i think it has been cover on here before but..

what if any is the accuracy gain with the 20 inch over the 16?

i know the speed will be 150 to 200 feet more out of the 20. this im not too worried about. my shots are at the max 300 yards give or take so drop is not that big of an issue.

i was just wondering if the 20 inch held an accuracy advandage over the 16 that would make it worth packing an extra couple pounds around with me.

im looking into getting a specialized dynamics built rife (if momma lets me part with those funds)

but might have to settle for the RRA (not takeing anything away from RRA)

any pics that you might have of a 16 inch PP rig would be great, i just like drooling!!

thanks, BRIZ
 
Put it like this....when you start chopping down inches on the barrel then you start chopping down yards on the round.

With that being said, you can still be more that effective at 300 yds w/ the 16"...that's what I got!!! However, when terrain will allow for the 500+ yard shots...then the Savage 10 FP .308 WIN will be my weapon of choice!
 
"i was just wondering if the 20 inch held an accuracy advandage over the 16 that would make it worth packing an extra couple pounds around with me."
No!
If anything the shorter barrel will be more accurate. This assuming the same diameter barrel. Everything else being equal a shorter barrel is stiffer and on average stiffer is more accurate.

I'm interested in this thread as well, for I am actually looking at both the RRA PP and possibly the Specialized Dynamics. I'm also waiting for Scott's computer guru to update his website so its a little more user friendly.

I have been prowling this forum and others for a while now and I have only become a member here for this place feels like home and everyone here seems to share the same interest.....smelling gun powder and making the grass grow.
 
I seriously doubt that there will be any difference at all in acccuracy. You will however lose a little velocity when you drop down to 16" from 20". The other thing to consider is that a 16" AR with a typical varmint scope will look kinda goofy IMHO, as tall as it is long. I think the 20" PP looks perfect.

Maybe my review on the midlength will help. I have since snatched out the RRA NM and put in a Geissele DMR set to 2.5 lbs first stage and .5 lbs second stage. With either lower and either trigger I have shot some great 5 shot groups with the 50 gr Nosler BT's (factory loads). I shot my smallest 5 shot group yet Sunday with the DMR. You could easily cover it with a dime and have some to spare. I have shot about 5 other factory loads through it and they are good but not enough to consider stepping away from the Noslers. I thought it would like heavier stuff but I am completely satisified with my new PP 16 inch. It's a very well made little tack driver. The only thing that will be done to it now is a hogue grip which will go on tomorrow. The RRA NM trigger was very good but I was spoiled by the DMR in my R15 so I had to get one for it too.

Here is the DMR group from Sunday. I have heard tell that it takes 500 rounds to break in a RRA barrel. If that is the case I look forward to the time when my barrel tightens up these groups. The groups in my review are some of the very first 20 or so fired.
Before I get slammed about the tape, I recycle targets (you can actually see the same red construction paper diamond from where I shot the 75gr Hornady's in the review) and I had just tested some 60 gr vmaxs which it didn't like. The group of 5 shot with the RRA trigger is on that sheet too from a few days before and they were dead centered on the dot so I raised my elevation a bit and shot this group DMR.

Here is what I know and have been taught...like I said earlier, cut inches off of the barrel and cut yards off of the round. Speed (velocity)= Power. So for example, a 55gr round flying at 2000 fps will hit harder than a round of the same weight flying at 1800 fps.

Additionally, when the round slows, the wind and other atmospheric conditions will have a greater effect on the rounds path.

For eample, the current world record sniper kill was by a Canadian sniper. He ran out of his Canadian issued .50BMG rounds and had to be resupplied with US issued .50BMG rounds. If it hadn't been for the US issued .50BMG rounds, the Canadian sniper would not have had the distance and accuracy to make the shot.

I know that I am talking about a round and not the barrel length, however, it was the velocity from the round that allowed the kill. A longer barrel will give you higher velocity. Not saying that a short barrel isn't accurate and can't shoot consistent sub-MOA groups, but I'll take the longer barrel w/ the added velocity, power, & range...just my opinion...

Not trying to be a smart#$@ ( and with all the respect due to an active duty Marine, you guys are the best!)but I believe the current record was a double by a British sniper using a 338. The former world record holder's McMillan 50 BMG's barrel was 29 inches the Accuracy International 338's barrel was 27 inches. It was only about 130 yds more but what a shot on both counts. Those guys are unbelievable.
I understand what you are saying and would buy a longer barreled rifle if I was shooting over 300yds at coyotes on a regular basis and it probably wouldn't be a 223 either. I like the idea of higher velocity and flatter trajectory myself for long shots. The woods are thick down here in GA, we just can see em that far away.

No...you are 100% correct...I had a brain fart, sorry...been up since 0200 this morning. You are correct, the British Sniper w/ the .338 Lapua MAG out of the Accuracy International L115A3. The snipers name is CoH Craig Harrison. I knew that!!!!!! Sorry for the confusion gents! HE IS THE CURRENT RECORD HOLDER. He beat out the Canadian Sniper! Still think I got the point across of what I was trying to say!!! lol

For clarification... The British sniper is 1st, Canadian Sniper is 2nd, and USMC Sniper GySgt Carlos Hathcock is 3rd using the M2 .50 cal Browning Machine Gun (on single shot w/ scope on top) back in Vietnam. Again, no ill feelings and glad you caught that...I hate passing on bum scoop!

I could've sworn I saw on RRA's website sometime that they say you don't need to break in their barrels...anyone else or am I just seeing things?
 
Hoskins, one of my best friends was a USMC Captain and got out a couple years ago, he was a Berzerker. You may run across another officer I know soon, Andy Scripture just got transfered up your way.

You guys know your business and we love you for it. You make us proud!

same in the nc mountains, there's no way i would go back to a 20" heavy barrel for coyote hunting. as light, as short, and as fast pointing as possible in the thick stuff.

Thanks skull creek, I'll be on the look out for a Capt by that name. Thank you for your support and kind words as well. Additionally thank you for calling me out on my error. Like I said, had been up for a while & had a brain fart, glad you caught it because I hate passing on inaccurate info!!! Good Catch!!!
 
Mine's a 20" and holds under 1-MOA at 300yd. which is as far as I've shot with it. Hard to find a good range farther in my neck of the woods. On velocity you'll lose about 40 fps per inch. If your gonna partake in a little close quarters battle with ol'Wiley go for the 16" :)
 
Well I too was lookin ag a specialized dynamics or rra and I got.in.touch with scott I gave him an idea of what I wanted and.my budget week or so ago and haven't heard back. Guessin he's busy. But if and when.I hear back from him ill make my decision. Unless. I vet impatient then ill go with the rra after all the good.things I've heard
 
i just talked to him a few days ago, he has been real busy getting ready for the shot show comming up next week.

might be worth PM'ing him with a reminder, he has so far been GREAT to work with, deff goning to get one of his rifles VEARY soon!!!
