I have one and have no problem with it.To me it's a tough gun.No frills just BOOM.
I gave it to a friend to use and she shot it and never cleaned it,I got it back with alot of corrosion in the bore,cleaned it up and BOOM,everytime as long as I do my part.
I load it with 100g BH-209 / 200 grn Shockwave spire point (non bonded) / CCI-M primer / Center point 4x16x40 Optic
I put a Thumbhole stock on mine but the other was fine.
I am 6'8" and have big hands,the Optima has a deep pistol grip butstock that keeps my thumb out of the way and gives my trigger finger a straighter pull.
Before

After

This is a sight in target.
The target says 110 grn but I backed it down to 100 grn

I do not shoot well but the gun shoots fine.Good luck
