I load my 45-70 with cast and coated 405gr. bullets. Great loads and you can tailor the power from easy to eye-opening. I also load revolvers with cast and coated bullets. IMHO coated cast bullets are the way to go nowadays if you are shooting lead.
That's exactly what I use. Bought a cheap battery-powered minnow aerator. The hose on it fits a large primer pocket. I stick a deprimed case on the hose then into the chamber. It cuts barrel cooling time by half...
I have a batch of Nosler 338 brass and a sample of 5 averages 90.4 grs H2O.
A batch of Hornady comes in at 88.9...
A batch of Norma I haven't water tested but weighing the dry fired cases puts it roughly between the Nosler and Hornady...
For what it's worth.
Same thing for me. I can't answer your Degressivity question but the update that added IMR 4451 to the powder base has a much faster burn rate factor than even IMR 4895. That doesn't match my own chrono and load data...
I believe that the test barrels used by bullet and powder manufacturers are "blueprinted" to the small side of the respective bore tolerances. So they get to higher pressures (and velocities) at lower pressures. If you look at the old load manuals they normally tested on production firearms...
This morning I installed the Quickload 3.9 update that contains the Enduron Powder data.
The 2 Enduron powders I have experience with are IMR 7977 and IMR 4451.
Back checking my records, the predictions for IMR 7977 in the 7mm RemMag are pretty spot on to my own data less than +/- 10fps...
I have used it in the 338 Mag with 250gr Accubonds, 250gr Part, 200gr. Accubond, and 210gr. Sciroccos. Good Accuracy although I didn't push it hard yet. Chronographing it, I find it's slightly slower that H4350 although the published data indicates it is faster. ???
Look at Hodgdon's website. They have data for similar weight bullets although different make. I think you could use that data for Nosler bullets. They of course have H110 data also...
I think so too. good compromise given the 1-10 twist. Should work with the calibers from 257 Bob through 25-06 and the 251 WBY...
BTW: The 100 grain Swift Scirocco is an awesome bullet. tough and sleek.
I have a Lyman. I spent 20+ years using the RCBS hand deburring tool. Don't know what I was thinking. Yes I like the Lyman and am satisfied with how it performs. I don't use it much if at all for reaming out primer crimps but for chamfering and cleaning primer residue it is fine. I have an...
