That's what I use, they do the job for me. One or two friends use the Sierra 174gn but I'm not good enough to notice the difference - apart from in the wallet...

39-41gn of Vihtavuori N140, or 38-39gn of Vectan TU3000 both with PPU primers have both worked well for me. Other powders/primers are available. Your mileage may vary. ;)

I use these with 41grains of Vitavouri N140 in my .303 rifles with good results.
Flat base bullets work better.

You are new to the hobby so buy a hundred pick a powder and load 30 of them go shoot them then come back and ask more questions.

If you're using an ordinary SMLE, neck sizing your brass will more than double its life. Some lucky milsurp and commercial rifles are tight enough not to need it.

The only reason you would not neck size would be if you were having problems feeding cartridges out of the magazine.

If you have two or more rifles with differently sized (or, occasionally, shaped) chambers, it's not unreasonable to keep the brass for each rifle separated. You can use a felt tip marker to identify which brass goes to which rifle.

As much as brass costs, I try to make it live as long as possible...
