I would agree on the 22lr trainer idea. You can accomplish everything for a fraction of the price.
Pro’s
1 They will not buck the wind like a big round. This teaches you how to make wind calls
2 They don’t shoot very far. Teaches dialing in your elevation
3 Shooting @ 0-300 yards will make you use a kestral, rangefinder, ballistic program. Buy good the first time, you will use these for years.
4 buy a good scope, a viper pst is an excellent investment. buy once, cry once. These have very good resale value.
5 It’s a fraction of the cost = more savings for that first custom rifle your dreaming of.
Now this is what I did:
I bought a Custom rifle 338 Lapua Mag; Stiller TAC 338 action, XLR chassis.
I have bought micro dies, bullets, brass(Lapua), powder, case trimmer(Giraud), factory ammo($118/20), spotting scope, terrapin range finder, primers, mags, boretech cleaning rods etc, and new rings. To all this and I need a bigger scope. The 3.5*15 NF is not enough.
Just to give you a ball park figure, all that’s over 8K. I try not to think about it much atm. I got a good deal on the rifle for it being left hand action, but look at what I have spent this month and still need more stuff.
I highly recommend getting a 22lr and slapping a PST on her and shooting until you learn how to make a long shot every time. I do not believe you said anything about if you reloaded or not ??? It will end up being a MUST at some point. While you are shooting your 22, you can read up and see how to reload to make your big rifle shoot better. Most of the guys around here get a 6x47 lapua and drive it out to 1k or more. The guy that owns the guns hop here has a target with five hits on it at 1k the size of a half dollar. They shoot what they build.
All this can be done for less than 2k dollars, so if you decide you do not like it, sell your support equipment and move on for a far more cheaper price. Shooting long range is not for the timid.
