I was wondering if anyone has Sierra load data for the 180 gr round nose for 30-06?
Thanks
Thanks
I believe sierra lumps all there 180 grain and even 175 in the same category with the same data. So btsp would be the same.
My apologies - I can't help you 'cause I don't own the Sierra manual. I only have Nosler 5, 6, & 7; Speer 13 & 14; Hornady 7th; Western 5.0; Hodgdon Annuals for 2012, 2013 and 2014; and I subscribe to Loadata.com.
Just to be sure, You do understand that any loading manual is based on their test barrel, their lot of cases, their lot of primers and their lot of powders? There is nothing saying that your components exactly match theirs. See, for example, the Nosler 5, 6 & 7 information for 30-06 - no one, ever, anywhere, has gotten RL22 to launch 165 grain bullets at 3,000 fps at 60,000 psi or less, except the run of Nosler's lot of RL22, in their barrel, on that day, in that Nosler lab. When loading, your chronograph is your very, very, best friend!
You don't need maker specific data. Any 180 grain data will do. Who made the bullet or its shape doesn't matter. You load for the bullet weight.
Manuals differ because the data applies to the conditions on the day of the tests using the exact components and firearm/universal receiver only.
Sierra doesn't distinguish between and neither does anybody else. One 180 grain bullet used by Hodgdon on the day they tested. Not every 180 ever made. It just happens to be a Sierra SP. They may be owned by the same holding company. Saw a list of who owns who and most of 'em are owned by the same company.
There are quite a few handloaders who will cling to the load books, and will look at 10, using the lowest of the 10 listed maxes, never wondering why they differ. Some have followed that approach for 25+ years.
That's ok of course, but that approach is the hallmark of a novice.
I'm sometimes torn. Do I simply answer the question, or address the "back story" and get a new one ripped? I usually do what "Potasminer" did, as there's still the chance that someone reading it (including the OP) will benefit.
Yes, I often wonder, when I see someone say he/she has been reloading for 25 years, do they have 25 years experience, or one year experience repeated 25 times.
Perhaps this explains more:
Now to answer the question from the Sierra Manual
Accuracy Load: Viht N550/ 49.0grs. 2600fps/ 2702ft. lbs.
Hunting Load: RE-22/ 56.0grs. 2700fps/ 2914ft. lbs.
Both loads can be started 2 grains less and both will gain about 100 fps by adding an additional 2 grains.
Nosler's most accurate load is 62.0 grains of Re22 but starting at 58.0 grains.
I loaded 180 grain and 220 grain RN bullets for my Remington 700 and both responded best loaded to the nutz.
I am well aware of all the variables that affect loads and load data. No I don't load hundreds of rounds per year for 20 different calibers, but the ones I do load for I don't have any trouble developing a good accurate load. I have a couple manuals kicking around as most hand loaders do, and the internet is loaded with most any information I want/need. As I said before, I asked this question more out of curiosity than anything, and I could have developed a load with the 180 rn no problem at all. I can guarantee you that I won't be asking for any info in the future.
OK shorttrac,..thanks for a civilized answer,....unlike Potashminers second reply. I'm not sure who spread the sh!t flavored icing on his cup cake, but I think he must have misunderstood my reply as something that it wasn't. I posted a simple question looking for a simple answer,..thanks again shorttrac,..I'll work up a load from the 180 spbt data.
