Welcome aboard the 404j experience. I recently gave my custom FN Mauser in 404 an excursion on Northern Territory Buff.
Using Woodleigh 400g RNSN loaded in Bertram Brass with 79g ADI 2209. and 400g Hydros with same powder charge. I Stalked in on two young Bulls. My first shot was at 80m. To my surprise he basically went down almost where he stood. As I gazed on admiring my handiwork, the local I was hunting with advised me to shoot the other bull as well. He had only moved away a further 15m. I duly took the shot and on this occasion the 2 to 3 year old travelled about another 20m before expiring. Neither animal required a finisher. Both were taken with the RNSN pills. It all seemed a bit surreal and anticlimactic. Two shots for two down. All the anxiety about loads,bullets and shot placement were gone.
Some pics of this rifle by Bob De Vries, Kudu Services are on here somewhere, but with the changes to the site, i am having trouble navigating it.
Time allowing in the future I will try and provide a more comprehensive report.. oh anyone that read previous posts when I was recovering from a shooting shoulder reco, which,subsequently failed, I barely felt the shots.
Cheers
Good hunting
