I attempted IMR 4451 in my new 300wsm, five diferent loadings to be precise and despite IMR4451's claim to acquire nearly the same effectiveness traits as H4350, my Tikka T3 mild didn't complete any much better than one.5 MOA, not terrible but IMR4831 gave me sub-MOA really to start with reloading.
Many thanks for sharing your experience, Russ. It can be tricky (or possibly harmful) to test to reverse engineer a load devoid of figuring out precisely what powder they are using, so I’d unquestionably advise warning there. Nevertheless it seems like you’re pleased with the results.
When distinct a great deal of a provided powder can even differ from five to ten%, I suppose its no wonder 1 chart can show another get from An additional 1.
Be sure to do not forget that these guys may be working “scorching” loads, and just because it’s safe inside their rifles doesn’t indicate It will likely be Secure with your’s. Go through my highlighted suggestion while in the intro of this text, and seek advice from a comprehensive reloading handbook for safe loading tactics.
Gonna just cling it about the wall instead of bothering with looking out a smith that could re-barrel and acquire it suitable working with a normal barrel.
I've a lot of accurate 4350. If I can't find load data for Accurate4350, I am going to use H4350 or IMR4350 load data as some a place to begin. But on no account would I am going straight to max or nearly anything.
I do know This can be off matter, but did you at any time have any luck With all the three hundred norma mag? I happen to be working with that caliber for awhile now and it is admittedly finicky for me.

As with any cartridge that headspaces about the shoulder, it’s ideal to adjust the sizing die to resize once-fired conditions devoid of pushing back the shoulder.
I not often get to max expenses so I wasn’t specifically concerned. The primary factor I used to be on the lookout for COL options and min load.
As for a connection amongst the two, Hodgdon owns IMR and manufactures IMR 4350 but that does not ensure it is the same as H4350. They have got very similar melt away fees but will not be interchangeable.
Most effective to simply reach 5744 powder out to Alliant and see what loads they propose. Although They might very similar burn charges They might act in a different way with tension curves.
The H powders have a lot more temperature stability then the IMR powders. You may see extra various benefits on the IMR if shot at 20 levels vs . taking pictures in 90 degree temperature then you should that has a H powder.
Don’t misunderstand, the 6.5CM is amazingly able. When you handed a six.five Creedmoor to 1 of these guys in the best one hundred, I wager they could still smoke me in a match (and a lot of Other individuals). It’s more details on the shooter than the cartridge! But, should you gave them a 6mm as an alternative to a six.5mm, they may have the capacity to location their very own shots a little easier because of a little bit
