Re: Remington VTR R15
The Remington VTR R15 is a Bushmaster 223. The Remington R25 is a DPMS 308/243 etc. They are owned by the same company.
I use several auto loaders for prairie dog/ coyote. Colt h-bar 223 with an Armalite trigger works great for prairie dog or ( coyote with 60 nbt bullets ).
In my opinion, the best coyote rifle is the DPMS LR 243 or the DPMS 243 L.
The 243 anchors these large yotes better than most 223 hits. The DPMS products are very well made and accurate. My LR 243 shoots 1" at 300 yards!
The 243 L is a lite weight model with an 18" barrel and is shoots almost that well.
If you hand load suggest 70 NBT 41.0 gr Varget CCI br primer.
The only problem with AR15/AR10 platforms is carry weight and noise. In most coyote hunts you need to enter the area undetected. Sight, smell, sound, can alert you target. You can't silently chamber most AR's and some safeties make a loud click also.
