the groups 0.2/grain either side of the 1/2" groups were spread out at about 1.5". Running the numbers through an on-line ballistic calculator, it appears the Accubond carries slightly greater energy and a flatter trajectory at 600 yards than the Ballistic Tip does at it's preferred lower velocity. So, I'll work with the Accubond for now, and maybe do some single-loaded Berger experimentation when the weather here in NE Texas cools down enough for some serious range work. In the mean time, I've got some serious brass prep work to do before the next round of shooting............. [/QUOTE]
