Do not know about 410, but, I bumped into the identical detail with Alliant e3. I started off capturing it in .40 S&W and perhaps despatched examination loads to Alliant for tension testing with good outcomes.
I take advantage of 296 and obtain great factory searching shells. In case you are employing Winchester HS hulls make sure you are employing the right data and the HS wad as its distinct with the outdated compression hull data. And continues to be now suggested, weigh your shot demand as many of them are light. You need every little bit of shot you can obtain in that hull. You might require to open up it up so it really is dropping a regular 225 grains of shot.
I am even now loading the previous design and style Winchesters while, haven't needed to vacation resort towards the HS nonetheless. Observed a DEAL on about fifteen flats of these a handful of decades ago, and acquired them all. I have only been using the new types for competition, but I will be functioning out quickly.
Like all universal loading formulas some load combos is going to be a slightly reduced load For the reason that universal demand is calculated on The premise of The mix of components which is able to provide the highest pressure degree.
The rest of the powders for 410 loads, Have got a burn off speed of all around 295, and just turn out burning up the hulls swiftly to begin with, and won't ever be able to obtain the 1350fps prior to the ammo goes about pressure.
Five pellet loads of OOO is usually a little bit iffy considering the fact that based upon precise diameter and alloy in the pellets one is using the whole load weight of all five pellets can exceed 3/four-oz.
Take note: Don't believe in the charts!!!! Do a few throws Along with the new accurate 2520 load data bushing with your device and body weight the throws to confirm you are getting the correct grain drops.
Powder seems somewhat dirty and perhaps burns up the hulls somewhat more quickly, I feel (continue to simply get five reloads with no too much close inspection and sorting-some past longer but need to have near glance following a several reloads). I’m conservative to the reloads and dispose earlier than several do I believe. Crimps are awesome in 99% with the hulls even as a result of numerous reloads. All round I like it plenty of to maintain applying it.
I have nevertheless to try 300MP, but from all stories it is a good 410 powder. I moved to W-296/H-110 quite a few yrs back, for the same causes that Bob states. Higher velocities with reduced pressures. It handles this industry nicely, and with very good situation lifetime.
three grains. Identical batch of boolits confirmed considerably less stress with 410 for the duration of Sept./Oct. I never experienced the prospect to work with it from the cold of your Winter season however. I really preferred it over 2400 for the reason that I could squeak out far more velocity ahead of foremost would set in...
