Remington Bull Barrel rifles
Hey StephenT, Depending on the price, "JMC" might just have what you are looking for.
A couple of years ago a buddy of mine got a BOSS equipped M70 in 270Win. He also had a 25-06 Remington Sendero. Well, as luck would have it, he was able to "occasionally" work my hunting rifles over pretty good with my hunting bullets loaded for them. Wouldn't have been too big of a deal except for the ragging I had to endure (occasionally).
Put up with it for 3 years and finally decided to correct the situation. I got a 308Win M700VLS and put a 50mm 6.5-20x VariX-III on it. I do like the Sierra 168gr Match bullets when the BBQ Lunch is being shot for, but I also had exceptionally good luck with 168gr Hornady Match bullets. I used IMR-4064 and Fed-210M primers in R-P weight-segregated and fully prepared cases.
The rifle shot consistently in the 4s (0.400"-0.499") at 100yds and sub-MOA beyond 300yds when the trigger-yanker(me) did his part. I do believe I was the limiting factor.
One last thing, I've had access to 5 of these Bull Barreled Remingtons (223Rem & 308Win) and in each case, they all had chambers cut to SAAMI minimum standards. I've no idea if this is intended by Remington, but it sure is a huge coincidence if it isn't. That provides for less working of the case and a tighter chamber fit for folks that Neck Size.
All that said, I feel sure there are other rifles from all the makers that will do what you want with good handloads. But, it might be just a bit easier to get to where you want to be with a Bull Barrel regardless of the manufacturer. And a high power scope is a necessity for consistant long range accuracy.
Good hunting and clean 1-shot kills, Hot Core
