0-600yrds target caliber

[sawcarver]

6mm Dasher 1-7 5T all the way. Works great from 0-600 and also can do very well out to 1k. You dont need more horsepower, just burning extra powder and barrel life

If you had a 223 BF a 223 1-7t shooting 80.5 bergers is also great out to 600

i just finished shooting the IBS 600 yd Nationals with my 6.5-284. Big mistake. Of 105 entrants, 95 of them were 6BR variants. I was Not even competitive.
If you want to shoot 600 yd BR, it must be a 6BRA. If F Class, a 284 with 180 gr Bergers.
Find the discipline you will shoot, find what wins, and do that.

Without a doubt the 6BR family of cartridges. I own several 6BR, BRA, and Dasher. I shoot 600 yard benchrest and 6 BRA dominates at least among local shooters. You do have to fire form that cartridge but it's pretty easy. You can get 6BR brass from Lapua. You can also get 6 Dasher brass now I believe but not Lapua. I fire formed my dasher from Lapua 6 BR. Depending on how serious you are and how far down the rabbit hole you want to go you will be happy with any of these but the simplist is the 6 BR with Lapua brass. A number of companies make dies. I use forester dies. Harrell brothers machine shops will get you a custom resizing die if you send him a few fired cases for under $100. PM me if you have any further questions about your choice or setup.
Here is a 1.5 inch 5 shot group at 600 yards my 11 year old son shot a couple of weeks ago in competition with my 6 BRA.

Another vote for 6 GT. Easy to load for, Alpha and Hornady brass available. Feeds well from AICS mags without modifications.

6 CM is hard to beat. Use it for small competitions out to 800 yds. Started with 108 ELD-M, but like the Berger 109 Hybrid Target better. I have a 6.5 CM equipped the same as 6CM ( chassis, brake, weight around 16 lbs) but harder to stay on target with 6.5

223 with fast twist barrel and 80ish grain bullets. I use a 223 trainer to 900 and it's awesome fun. Shooting that thing suppressed is pure joy

Sorry my 6-TCU isn't yet finished, so I can't tell you how it does. But from what I've read it should be a shooter. Looking forward to punching some "bug holes".

Ya I feel like that is the way I would go in this situation. Touch more horsepower than the Dasher but feeds from AICS mags because of its extra length. Even with the slightly longer case there is room to load the longest available bullets in the shortest COAL mags. Basically don't have to worry about COAL or feeding but still hit that barrel life/recoil sweet spot the dasher is known for. Last I checked Hornady and Alpha brass were readily available.

When talking about target shooting, do not forget about recoil, when one may want to put 100 plus rounds down range. Hunting firearms are not as critical due to wanting to sight the rifle in and make sure one can hit the target. The Military, by necessity, has acquired a lot of research on interactions with the human body. When troops are on the battlefield, they may be in a fire fight for days and when their shoulder has had enough, they have to just keep at it regardless. Certainly the information is based on the average person and of course there are variances from person to person. The information indicates that the threshold of recoil, in extended shooting session, is about 15 Lbs. Force before one starts to flinch. That being said the 6mm should be a breeze at around 5 to 6 Lbs. recoil. The 6.5 mm in the short action are around 10 to 12 Lbs. recoil and the 7mm-08 is about that and a little more, maybe up to 14 Lbs. The .308 is about 15 to 18 Lbs. recoil and the 30-06 is about 18 to 21 Lbs. recoil force. Here is a link to the Chuck Hawkes chart for recoil Table of firearms: https://www.chuckhawks.com/recoil_table_exp.htm and here is a link to Accurate Reloading recoil Table of firearms: http://www.accuratereloading.com/recoil.html
The felt recoil can vary depending on stock configuration and variations due to reloading configurations.
Personally, if I am target shooting, I want to enjoy the event without having to stop due to having enough pounding for the day.

Easy to load for as well. Works well with several powders - Varget, H4350, Staball, Shooter's World Precision and others.

6PPC. Made expressly for 100-600 yards.

 

[Fester Bestertester]

I would go with the 6 Dasher. Thousands of BR shooters would agree. I have a 6BR (I didn't realize factory brass was available when I built it) for my own enjoyment but my range maxes out at 400.

 

[Idgunner]

You will learn a lot and do it cheaper if you go with a 7 or 8 twist 223. My 8 twist 223 with 77gr STMKs is murder on chucks out to 620 yards.

Hi everyone,
Im looking to have a new built on a rem 700 short action that I got.
Rifle will ne use for 600yrds range target.

Have a 284win, 7mm rem mag, 7mmm08, 2 308, one will give is action.

As you see im a 7mm fan and with the rem mag im well equiped for long range hunting.

I do think solding one 308 and go full custom but I like to use what I got at home.

Im looking at the 6mm dasher but im open to any idea.

I dont mind single feeding my rifle.
