Have used a similar sling for about 30 years, spreads the weight, frees up the hands, the one we use can be adjusted to four or five different positions or styles - makes it so even heavier rifles are not nearly the burden they can be with a conventional slingWithout knowing more about your hunting style or method I will have to make some assumptions. First of all I assume you are not carrying a heavy pack on this hunt so you are just concerned about the rifle, the gear in your pockets and a small pack for water and snacks. If that is the case you probably don't need a new rifle you need a new sling. IMHO the sling in the attached link is the best sling for a hunting rifle on the market. My family members and I have used this sling for year including last year safari and I can confidently say this is the best sling I have ever used.
This sling is currently sold on Amazon for $35 and that's a lot cheaper than a new rifle and scope.
Being able to distribute your rifles weight across both shoulders and have both hands free to climb a mountain makes all the difference in the world.
Yeah, I did my first goat hunt with a 338 because that is what I had. I got back from that trip and bought a weatherby mark V in their light weight mountain rifle in 280 (about 2.5 lbs. lighter). A person can lose weight in the mountains but a rifle will never lose weight with the exception of hopefully losing some lead. If you do lose that lead though hopefully you are coming out loaded heavy where 65 lbs is considered light. The question was brought up earlier about losing weight around the waist or in the equipment. Obvious answer is both but more weight in the equipment just makes the travel that much harder and if you haven't lost that last few pounds before the hunt you will probably lose it during. I know I do.It's when you add a 65 pound pack and go 10 days straight that the little things start to matter.
No doubt if you've never used one it could seem that way but after using one for a bit, you feel lost without the additional haskmarks.I looked into the Rapid Z system of Zeiss, but feel it is very "busy" in the scope, (from looking at pictures on the net of how it works) I will have to use it before I make say anything else.
Have never used one but I know a lot of people who have tried them and wouldn't use anything else now. I have a compact Leupold (2-8x) on my mountain rifle that works for me and is under 12 oz. in weight and has never let me down. Most would consider it too small but like I said it has never let me down in the mountains and it's a few oz. lighter than most scopes. Save weight where you can because you will feel every ounce that you carry.No doubt if you've never used one it could seem that way but after using one for a bit, you feel lost without the additional haskmarks.
I got a lot of RWS ammo with the rifle 173 grains not sure what the speed is though and also some Blaser ammo. Have had no problems so far.
Perfect for deer hunting from a stand but, I would not use such a short barrel in 308 Win for shots out to 400 m when Kudu are involved.
Those guys at Leupold keep things a changing and it appears they have ditched the old 3x9x33 and now have a 2.5-8x36mm in the VX-3 line, and its only 11 ounces, so that saves you 3/4 to a pound compared to some larger scale scopes and about 1/4 lb on the VX-5 2-10s and VX-6 2-12s. A 2.5-8 should be plenty on most African shots.
I like the Sako rifles, I have loaded for a Tikka T3 in 300 WSM and I own a Sako A7, which is very similar to the Tikka. The only issue I had was getting hand loaded bullets on the lands and still fit in the Box Mag. If you just shoot factory stuff this isn't be a problem. Sako factory barrels are really really good. The basic A7 weighs 6 lbs 6 ounces so plus the scope that's around 7 lbs 2 ounces, not a Melvin Forbes weight rifle, but still pretty light.
