243 win

[corbin9191]

I am wondering if anyone has any load data for a 243 using a 65 grain hornady v-max bullet with imr 4831, because I went to the imr website for the data but they didnt have it. Thanks

Howdy.
The speer#12 manual has for a 70 grain bullet IMR 4831 starting at 45gr and max at 49 gr.

The Nosler # 3 manual has for a 70 grain bullet IMR 4831 startig at 46 gr
and max at 50gr.
Didn't see any info for a 65 grainer and IMR 4831.

IMR4831 will be too slow a burn rate for the light weight bullets. IMR 4895
will be better suited.
FWIW, 39.0 grs IMR4895 with a 70 gr bullet shot well under MOA in 7-8 different rifles. It was the "club" load.
I would look at IMR4895 with the 65 gr V MAx.

I am shooting some 100gr bullets with 43.5grs H4831SC and so far have only shot a 5group of .875 @100yds. I am going to back off to 43.0 grains and try another 100yds 5 shot group and see if this will tighten the group up a little.
If that doesn't work I am going to drop to 95gr Nosler's. Does anyone recommend a good load for this bullet. I am going for less that a .500 group with 5shots a 100yds. When I get there this will be the load for my .243 Model 700Remington.

65 v max in the hornady book 7 varget max 41.7 I would start at 36.5, h 4895 max 38.4, IMR 4064 max 41.2.

I would try either the 70 grain or 80 grain Nosler B tips with varget I shoot 80 grain Bal tips with 37.5 varget in nosler brass with WLR primers and it shoots fine and dandy under 1" at 200 yards. speed is 3090 FPS with a 26" barrel.

blkbear,

What primers are you using? Are you seating the bullet out further towards the lands? Give us a little more info on your combo.... you don't have much further to go to get to where you want to be.....

blkbear,

What primers are you using? Are you seating the bullet out further towards the lands? Give us a little more info on your combo.... you don't have much further to go to get to where you want to be.....

The primers that I am using are the CCI 200 large rifle and the bullet are being seated at 2.710 inches. That is what my LEE reloading books says.
