I've got an over-supply of new Winchester brass and a new Bartlein bbl in 7WSM so nothing will be changing for the next 1,000 rds or so. Even then, I might be incline to rebarrel in 7WSM which seems quite capable of duplicating 7 Rem mag ballistics in a short action. Accuracy in my rifle has been exceptional.My bad I meant Hornady is making brass but it's probably not the best. Bertram is stout, it needs weight sorted tho. 100 good cases will probably out last the barrel. A guy tested one piece of their 300 norma to 25 stiff loads before it failed. Have you considered 7 saum? ADG is going to have brass on market soon, it'll run withiw 50fps of 7mag when set up properly.
Thanks for the feedback,Our latest 7 WSM project may have turned out to be the most accurate hunting rifle I have had the privilege to shoot. I only have it pushing the 195 EOLs to 2900 but they land in one hole. It is a model 70 with a Bartlein 26” #3 barrel and it is delivering over 1600 ft/lbs of energy at 1000 yards.
They can hit 3000 with 162s in 22" barrels, I would think with a 26" stick 3000 is doable with a 180 class bulle or just under), just depends on where the accuracy node is though ..top loads of RE17 are 55-56 grains for max speedSounds great for target shooting but I'm wanting to drive the 180's at least 3000 FPS for elk.
These are being fired from new Winchester brass because I had a bag laying around from a couple of years ago. I am using Retumbo but RL26 should work well. There is a lot of bad press on Hornady brass but everything I have purchased over the past year or so has been great. I have some PRCs and 7mm mags with 6 shot on them and primer pockets are still like new.Thanks for the feedback,
Have you tried the hornady brass?
How about rl26?
I just put a load together with rl26 and the 180 eld-m in my 7×300wsm.
Easily reached 3000 fps, 1/2" group at 200 yards
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
