Much like the OP, temperature extremes made me try H4350. With the 75-grain VMAX, 46.5 grains gets me 3,490 fps (26" barrel) and .47" 100-yard groups for 5 shots. This is near maximum, so approach with caution.
44.0 grains of 15 year old AA2700 (which many sources claim to be the same as H414 and W760, at least for current lots) churns out 3,445 fps and the same groups as H4350.

Hi I would just like to point out that this powder (N140) is a good option. I always get a similar result for many 243 cal rifle and have used it for over 20 years always one powder always same case and primers I use this mainly for hunting but have a fun of shooting that tight grubb too

have a nice day. take care

Here is a site that has loads reported by shooters, always check a loading manual to verify that the shooter has not entered a typing error on the load that he has entered.
