When temperature insensitive powders, were not obtainable, we knew how to regulate for them. There's a entire different Environment available.
Undecided what pressure transform or velocity adjust was. I'd be interested to understand if Many others have examined this powder for temperature sensitivity.
The gap from chrono to muzzle is about 10 ft. I didn't have a tape measure but made use of actions so it had been inside 1-two ft at one of the most. I just forgot the tape evaluate is all. Should really I be positioning it more than that? from . Click to expand...
Obtaining two 280AI's during the spouse and children - both have twenty five" Kreiger barrels and the two use 168 VLD's, I can be incredibly stunned if you can find nearly 3000 fps with any Hogdon powders Except you actually drive the envelope at max. My son has attained 3000 but only with RL22 and we have practically tried out every thing.
You may try out 63 grains of Retumbo Together with the 168 Hunting VLD Nosler brass and either a WLR or Mag. primer is determined by the temp in which you will be hunting in ? That ought to get you rather darn near to what you need out on the 280 AI.
Exams have conclusively proven that H50BMG yields incredibly minimal Excessive spreads in velocity and stress. All of this translates into smaller groups at extended ranges!
If 10' from your muzzle is Doing work in your case - go with it. If you start observing hybrid 100v velocities, ES, and SD numbers not incredibly uniform I have found on some calibers where ten' just isn't plenty of distance since the muzzle blast was doing a little Peculiar factors Together with the velocities.
Seems like the .260Rem 95gr or 100gr hundreds must be just like that but Hodgdon's Web site would not even checklist a load for those weights.
I will probably just work up a load from the max load for the 280 rem, like start out at 51gr and transfer up in .5gr increments with a 168gr VLD. allow me to determine what you think that! factors i is going to be using are as hybrid 100v powder follows:
I'm only having about 3100 fps outside of my Remington Mountain Rifle With all the identical load, I have to have an incredibly sluggish barrel, receiving Nearly 3300 could be wonderful. Precision hodgdon hybrid 100v is exceptional. The temperature sensitivity situation will not look like that large of the deal as I discussed in advance of there was no discernible alter in poi when likely from 70 degrees humid to twenty-eight levels dry.
- At what length before the muzzle are you presently environment your chrony, and will you be backing that distance out on the ballistic calculator to catch up with to your correct muzzle velocity?
With regards to precision shooting and reloading, the choice of gun powder could make a substantial variation in effectiveness. Just one identify that stands out during the realm of reloading fans is Hodgdon Hybrid 100V Smokeless Gun Powder.
My current load is rapidly and exact however the bolt elevate remains greater than what I would like and will most likely again down An additional fifty percent grain and check out.
Basic Remedy in my case was backing from the load as I had as good of precision as I had been gonna get out in the rifle (It is best load in H414 was the exact same, but 100fps slower).
