... for Nosler's 90-grain ballistic tip. I cannot find any data anywhere. There must be some out there someplace, or they wouldn't make the bullets, right? I was looking for Varget, but would settle for H4895, or any cylindrical powder. I don't hotrod, so I just need a safe starting point.
I don't have enough reloading experience to be comfortable using data for, say 87gr V-max, or some other bullet of similar weight. |

From Sierra Reloading Manual 5th ed.
.243 90 grain FMJBT C.O.A.L. 2.650" Varget 33.1 grains gives you 2700 FPS. Varget Max Load 34.4 gives you 2800 FPS. This is in a 22" barrel. 1: 9 1/8 twist Casing Trim to Length 2.035" Primer Fed. 210M YMMV If the 90 grain you are going to use is a boat tail, you are good to go. Probably ought to start your work up with 31 or 32 grain. By the way, I am working with the 87 Vmax and never did find any published data that one. |

Quoted:
Nosler has some load data on their web site. There's a link at the top of the page. I had already looked there, and they only list two loads: H380 and IMR something. CCW, I have Hodgdon's 6th edition manual, printed in 2003. It lists eleven powders for the 87gr V-max. Did you have a particular powder in mind? |

Try this link.
I have switched from Varget to H 4350 for the 90gr hpbt and get better results in my AR 10T that is chambered for 243 Win./ 24" barrel with 1-10 twist. They run at about 3,100 fps from my gun. |

Quoted:
I dug data out of a Nosler manual tonight if you're still interested. The 85 and 90 grain bullets are lumped together. I would be most appreciative. I need to invest in a new manual anyway. All I have are a Speer #13, 1998 and a Hornady 6th edition, 2003. |

I forgot to write down the issue number.
For .243 Win with 90 grain Nosler bullets. Load data from a Nosler manual: IMR 3031, min 32.0 grains, max 36.0 grains IMR 4895, min 33.0 gr, max 37.0 gr IMR 4064, min 33.0 gr, max 37.0 gr W760, min 38.0 gr, max 42.0 gr RL 19, min 39.5 gr, max 43.5 gr IMR 4350, min 39.5 gr, max 43.5 gr IMR 4831, 40.5 gr, max 44.5 gr –––––––––– This load is reported as the most accurate. |

I have had great groups sub moa @ 100yrds using imr 4831max load and 85 gr. bthp sierras . I may still have the data for the 87 vmax(.243) that i used however all caution should be used of course and work up to it. I'll check my load book. and edit my post when i find my info.
ETA: The load I used was 43 grns of IMR4831 with the 87grn. vmax. And i based it off of the speer spitzer 90 grn./imr4831 data and worked up to it(43 grns was max load for the 90grn).I would suggest if you try this to reduce and check for the obvious signs. this was shot out of a ruger mrk 2 target/varmint .243 24" barrel i believe. Don't have the rifle anymore  wish i did was a great shooter.

For the 87 grain Hornady VMax here is what I am working now:
.243 87 grain H-Vmax (weighs 88 grain here) C.O.A.L.: 2.664" Powder: Varget 34.0 grains Speed: 2804 FPS avg, chronographed 8 rounds No overpressure signs; Next stop 35.5 grain Varget This is in a relatively new 22" barrel bolt gun, 1: 9 1/4 twist Primer: Wolf LR RCBS full sized, new Remington Cases, no crimp. Casing trim: 2.040" I interpolated between 85 grain and 90 grain published data to start at 34.0 grain for the HVMax (actual wt. 88 grain). YMMV |
