I've heard of that one being really hard on throats yet by the temp ratings varget and h4895 are just a step down and they certainly get a lot of use in high volume guns.
I was under the impression the powder rate charts had to do with speed off propagation or the " burn rate" not how hot temperature wise it gets. Seems to be a known thing the V5 powders are double base and are hotter temp wise and can decrease barrel life whereas the V1 series are not. Or am I miss informed?
Correct, the chart that everyone miseads runs <Faster-Slower> It has nothing to do with burn "temperature". Like all the VV and other double-base high pressure powders, they will burn throats at an accelerated rate.I was under the impression the powder rate charts had to do with speed off propagation or the " burn rate" not how hot temperature wise it gets. Seems to be a known thing the V5 powders are double base and are hotter temp wise and can decrease barrel life whereas the V1 series are not. Or am I miss informed?
Another thing is that the chart can be quite misguiding
For example it shows that N540 is a bit slower than XBR but in Quickload and GRT it's very close (at least in Dasher/Grendel sized case).
Powder burn rates aren't linear and theres a lot of variables ( single, double base, flake, ball, granule size, density, temperature, effect when compressed, etc etc)
I'd never select a powder/charge just by looking at the chart.

The same company that is considering selling Lake City ammo to the Chechs? What a bunch of American hating, pice of shit communist they are turning out to be.
Yeah, cuz they're the only company that produce their powder with nitro lol, what a joke. If you didn't want to sell to the public, just say so, you don't have to make shit up. As if them hiking their prices weren't enough...
I bought enough of their shit when prices were ok, definitely not interested any more

Would a 168-175 class of bullet fit in an aics mag keeping the bullet out of the neck shoulder junction of a 300wsm?
Should with SMK bullets. Let's say they fit in my m70 featherweight fine. The boat tail may have protruded below the neck/shoulder junction. I sold the rifle a couple years ago so I can't check.
I’ve been banging my head over this myself for 3 years and finally decided on a 300wsm mostly because I can by brass. I really wanted a 7wsm but I’m not going to jack with all the work and extra stuff I’ll need to convert brass from 300wsm to 7. Also I shoot 6 creed and have a bunch of 4350 so all I need was brass and bullets and dies for the 300. Your real problem like mentioned above is trying to make it a hunting/ target gun which I don’t see happening. Your gunna have to choose 1 or the other
I’ve come to this conclusion as well. I built a 6.5PRC for hunting/range fun. It’s 8.5lbs and I have no issue shooting it for hours at the range but the issue is I’m burning up the barrel on my hunting rifle while having fun shooting steel.
Need 2 different rifles or at least multiple barrels to accomplish both goals imo.
Bolt guns are almost the same firearm legos as the AR platform now. All it takes are a few tools to do the barrel swap
