OOScot, I would use 85gr Barnes TSX's on top of Varget for California and 105gr Berger VLD's on top of H4350 for the rest of the world. Try to use Wolf primers if possible.
Use the ladder method for finding the best group. For boattail (BT) bullets if you can shoot 200 to 300 yards is best. BT bullets take a few hundred yards to settle in. 1MOA is fine for coyote and larger game. If you must have Sub MOA groups then you will most likely suffer muzzle velocity loss therefore, impact energy.
If you have a chronograph use it. If you don't get a Chrony today!!! A chronograph is an indispensable tool when working up loads. There is more to accuracy than just group size. Extreme Spread and Standard Deviation will help you see how efficient your load is. Generally the smaller the Standard Deviation the more efficiently the load is working. Over a long period of time the lowest Standard Deviation will bare out the tights aggregate of groups.
And as for groups here's what I think, “3 is a triplet, 4 is a quartet and 5 is a GROUP.â€
Remember, once you have found the right load at the range, before you go hunting, go back to the range. Load up 50 rounds. Shoot 2 foulers, then ten rounds to recheck your zero. Don't worry, your new ten shoot group may spread out to 2 to 2.5 inches. You just want the bullets to all group around each other. Don't try to chase the bull. Just shoot at the exact same point for all ten shoots.
If they do all group around each other, clean your barrel as normal. Then while still at the range, return to the bench and shoot two more foulers, pack up everything and go hunting the following weekend. The 36 left over rounds should be plenty for any hunt.
PS I'm sure you all already knew all of this. I just wanted to give a little extra for the community.
glo,
Your joking of course aren't you??......your very first statement I agree with, the 85 grainTSX would make a good hunting bullet! The rest of your statement? I can't follow it or agree with it, 105's I am not going to reread this whole long thread but I thought this was a .243? A factory .243 is probably going to have a 1:10 twist, a 1:10 won't stabilize a 105VLD, you need a 1:8 and in all my 6brx and Dashers the 105 vld's shoot bug holes at 100 yards and under .7 MOA at 1000 yards. 12 shots out of a little pencil barreled hunting rifle? I have never heard of anyone doing that, 5 shots isn't even necessary in a hunting rifle, I myself would be more interested in consistent cold bore shots as I generally don't warm my barrel up prior to shooting a deer, were all entitled to our opinions and this is mine.

No, joking around here. I corrected the hunting bullets and powder to reflect .243 Winchester. I must have had 6mm BR on the brain when I posted the bullets and powders.
By the why, my wife shoots little bug hole 10 shoot groups with her factory, 2009, Remington 700 SPS Stainless Steel, hunting rifle. The load is mixed brass prepped and neck turned, WLR primers, 40.0gr H414 and 95gr Berger VLDs, MV 2954fps. I've shoot the rifle in prone 1000yd and get about 1.5 MOA from the same load.
I use the above method for pre-hunting trips (haven't been for some years do to my health) when using mass produces, noddle barrel hunting rifles. Most of us here at 6mm BR are accomplished hunters and shooters with excellent equipment. Because the Shooting arms manufactures are using more CNC machinery, their barrels are better and the bullets are better, today’s mass produced firearm is light years more accurate then those produces even 15 years ago. My wife’s factory M700 is a testament to that.
Now having said that, I shoot a 10 shoot group before a hunt to check two things. One, are my reloads and rifle in in good working order. Are they ready to be bouncing around on my back for hours as I trek through the hunting area. Two, am I ready to to go hunting or am I so excited that I am pulling fliers left and right, up and down. Remember, it just 10 stupid shoots to the same spot on the target from the bench. Set up time will take longer than to shoot the 10 shoots.
These 10 shots will also thoroughly dirty my barrel so that I clean it as usual. No extra work so the barrel is pretty and sparkling clean with lots of oil inside for protection. I can guaranty any of my factory rifles will print high and to the right by 2 to 3 MOA on the first cold bore shot. No, I want a fouled barrel for my first cold bore shoot.
I hope that clarifies my method of madness.
