vykkagur,
Re-reading this old thread reminded me that there is a very detailed thread on the Simson Suhl .405 DR that was begun by the gunmaker when he finished the rifle. I can start a thread here to the original one.

My Miroku/Winchester 1895 TD .405 WCF has taken a lot of game in the USA and Cape Buff and warthog in RSA and most of that posted on various web sites. I can post a link on prepping the rifle for 400 grain Woodies and taking the buff in RSA if you like.

Those two threads should provide much detail and some basis for discussion. Let me know if interested and I will work on it tonight.

PS, glad you like the rifles.
