Home Forums Hunting & Shooting Long Range Hunting 6.5 GAP 4S vs 6.5 PRC

Pat, why don’t you make a short mag cartridge carrier while you’re at it!

Great shooting Pat!! Just curious. You ever run a dedicated copper solvent after the butch’s just to see if anything might be left? I know that a few years ago the butch’s solvent changed and it has been said to be less of a copper cleaner now.

I always look after I'm done with my Hawkeye bore scope...this barrel is 100% copper free right now. Barrels vary, some will build a trace, while still shooting great, others will be completely clean. I've found after the throats start getting some wear and tear, the lands will have an orange peel look,(rough)and they will build copper, and carbon there. I can still get it out with a good scrubbing with a bronze brush.

I'm not real big on cleaning very often. It the rifle is shooting good, I'll run it, and not worry too much about it. I did a test one time with one of my comp .308's. I cleaned it, shot three five shot groups, then didn't clean it for over 1,000 rounds, then before cleaning it, fired three more five shot groups. All six groups looked the same. That was a Krieger 1-11.25" 5R. It still shot good after 8,000+ rounds. I think there's been a lot of barrels wrecked by cleaning too often..

You mean like this one? Put together for, and by, yours truly....;)

Just like that!

Is that a prototype or will those ever be in production?

Check our website sometime this winter....it's in the works.

If my memory serves me correctly i'll try and give what I know.

George Gardner of GAP developed the 6.5 SAUM 4s it was designed to be the ultimate short action cartridge as well as offer optimal ballistics for the PRS series which has a velocity cap of 3200ft/sec I believe. Part of the design philosophy was to run long barrels with slow powders(H1000) to get the velocity rather than wringing the performance out by high pressures which ultimately attributes to excellent barrel life in proportion to the performance delivered. The one caveat of the 4s is currently hornady is the only brass available (some form brass from 7 saum norma brass and ect...)

The 6.5 PRC to my understanding was a Hornady/Ruger project that George of GAP helped work on. it too is aimed at the PRS market and is built with similar design principles of the 4s but uses the RCM (ruger compact magnum) as it's parent case rather than the SAUM. The 4s has slightly more capacity over the RCM.

For general purposes there so similar you could likely flip a coin and choose one. The big difference that I see is the RCM is backed by Ruger and Hornady so it could potentially go further in the market just due to the backing of such a giants. don't get me wrong the 4s has it's followers but most who run the 4s have to coin to spring for the best. the PRC could bring a new crowd into the ever growing sport especially when off the shelf guns like Ruger RPR hit the market.

Pat, would you mind measuring the c.o.a.l. with that 139gr Scenar for me? I don't have a way of measuring to the ogive.

Thanks, Rio7
