building a rifle need help picking caliber

[specter29]

looking into doing another rifle build but need help picking a caliber. build will be for coyotes and deer. Below are the calibers I currently have.

223 cz 527 varmint target
30-06 pump rem 7600 (my swamp rifle)
300 win mag custom build by Piercision Rifles

 

[ShtrRdy]

I'd go with one of the 6.5mm options. 260 Rem, 6.5 Creedmoor, 6.5x47 Lapua

 

[Creedmoor shooter]

I'll second a 6.5mm option. I'd choose a 6.5x47 or the creed.

I'd want something a little flatter shooting. Those dang coyotes don't always stand still for dialing drops and dinking around with holdovers. I'll buck the trend and suggest a 25 cal. 25-06 or 257 Weatherby.

6.5 may beat the 25 cal with wind at extended ranges.

Zero the 257WB at 300, and you're only a few inches low at 400.

If one wants flat trajectory then 6mm would be the better option. You can push a 105 berger or 108 eld to 3150-3200 with modern 6mms. Higher bc than the 25s making it flatter and buck the wind better.

What's the fastest 6mm you can build?

I'm not the person to ask. But your best bet for 6mm is to stay in the 243, 6mm creed and 6x47L range case capacity. After you get past those case capacities you start adding alot more powder with not alot of velocity gain.

6mm-06 Ackley is probably the fastest semi-common. I shoot a .243 and it's been pretty good. I will put a .243 Ackley Improved barrel on when it gets shot out.
If you want to go full om crazy, there is a 6mm-7mm rem mag, I think it's called a 6mm mach4? Or do a 6mm stw....lol

 

[ATH]

243AI, 105s at 3200-3300fps. If you go with more powder capacity in a 6mm you don't get much more velocity but you do burn the barrel out much faster.

 

[BEEMAN]

My 22-284 really flies flat with a 80 gr Berger. N570 and R25 get me to 3550-3600 fps. Might work for you.

 

[MudRunner2005]

I think you need a .260 Rem or .260 AI to round-out your collection.

 

[Bfmine]

260 rem

 

[dibbs]

I would probably go with an 8 twist 6 x 47 Lapua. Should be able to get close to 3200 FPS with a 105/107 grain load, and it will reach out as far as you want to shoot.

 

[L.Sherm]

6x47 Lapua
