If you have IMR 4064 try it in the 243. Do not use mixed cases I found winchester cases worked best for me or Norma.

Now my last outing with the .243 I used 100gr Sierra #1540 with 40 gr H4350 Fully prepped winchester cases .241" ID no crimp, 210M primers.
2.640" OAL was where my gun liked them.
First cold bore shot hit 1" smack dab above bullseye the other 2 shots went left group measured .800" center to center.
Mossberg 100 atr. Stiffened factory stock and tweaked trigger.

I have a pound of it that I been using to see if it will shoot better or as good as Varget out of my 243 and no luck so far.
I also shoot varget in my 243. It's been readily available and as accurate as anything I've tried. I remember when it was as hard to get as H4350 is now.

Ive gotten fantastic groups with 87gr Vmax and 36.5gr of Varget. Right around .25" 5 shot at 100. I just thought I would try H4350 to see if I could get that more consistently. I havent so far but Im not done.

I'm using the 85gr Sierra Game Kings and get similar. I believe in the mix, 243, varget and 80's grain bullets. I'm also amazed each year how well it works on deer.

I have never used this weight bullet before out of my 243 and I dont deer hunt with it but Im trying to get this thing perfect. What weight powder and what fps are you getting? And what primers?

I'll check my notes when I get home and let you know.

Cool. I was just curious. I didnt find any load data for my bullet and Varget so I started low and worked my way up. I dont have any pressure signs at that charge or a few steps over it yet.

I'm showing my most accurate hunting load at 36.5gr varget with avg speed of 2862 and low extreme spread.
