Reloading: 250 Savage 87g Speer Hot Cor & IMR 3031
HTML-код
- Опубликовано: 22 окт 2024
- Welcome to Cloninger’s Garage. In this video, I work up some reloads for 87 Speer Hot Cor bullets using IMR 3031. The focus was to load up to a higher pressure than suggested for the 250 Savage. I was trying to reach an avg. MV of 3200+. We had planned to get velocity readings (we did not get all of them), but we experienced some technical difficulties.
If you have any recommendations on how I could improve my delivery please comment below.

My 99 loves, loves, 87gr Speer Hot Cor’s over 37 grains of IMR 4064, running 3050 fps. Accurate 💯
But Mr HappyFunGuy, isn’t that 2 grains over Speer’s listing?
Yes it is concerned reader, both my primer, case, and self will tell you it’s no problem at all!
Many times when using a light weight barrel l will do 3 shot groups do to barrel heat .
You need to change bullets. Never had good luck with hot cor speer in my ruler RSI International. Best load was 36 gr 3031 , 75gr. Sierra hp. We'll prepared cases,Win. primers. 1/2" grps at 100 yds and 3/4" at 200 yds. And that's no BS. Out of an 18 1/2" barrel. It's all in the components being assembled. Search for what your rifle likes and stress on case preparation
Very true, I use different components for my other rifles and there is definitely a difference.
Why did you load the first 5 with only 34 grains?
I look at several different reloading manuals. Hodgdon has the max load with IMR 3031 as 34g, so I started with that load. The max pressure by SAAMI is 45,000 cup. I know that is low per modern standards but that is what the specs are for a cartridge developed in 1915 for the Savage Model 99 lever action. I started at this load with the intention of trying to reach pressures that are possible in modern bolt action rifles. I hope that answers your question. Thanks for watching and leaving a comment.
If you want a 25-06, just get one. Running those pressures, disclaimers aside, is irresponsible. If you're going to do this kind of thing, keep it to yourself.
To each his own. Modern bolt action rifles in 250 Savage can easily be loaded above book max (45,000 cup) without pressure signs. As stated before, the saami pressure was set at 45,000 CUP or 50318 psi when it came out in 1915, due to the 250 Savage cartridge being used in lever actions. Modern bolt guns can easily handle 62,000 psi; thus resulting in higher muzzle velocities. Thus the experiment was a success. Thank you for watching and commenting!!

Sorry to disagree. It is irresponsible to advocate exceeding industry pressure standards. Your disclaimer will not protect you if someone chooses to act on what you're doing. You're demonstrating exceeding known safety standards. You have not shown any pressure testing apparatus and therefore have no idea what your pressures actually are.
There are too many variables in ballistics to just cross your fingers and hope for the best.
And c.u.p./ l.u.p. and psi do not have direct conversion standards. Ie, 45000 cup in the .250 Savage and in the 7x57 are not equivalent, and do not convert to psi.
You can do what you want with your rifles. Finger, eyes, etc. But putting it out there for less experienced folk is asking for a lawsuit.
Just because one can, it doesn't automatically follow that one should.
I'm not trying to pick a fight. Just trying to spare some real trouble. Consult legal counsel if you doubt what I'm saying. Cheap insurance.
@@marksellers4875 Fair enough!! I hope you will look at some of my other content as well. Thank you for watching and commenting!!
