From what I've read, there is.

Mine is a Take Down Model and has the 'special folding peep sight'.

The manner in which the Take Down works involves a notch at the tang which engages a fairly substantial bit of steel but I can't say that I've been less than concerned about cracking in that area.

I've loaded 42 grains IMR4895, pushing the now practically extinct Hornady 3715 (270 grain RN) with good results and have since read of others who use the very same load.

If I ever go for wild boar with it in California (where I live) the current regs require unleaded fuel (non lead projectiles). I have some Nosler 260 grain brass solids that I have not yet loaded which are longer than the Hornady 3715 and would intrude on case volume. When I get around to it (when?) I may start with a few of lighter powder charge and work up carefully, finding the lightest load that provides accuracy.
