75 Vmax loads - 243 WIN

[Quackaddict]

Hey guys, want to post a picture and see what you guys think, I have a 243 I am doing load development for, it has a rem factory barrel and action (for now)

Load info

Lapua Brass
CCI Lg Primer
IMR 4064
Hornaday 75 VMax
COAL length of 2.260 (measured with a comparator)

Starting at the Bottom left and going clockwise ending with the center, 41.0, 41.5, 42.0, 42.3, 42.6

42.0 is listed book max, I am gonna go up in .2 increments until I hit pressure.

Who has done work with the Vmax bullets? I have them .015 off the lands. When I find the best looking powder charge I will adjust that, what has everyone else been doing with Vmax bullets?

P.S. I shoot three shot groups because of barrel heat and barrel life.

your top right group seems to be the best even with the flyer...all the other groups are pretty consistent

i semm to get better results with imr 4895

Here are some of my targets with Hornady 75gr HP's. The V-max shoots pretty much the same in my rifle.

My rifle likes H4831 SC. You might try it also.

I will if these dont show promise, I have been working trying to find that perfect bughole load but this rifle is proving to not wanna shoot anything other than about .75 MOA, this is with 3 powders and 3 bullets and various combos of them....
