I find all these newer rimmed cartridges caliber .510 very interesting for someone who wants to buy a new DR.

The caliber 510 remains a highly interesting caliber for a DR because the ballistic advantages of the caliber 458 are combined with the power of a cartridge 577. A good compromise.

I am also a big fan of DR , but unfortunately see their use nowadays very limited compared to a bolt action rifle with a scope. I have repeatedly written on various Forums that if you want to hunt with an DR, you have to adapt the hunting to your weapon. Opinions are very divided, it is a topic in itself. Nevertheless, there are two DR in my gun safe, but for which I have little use.
