Note I have never had a CCI primer are unsuccessful to ignite the powder . Try out chronying in colder temps you will see a decrease velocity typically, but its not a big offer, I've had a good deal of luck in accuracy using this type of powder. Attempt also IMR 4831 or H-4831 or 'sc'.
This creedmoor will likely be far more for extended array apply, and i shoot all year around, so i need a steady powder.
The four foot flame out with the barrel fearful the hell out of my Pal which was hog searching with me.gun)
I think if there'll be a difficulty It will likely be from acquiring a load when it's cold after which you can shot in the course of summer season.
I have utilised both MRP and RL-22 at distinctive periods in the exact same calibers, and while I find they are close in burn up amount I come across they're not the identical .I have witnessed around a three gr distinction in the same cartridge. In my 7mm wea mag I also located that MRP was extra temp secure than RL-22.
There are large amount to whole lot versions which make redoing the load enhancement important, particularily with the road of RL powders. They've got a historical past of vast large amount to large amount versions and in many cases recalls With all the RL 22 line.
We're engineers, reloading fans and work Among the most powerful ballistics calculators.
“This reloading powder is exceptional. It provides trusted efficiency and steady precision, making it an awesome option for any critical reloader.”
A single summer time working day I took it up from the mountains on a ninety five degree working day to carry out some throughout canyon capturing. When I could not hit the broad facet of a barn at 1K I introduced it in and shot at 375 yards. To my surprise I used to be Fortunate to maintain all pictures inside of four MOA! Which is when I learned about temperature sensitivity And exactly how undesirable RL22 was During this regard. Switched to Hodgdon H1000 and haven't seemed back again, greater ES far too.
We figured it absolutely was a foul primer. Was making use of CCI primers. Ordinarily we use federal 215. So you think that the hesitation might have originate from the powder in the cooler temperature.
Alliant Reloder 22 stands out for a smokeless gun powder regarded for its top-notch general performance and dependability.
This can be accurate. They can be both so very similar that the primary difference would fall into whole lot to great deal distinction classification. I have go through that MRP is first operate powder and RL22 is 2nd run in manufacturing that's a typical rationalization for why MRP is a lot more steady large amount to large amount.
I'd a foul batch of rl22 numerous a long time back and so they sent me a completely new pound of powder. I used to be examining my cabinets of powder and located that I've one reloader 22 more new large amount of a similar poor batch.
When applying RL22 with this particular combo it had been everywhere in the board right up until you got to a certain ambient temp and afterwards the velocity had a big spike.
