Re: First long range gun
Chronographs are definitely helpful, but you can base your speed off the reloading manual. Look into the LEE reloading manual. It has some really good instruction and information in the front chapters. It would be a good starting spot. Get yourself a digital caliper from midway or a local store. Seat the bullets to the suggested depth and go from there. Never exceed load maximum as written in the manual. I know that I have gotten away with it, and many other guys have as well, but it is done with extreme care and caution when building up loads. Its best as a new loader to stay within the parameters of the manuals minimums and max loads for the given powder charge and bullet. Hodgdon powder is the most popular and readily used for hunting calibers due to its ability to stay consistent through temp changes. For the 7mmRM, I would suggest the 168 Berger, 160 Nosler Accubond, or the Hornady 162 Amax. All good bullets for the specified caliber and long range hunting. I would also suggest Hodgdon H1000 powder, or Alliant Reloader 22 for these weight bullets.
To do a barrel break in, just google it. There are a ton of different ways to do it, and just pick one and go for it. For break in you can use loads that you want to use for hunting, or just pick a random lighter load so you are not using up your powder.
