H322 vs. H4198?? Who uses witch one and why ? What are the differences in the 450?
I've always used h4198 but my supply is running low so I'm considering trying 322 as it seems some shooters like it.
When I started loading for my 1895 M 450 I pulled a bullet and dumped the powder in a scale, it weighed 58.0gr and it was a ball powder. I look up loads in manuals and internet for 350 gr Hornady bullets and ball powder with 58.0 gr. I found H322 in Hornady data that listed 58.0 as max with the 350 FN Hornady at 2200fps! I loaded this combo and it chronographed exactly as factory loads and it also shot at the same POI with the same 1" groups at 100 yds! I have been using this load for years now and even tried this load in other rifles and it works great in those also! BTW I tried the 325 gummies in mine and a friends rifles and it didn't shoot well in either rifle! Just FYI!
H322 is NOT a ball powder, but it is a fine grained powder that flows through a measure nicely. I use it in my 444 and find it very consistent and accurate. I believe H4198 is better for milder loads and ignites a little easier. H322 was a surplus powder that the Benrester's picked up. Many of the 'Benrest" powders work very well in the 45-70, 444, 35 Rem, 32 Special and similar cartridges. Some of them don't do well at lower pressure, but do very well in 'full' loads, others work as well as 4198, or better due to the more accurate flow through a powder measure. H322, Accurate 2015, Accurate 2200, Reloder 7, Benchmark many of the '223' powders work well in the 'straighter' sided rifle cartridges.
Just an update... I get an average of 70fps difference between H322 and H4198 out of my 450mxlr with published max load data and hornady 350gr flat nose. H322 being the faster.
Not much difference in my opinion...
I'm brand new to the caliber, but a buddy is offering me a like new Winchester 94 Trails End Takedown with dies and 100 brass for a steal.
I'm inclined to take it, because everyone else backed down when they heard the caliber, and claimed it to be a "Dead Caliber".
For the record, I have...
Lucky, kind of that the 450 Marlin is not real popular. At powder valley I managed to pick up 50 new 450 Marlin brass with shipping about $1.14 per piece. I'm stocked up for many years now as my custom Mauser 98 is easy on the brass even at 60,000 PSI.
