That 12 twist will stabilize a 62 grain Fusion, and that bullet is pure poison on deer. It's a hunting gun. It doesn't need a bench rest trigger.
Oh I bet I’ve killed a few deer, to put it mildly, with 62gr Fusions. A 1-12” twist is never an advantage. I’m not sure I’d use “worse trigger” as an advantage either.
Having used multiples of that very rifle and only going by actually using them from the factory and ignoring “feelings”- let’s see...
Remington-
Pros:
1). ......... it has a Remington name for those that care?
Cons:
1). Quality is atrocious overall.
2). Twist rate sucks and limits most of the best bullets.
3). Trigger is a horrible design, and for a variety of reasons should be replaced.
4). Barrels are just about evenly split in thirds between good/average/poor.
5). Action base screw about 50/50 misaligned.
6). Bolt needs bushed
7) Plastic stock is not rigid.
8). Feeding can be hit or miss
9). Bolt handles can pop off.
Tikka T3x-
Pros:
1). Overall quality is outstanding.
2). One of, if not the best factory barrels
3). One of the smoothest actions made. Action is totally square- everything is machined correctly.
3). Best factory trigger for reliability and durability. Can be adjusted in 2-3 minutes to be 2.5lbs.
4). Factory stock is quite stiff and is designed well (comb and grip)
5). Magazine feeds very well, is very reliable
6). Twist rate is good for most of the best bullets
Cons:
1). Doesn’t use AICS mags.
I have shot tens of thousands of rounds from Remingtons factory, custom, and issued sniper rifles. They can be decent guns, but they can also be junk. I have had triggers fail multiple times, multiple bolt handles pop off, half of the last dozen or so I’ve used had major issues with the reciever or barrel, not to mention what is probably the most garbage trigger made in a mainstream rifle, poor twist rates, half had precision issues, etc.
I have over 40,000 rounds from Tikka’s in the last couple of years. They’re on average have better precision than any other sub $1k rifle, the actions are straight and true, the triggers are probably the best in a sub $4k rifle for reliability especially in sand, the mags while not AI at least do their job correctly, the stocks are well designed and completely functional, the twist in 223 is good, they have an exceptionally durable mounting system with the built in rail.
