If I remember correctly, all Savage .243 barrels are 1:9.25 twist.

While that will give you a good indication of what weight bullets will stabilize in a barrel of that twist, it won't tell you what your barrel will like.
I have several 1:9 twist barrels that stabilize 77 grain bullets and shoot them great, but the stability calculators say that 77 grain bullets won't be stable in a 1:9 twist.

I have identical barrels in .308 caliber that don't shoot the same bullet weights equally well.
One likes heavy bullets and the other likes lighter bullets.

I'm afraid that even when some .243 shooters give you their best loads, you may find out that those loads don't perform well in your rifle.

If the barrel is a factory barrel they will shoot 55 gr to 100 gr very well. for groundhogs and paper I would try the 80 gr sierra bliz, worked very well in my stock .243.

I had a Savage model 11 in 243 that I took in on trade. I developed a load using 87 gr V-Max and as I recall, IMR4831. Shot terrific and son took his first deer at 220 yds with a shot to the ticker. Bang-flop!

The 9 1/4 twist somewhat limits the heavier bullets, but I've read of some success with 105 gr bullets. Of course the altitude where you're shooting does effect that.
