Ruger 77 CR-What can a 16.5" barrel deliver?

I like how these new rifles look but I'm curious as to what kind of performance you can get out of a .308 from a 16.5" barrel? How much velocity would you lose? Is this really practical? I think it would be a really cool rifle if you had to walk all day or sneak through some thick bush to pound moose, deer and black bear.

Any feedback?

Have a look at Hodgdon's handgun reloads for the 308, this will give you some idea. I have a buddy with a 18.5' 308 carbine auto loader who gets around 2580fps out of 165gr. reloads, using Varget.
 
I'd expect a 16.5" 308 Win to chrony 150 gr. at around 2600 fps, 165 gr. @ 2500 fps, and 180's @ 2400 fps.

Still plenty of power, basically 303 British Ballistics.

How do you find the Frontier to shoot? Does it have lots of muzzle blast? Ruger is introducing it in the .325 WSM this year. I'm seriously thinking about picking one up but I just can't imagine how you can burn all that powder in a 16.5" barrel. How accurate do they shoot?
 
The recoil and blast are not that bad. When I first started I only did about 25-30 rounds on the bench. But for bench work i now use a PAST shoulder pad and did about 60 rounds last time. To give some perspective, I'm 6'2", weigh 180 (OK, 190 :redface: ) I shoot IPSC and go through a lot of major power rounds a year plus lots of slugs and a couple thousand centerfire rifle a year ( mostly 7:62 x 39) so muzzle blast is not an issue- I did however wear both headset and inner protectors. I got no beefs form other people at the range when I was shooting it but othey were all experienced shooters)

Recoil - its more like a heavy push than a snap you have to make sure you pull it back snug into your shoulder pocket and put some downward pressure on the foreend it likes to jump. I got lazy once and let the stock slide onto my arm and got a bruise but that would have happened with an '06.

Practicing from field positions sitting kneeling standing etc it's a dream & i can shoot it all day. no milk jug is safe out to 200 yards from the field positions. I'm running a leupold scout scope (heavy duplex) in quick detach rings but for load development I used a Burris 3X9 mounted on the rear position.

I changed the trigger to a Timney which breaks at around 2 1/2 pounds. The factory one is OK but is not adjustable & runs about 6 pounds, which to my mind makes load development in particular difficult to do. that's a personal choice others prefer to have a little more weight which can be done if tou leave the original ruger trigger spring in.

Mty best load - appears safe in my rifle but may not be in others - which is a bit below max was 66 grains of RL19 in a winchester case and a Winchester regular primer pushing a 180 Grain speer Grand slam which gave me 3 shot groups between 0.2 and 0.3 inches at 100 yards -off the bench, no wind. velocity was around 2735 FPS with not much variation. So i figure I get the same velocity as a 30:06 with a regular (24 inch)- barrel, and 5 shot groups should still be under 1" at 100 yards. - which gives me a feeling of confidence, although of course it's not intended for benchrest competition.

the gun carries like a dream:D . i hiked the bush for a week with it & hardly realized it was there. none of the hanging up on branches and swinging weight that i had the year before with my 26 inch barreled Ruger 77.
 
How much does it cost to put a Timney trigger in? Is it easy to do or should a competent gunsmith be hired for it? That's one of the things that I don't like about Rugers is the factory, non-adjustable triggers.
 
Brownell's retails theirs for $98.75 US (which is below the $100 limit so no import permit required) plus shipping, GST & PST. http://www.brownells.com/aspx/NS/st...itle=RUGER~+M77~+MK+II+ADJUSTABLE+TRIGGER+KIT

There may be Canadian suppliers & a gunsmith could certainly order one in.

It's not quite a drop in because you have to file/stone a small surface on the top of the trigger assembly to that it fits to the safety lever on the bolt. Timney marks the area to be filed & it's a case of file a bit, try, file a bit -I've done three and the last one took me about an hour and a half (I'm not a gunsmith).

The Timney to my mind makes a major improvement to the feel of the trigger squeeze.:D
