In my opinion Nosler’s load data is always quite generous with their velocities. Try to load to their stated velocity with a chronograph, watching closely for signs of excess pressure.
Haven’t tried Ramshot Grand, but bought two 8 pounders of Staball HD. Both are St Marks powders newly released. I’m going to be working with it this spring in a 270 WSM, and a 7mm Rem Mag. Load data suggests it will give good velocity and hopefully be consistent. I just cracked the seal on the...
In addition, I was getting 3127 fps from a 24” barrel, with 130gr Partitions loaded over 56 grains of Staball 6.5.
130gr E-Tips at 3150 fps loaded over 61 grains of RL26. Work up carefully with E-Tips, they will build pressure very quickly.
Lastly, I was getting 3060 fps with 145gr ELDX loaded...
57 grains of IMR4831 with a 130gr NBT has been the accuracy load for 3 different 270’s I’ve owned through the years. It’s a nice load to factory specs, 3000 fps, not a red line load.
You have a lot of room to work with from 53.2 grains of N160. About 5 grains worth. What was your velocity with the 130gr Accubond, as it seems like a very light load.
It’s entirely possible that they weren’t designed as being immediately reloadable. If it’s not reloadable the factory controls supply and demand, that equals price and who gets paid.
I do have a question. Do die manufacturers have to pay royalties to market and produce dies for a wholly...
It should be a good shooter. Bergara brought Mr. Shilen in to teach their techs how to build a barrel. I’ve heard that the Cascades are good quality rifles. Great find!
The heart wants what the heart wants, but what’s the reason to not let the optic perform the elevation calculation? I went off the premise that the riflescope calculates range and POI. If I’m wrong my apologies.
I’ll bet we are all using electric hydraulic presses to size and deprime before it’s over. Maybe not for everything, but steel cases seem to be where things are headed. I also wonder if they are using primers specifically suited to the pressure. What the headspace specs are as the case doesn’t...
Before Covid VV powders were what most other powders were compared to. It was the Cadillac of powders. Since Hodgdon and Alliant blew their prices sky high they have kinda been passed over. Hodgdon and Alliant invest so much in advertising that I think they have caused many to forget about VV...
32” of drop at 500 yards is pretty impressive. A 75gr boattail at 3500 fps sure would flatten out a PRS competition range, and lighten the rifles a good bit. I’m thinking a progressive twist barrel would extend barrel life for civilian rifles.
I used to have a 458 WM and ran mostly light loads in it. Looking back at my notes IMR or H4198 will work for you as well. I was running 300 gr. Sierra or Hornady with 50 grains of IMR4198 for a shade over 1800 fps. It was a pussycat in the heavier rifle. If using either 4895 I just stick to...
