I got one of the Muzzle braked Savage replacement barrels fitted into a fiberglass stock ..Savage varmint tapers are huge!! This Adams & Bennett 243 winchester now sports a threaded end for a shrewd muzzle brake...Awesome noise it makes ..After a short break in ..I started firing some groups..Right off it showed some potential at 100yds...with a variety of bullets...I got three ragged looking 7/8's inch groups[edge to edge]..& one looks like I can still shoot...using the 87 gr hornady V-max bullet..IMR 4064 powder...Cleaned the barrel again & cooled it some I set after the 200 yd targets...got 4/5 into an inch & an eighth ...first shot was 2.1/4 inches right & low..opps..next two were touching right on the money..but I could not keep it there..last two were 3/4 inch low of that..some days...the 6mmbr gun faired somewhat better at 200 yds 3 touching then two high & right by 5/8's...I blame wind & operator failure...Anyway I'm at a loss for this new barrel & a 243 loading...I'd like to stick with the IMR 4064 powder & 87gr V-max bullet..I should do the ladder test [afew tenths of a grain eack way] & vary the seating depth...past that ANY IDEAS ??? mike in ct
can't drive 'em str8 every day...sigh...

mikeinct,
I'm using H4831 sc with 87 grn. Hornady V-Maxes in my .243 A.I. with great results on paper and chucks. H4831 is one of Hodgdon's Extreme Powders which is temperature tolerant. I don't see why it wouldn't work in your .243, at least give it a try. The 87 grn. V-Maxes will be my primary chuck bullet this summer and it drops chucks cold! My velocity is approx. 3500 ft/s. with < 1/2" groups at 200 meters.
