Ok fellas, my new Ruger American Compact in 223 Rem came in a few days ago. Gotta say I loved the dinky toy-like size of it, really well balanced in the hands and coming to the shoulder for such a small rifle.

Threw a Redfield Revolution on it in a spare set of Leupy alloy rings - some PRW lows are on the way - and put together some quick loads to test function consisting of Hornady 50g SPs and 26g of H4895.

One shot to get on the bull at 60y was all needed after a quick bore-sight (I like that) and I went straight out to 125y.

I only had time to shoot the below two groups before a dust storm blew in (in fact winds were gusting near 40kph and it was well above 35 degrees C, so not great shooting weather!) but they were more than promising. The first group was 1.5 inches and the second was 0.55! Not bad for an out of the box rifle with an arbitrarily selected untested load!

You'll note I adjusted zero between the above groups.

Rain most of the next day so I didn't go out, but did go again yesterday twice to chrono and accuracy test several loads including not only the above but also the 65g Sierra GK BTSP and the 53g Vmax.

The below results pretty sum up where I am with this gun. Next pic shows the Sierra GK 65g, four groups with ascending charge weights, in order top left, top right, bottom left then bottom right. All the groups were very encouraging except the last at the highest charge weight of 25.5g H4895. In that case the loads were a little over pressure judging by the MV which was a shade over 3000fps. The three groups at lower charge weights averaged 0.68 moa (keep in mind the range is 125y)...

So onto the 53g Vmax which of course doesn't all go to plan. The top two groups in the next pic basically show about where I am at with this bullet. I've tried two powders with a couple of different charge weights each, but I am more like 1.75moa rather than the better than 0.75moa I am averaging with the Sierra (as evidenced by two further groups at the bottom of the below pic which were shot with a working load I've settled on).

Going to do more work with the Vmax today. I really want to like this bullet because it was a good BC for a light bullet and would be perfect for foxes and bunnies around the farm. In any case if it doesn't work out, there are other good options including the Sierra GK 65g which I used for a walk after dinner, rolling three rabbits in a five minute outing...

Anyway the little RAR Compact has pleased me no end so far. Very addictive to shoot and very cheap so plenty to like.

It definitely appears to be producing some good groups. The shorter barrel would certainly make for a stiffer rifle, which could mean better accuracy. I didn't note the twist on the Ruger web site.
 
Mike its a 1-8 twist.

Only downside is the mag can only take a 2.275" oal. So the 75 Amax and similar are out.

I think the mag constraint is what's hampering the 53g Vmax. That bullet engages the lands at something like 2.4+... Seating it at 2.27 might not be helping.
 
I went back out this morning and tried two revised loads for the 53g Vmax. From the speeds I was getting, it seems clear that this bullet takes some stoking to get it up to pressure.

I was initially using the Hodgdon / ADI data for the 53g Sierra bullet, but as this one clearly has a much different profile and by necessity is seated the better part of 0.2" off the lands, even with 1.6g over the Hodgdon max I was generating only mild speeds. 3120fps average for a load of 23.2g of H4198.

Anyway of the two loads I shot, the second (listed above) showed promise with a sub moa group of 0.99" at 125y, pictured below right in this pic...

The bottom left group was the same bullet and powder, only with 22.6g. The top two groups are the 65g with a slightly revised load of 24.7g of H4895. That one's a keeper!
 
On the subject, I don't suppose anyone owns a version of Quickload that has the 53g Vmax in it's reference data? I'd be very interested to see what is says about that bullet in an 18" bbl with a pressure ceiling of 60k PSI....

Most thankful if it can be run for me.

Thanks Mike. To push the boundaries of our friendship, could you run that last chart by substituting H4198 for H4895?

Please? :)

1:8 twist, you might want to experiment with some 69, 75 or 77 grain BTHP match bullets. They are designed to load mag-length in an AR-15 (2.260"). Slower out the muzzle, but very high BCs. Not quite as good as the A-max or 80 gr VLDs, but they hold their own to 600 yards. I've fired them at that range in some wind, and my shooting is not good enough to notice the difference in wind with the 75 gr Hor HPBT over 24 Varget vs. the 80gr Nos BTHP over 24 gr R15.

The 4895s are suitable propellants.
 
Ta Fotis.

Polaris, I've got some 68 and 75g Hdy BTSPs on the way. In any case, Holy Dooley, those SGKs shoot and they're not the shabbiest bullet for medium game either!

Love this rifle. A few months ago I'd have probably turned my nose up at one. Who'd-a-thought it?
 
The new Rugers all seem to be shooters.
So much so that I'm impressed.
Congrats on your rifle Bob. If it were me I'd be looking at the 68 or 69 grain bullets with your 1::8 twist. I run a 1 : 7 twist and it loves the heavier stuff.

Ruger definitely did it right making this in a relatively fast twist. Heavy for caliber bullets are the way to go in this caliber for anything bigger than prairie dogs. Wish Nosler would make a 68 or 75 grain AccuBond for small deer and antelope. Swift beat them to the punch on that one. 1:8 does just fine with 75-80 grain bullets. My 8 twist RRA is sub-MOA at 300m with both from a rest with optics.

My RAR Predator does fantastic things with the 77 grain Sierra Tipped MK at 2900. Accuracy is excellent and they seem to shoot pretty well at distance as well. A big plus is they can be loaded to standard length in the RAR's. I've looked at a mag mod but with the way it shoots these 77's I'll probably leave it alone for awhile.
 
I honestly can't say the synthetic stock is quite as bad and flexy as some have said. Mine was a fraction close to the barrel on the left hand side but I've since sanded that back and evened it out. Also adjusted the pull weight down on the trigger.

I've got an option on a Boyds laminate but I'm considering not exercising it given how good this shoots.

Anyway got a couple more Vmax 53g loads to try today including H322 / Ar2219 which looked pretty good in the QL analysis. The 68 and 75 BTSPs should arrive by the weekend.
 
Well you're probably all sick of this thread :) but thought I'd continue for any interested.

I think its time to shelve the 53g Vmax experiment for now. Three more load combos this morning really made little progress. Granted there was a pretty strong right to left breeze that made things hard, I was still around an average of 2 inches for three shot groups at 100y, as pictured below.

The group at the top left is the proven 65g Gameking load which went into 1.18 " which in the conditions (at 125y) was great and proved for me that the Vmax isn't behaving.

I've run them at mild pressures and hot as well, varied the seating depth and used several different powders, but not a lot of encouragement.

Open to suggestions, however with two very good working loads in the form of the 50g Hornady SP and the 65g Gameking - that both shoot to a very similar POI at 125y - and with more to try later, I reckon the Vmax can go back on the shelf for now.

Or should I just keep flogging that nearly dead horse? :?

Anyway the little RAR Compact has pleased me no end so far. Very addictive to shoot and very cheap so plenty to like.

Good lord, you could peel a catfish with those toes.
