I’d be interested in your load info if you don’t mind. What rifle? Thanks.I was getting 2700 fps from a 20” barrel with a max charge of varget and a 108 eldm. Shot small groups on paper too.

By chance does anyone know what kampfeld charges to do the .473 bushing to bolt face?
yes.Is it signs of pressure or a difference in velocity that comes from the non temp stable powders?
Came to reply the exact same.yes.
Agree. And fully understand your response. I should have asked a better question.yes.
It was a rebarreled tikka t3x. 223 bolt opened up and preferred prefit. I thought I had notes in my phone but couldn’t find them, it was right at a max charge (maybe just a hair over) of varget in necked down starline grendel brass and cci 450s.I’d be interested in your load info if you don’t mind.

Kinport peak was 125-150 to open a 223 bolt with fast turnaround. In case that’s an option for youBy chance does anyone know what kampfeld charges to do the .473 bushing to bolt face?

With powders that are not temp stable, is there a significant difference in POI out to 500 yards with the 6 ARC? Specifically a Hornady 105 HPBT, Starline brass, CCI 400’s and Leverevolution from a Ruger American Gen 2? I know this will be a general answer as different rifles do different things.
Does the pressure increase to a dangerous level in a modern bolt action rifle? For example a Tikka. Or in my case, a Ruger American Gen 2?
And for the POI question let’s say an 8-10” kill zone. Whitetail deer. Thanks.
Do you know what distance your dropping to 1800 fps with that load?I was getting 2700 fps from a 20” barrel with a max charge of varget and a 108 eldm. Shot small groups on paper too.
So in that statement, you're just saying that you haven't seen a dramatic change in speed that would change drops out to 600 yards in cold weather but you haven't done any evaluation of speed data with a chrono and hot and cold soaked ammo, right?The way to use Lever is to work it up in the hottest conditions possible, then drop it a half grain or so. You’ll lose a bit of velocity in colder conditions, but it’ll be safe.
At least in 223 I/we haven’t seen a notable change in POI or data out to 600 yards from 90°’s to 30° in a couple of rifles.

Depends on the situation and what you consider dangerous. It is unlikely you're going to injure yourself with a modern rifle but you can absolutely destroy brass and potentially damage rifle components if you've really screwed up. If you worked up the load in cold/cool temps that is already near max pressure (or above because you just backed off "pressure signs" which are usually well over max) and then fire it when its 100F outside it could blow out primers, destroy primer pockets, etc. Some powders reportedly spike quite a bit once they're over pressure so its potentially a compounding issue.Does the pressure increase to a dangerous level in a modern bolt action rifle?
