Hi. I'm new to this forum and have only been to Africa twice, but, being a mathematician and engineer, I tend to study and accumulate as much data as possible. The information on the threads here and on other sites has been extremely helpful. This information, coupled with almost 60 years of hunting elk, moose, deer and caribou throughout the US and Canada has led me to make two important decisions which will come to fruition next year. I have been blessed to have a great friend in Newfoundland who owns/operates the 4+ Star rated Tuckamore Lodge in Main Brook, Newfoundland, Canada. I have hunted there almost annually since 1986 with friends, my children and most recently my grandson, for moose, woodland Caribou and bear. I have taken over 20 moose, several really nice caribou and a few bears. 46 years ago, I purchased a .300 Weatherby Mag for an elk hunt in Wyoming While that firearm was an excellent rifle for that and subsequent elk and moose hunts, I became intrigued with Blaser Rifles. Since I had untold .300 WBY ammo laying around, I purchased a Professional R8 with a synthetic stock in ,300Wby topped with a Zeiss IC scope and a second barrel in .22-250 topped with the Zeiss scope that came with the Professional Package. The first trip to SA saw a nice Kudu and a Gemsbuck fall to the .300 and a Springbuck, Blesbuck and Impala fall to the .22-250. Last year I shot a Springbuck Grand Slam which in the East Cape is a regular, Kalahari, Black, White and Copper Springbuck. I used a Browning Model 78 with an octagonal barrel in 25.06 since I love that rifle buy had not used it much in the last 30+- years. I put a new Leupold VX5HD scope on the rifle with a CDS dial and obtained wonderful results. This year I will take a Waterbuck, a Blue Wildebeest and a Nyaka, once again using my Blaser in .300 Wby. 2020 will be the year of my Cape Buffalo and I am have purchased a Blaser Big Bore stock with a Safari barrel channel, a steel receiver (adds 1.25#) and a 1 lb. Kickstop recoil reducer in the butt stock. The Kickstop not only reduces recoil but adds weight to balance the safari barrel. It will be topped with a Leupold VX5HD 1-4 x 24 firedot scope with a CDS dial for longer shots. I can actually purchase the parts on line cheaper than the whole rifle and can use the bolt housing and magazine insert from my .300 Wby and possibly the bold head as well, saving money. NOW, THE $64,000 QUESTION!!! What caliber barrel?????
