Hello 41Rem,

In my .243Win. I do best with the Sierra 85gr HPBT and IMR4895 37.5grs. and get .625" (5 at 100yds.). I don't get that every time since the rifle has a 22" sporter barrel.
I also use that bullet in my Remington VLS in 6mm Rem. With
IMR4320 39.5grs., and it prints .8" It's a new rifle, and I suspect it will do much better with time since it has a 26" heavy barrel and weighs almost 10lbs. For pure accuracy the rifles both do better with the Sierra 70gr. HPBT. Both print in the .4's and .5's. Best wishes.

Just shot one of my better groups with this new 243. Put 5 rounds into .424" @ 100yards, 85 gr. Sierra HPGK seated at 2.65" (of course for you Cal, thats 67.31mm), load is 36.0 gr. IMR 4895 and a Federal 210 gold match primer. I can seat the 75 gr. V-max out to 2.710" with no problem, but due to the shape of the gameking at that length it will engrave into the rifleing, so I have to seat it back a bit. Think the barrel is starting to break in, 183 rounds so far
