.243 powder

[lablover]

My father in law gave me a .243 a year ago or so and I'm just now getting around to playing with it. It is nothing fancy, just a Savage 110, but it is in great condition and hardly used, maybe 40 rounds through it is all. I'm going to do hand loads for it. I purchased some Sierra Game King 100grain bullets for it, and am looking for what powder you guys have found to be the most stable. In the Lyman book it says the IMR4350 and Vargat are the most popular. What are you guys using?

H-4895 and 95 gr. partions. Lotta deer with that load. Picked up some 4350 awhile back, but haven't messed with it yet.

I've been working up a load with Varget and H414.  I will chime in with results as I get back to the range.

I use IMR4350 for my .243

IMR 4320.  A mostly forgotten propellant, but it works great and seems to be more readily available than IMR 4350.  Sierra reloading manual lists bullets all the way up to 100 grains for this powder and that is what I use.  Accuracy is on par with any factory offering.  Plus it has a nice burnt powder smell aroma after you fire the shot that gets your heart pumpin'.

I have used IMR 4350 for over 25 years.  It has been very consistent, 1/2 MOA at 100 yds.
My 243 is a varmint gun and shoots the 87gr Hornady Vmax as above and the older 87gr spire point nearly as well. 
Not sure how the 100gr Sierra will do.

I shoot the 100 gr sierra's over IMR 4350, very accurate and push right around 3k fps.  this is out of my remy 700

IMR 4350 here too.  I settled on it long ago (25+ years) and have never deviated.

H4350 is my go to powder, and the 95 gr sierra matchking kills like lightning!

I got best performance with a 95gr Nosler Partition & IMR 4350 @ 41.4gr  Right at 1 MOA and chrono  at 3000 (+/- a few) fps.

My ancient Nosler book, circa 1976, shows a max load at 42gr.  as always, work up to max loads with caution.

I've used 4831 for the heavy bullets with good results. With the 55 ballistics I use H380.

Varget is like butter....Makes just about everything a little better.
H414 is another good choice.
Seriously Varget and the 51mm case were just about made for each other.

I just might have to try that....I love butter!

I use IMR4350 as well. 100 gr Hornaday interlock bullet. Lights out from prairie dogs to mule deer bucks.
