Folks I'm wondering if anyone is using the above powders in .243 Winchester 10 twist rifles.
I'm looking to load 65 grain Vmax and 70 grain Varmagdedon & Ballistic Tip bullets. Rifle is a Ruger No.1a
Glass bedded with a 2.5X10X40-5HD scope, Penrod Precision did all the work along with trigger work.
Thank you in advance for your time, help and consideration.
Have a nice weekend.
Semper Fidelis,

I no longer own a #1 in 243 but I've owned a couple in that cartridge. No longer have the data but I know I would have used both H4350 and 4064. If for no other reason I have a stable of #1 and with the exception of the 375 they all will shoot one of those two well.
I've never had too much luck trying to push a number one unless I've gone through the process of making them shoot, I believe it's the barrel harmonics and spring hanger. Reads as if you have remedied that. You might try 6.5 stay or Reloader 17 if you can find it.
 
I don't load any of this . I did play on quickload with them . they all look to be decent choices for powder / bullet combos . the case fills are good at max loads ,I like to work in the 95%- 105% case fill . these powders give good velocities . here is what I saw .

70 gr varm bullet .

powder ......................... max load case fill ................................ velocity
acc 2700 ......................95% ............................................................3300
acc 4350 .....................100% ...........................................................3480
acc 4064.........................93%............................................................3380

the top velocity of any powder was 3540FPS


65 V-Max

powder ..............................................max load case fill ....................................velocity
acc 2700.............................................95% ................................................................3388
acc 4350 .............................................101%..............................................................3529
acc 4064................................................95%...............................................................3480


the top velocity of any powder was 3630FPS
 
Lightest bullet I have for 243win is 75v-max, but haven't done any handloading yet due too needing to have it throated longer. Factory Winchester ammo 100pp jams into the lands (not by much tho).
 
I haven't used the .243 in years and I have two rifles chambered to te round. My heavy use of the .243 was when I lived in Nevada and gave jackrabbits and coyotes a bad time. I moved from Nevada due to a job transfer in 1979 and I doubt I've shot either rifle more than a couple of times since the move. Just got busy with too many other rifles. I don't remember the loads but I ran the 85 gr. Sierra game King hollow point and Hornady 100 gr. Spitzer over W760 with apparently good speed (No chronograph back then) and excellent accuracy.
That was during a time frame when I refused to use stick powders like 4350 and 4831 as I would have to dump, trickle and weigh each charge. W760 metered very nicely so I used ball type powders. I went back to stick powder only after buying an RCBS Chargemaster.
