Two more sleeps till my new actions come in.

Mystic, what is your theory for why we're getting the velocities we're getting from a 21.75" Rock Creek barrel while getting consistent groups? The barrel is a 1:10 twist and we've gun juiced the barrels but from your point of view how is 2800ish fps possible?

Simple....you just added more powder!

SAAMI specs put the 175gr velocity under 2700fps as does US milspec. Going higher, you are simply running more pressure - like the BR shooters.

With a tighter smooth bore and strong lock up, you are seeing some tangible improvements. Just be careful that you are not so close to the edge that a few psi spike locks things up.

Running standard cartridges at magnum or higher pressures has been done for decades.

I guess I find it hard to believe that people on this forum are calling B.S. on us for having accomplished this average feat that has been done for years all over the place. I was running 47gr. of Varget out of my 700P with 168gr SMK and to 500yds, I was dropping 12.5MOA from my 100yd zer. Those rounds were pretty hot already. From 7.25MOA to 12.5MOA; that's a huge gain in long range trajectory.

I don't think it is unusual at all to see loads and velocities like that from a premium barrel, they tend to be able to run higher pressures with accurcay than factory guns, but as was already stated, when e run them that high , the threshold is very close.
Short range bench resters carry this to the max, as do the 1000 yard guys that are very competitive.

FWIW, I had an Anschutz barrel ( 308 Win)on one of my silhouette rifles that would do 3,000FPS no sweat with no signs of pressure and was super accurate.
Go just a bit more powder however, and things got tight pretty quick!!

Glock, I am confused. Are you refering to me or some other posts?

The spookiest load I know of that was used to compete at the US nats last year was 155gr Berger at a bit over 3100fps. In a factory Savage F(TR) to boot.

I bet shooters would go pale if someone they put a strain guage on a number of common BR loads.

Imagine what they would think if someone said a 6BR can push a 107gr bullet at 2900fps. Similar to a 243 some 50% larger!

Pressure, what pressure??????

Just tell them about the 3100fps 155gr Berger load. That will give someone a stroke :)

If they don't believe you, ask them to search US Savage F class team 2007. It was one of the team members that was shooting this load. Me thinks a wee bit toasty.

Also, they can also reasearch F(TR) 308 rifles which are pushing 208 and 210gr VLD bullets AT..............2700fps. That's a spicey a meatballs.

The only thing I caution is you guys are not playing with table top rifles. They get dirty, wet and fired under varied conditions. At elevated pressures, there is little room for pressure spikes.

When playing, that will cost you a few points or a relay. In a working gun, it can get a whole lot more exciting.

PS caution should be taken with any loading that exceeds SAAMI specs and is not recommended. (see mr Lawyer warning lable)
 
The only thing that I can say about any nay-sayers should they arise...well, it's acutally quite inappropriate and involves multiple uncomfortable positions. Either way, it takes 9-9.25 moa for mine and two other peoples bullets with almost identicle rifles to get to 500 yrds. And these same loads punch a nice iddy biddy egg shaped hole in paper at 100 yrds. If someone wants to argue with that, they can sure as hell try.
 
From reading the posts I think most people don't have a problem with believing its being done.I think they are just questioning how bright it is to do so.

With NO pressure signs at all and carefully working up the loads under very controlled conditions, using the very best equipment available, why not.
Make no mistake we are not suggesting to "hot load" ammo for a factory rifle, just posting what we have found on some high end custom rigs and some experimentation in load development. nothing more.
 
I get more pressure signs from a stinky fart then what we are getting. But again, each gun is different. Just not ours....hehehe.
 
At any rate, this weekend promises to be warmer then last so if pressure signs stay consistent, we're laugh'n. We'll be throwing lead out to 1000yds hopefully if winds stay down and be able to post more results.
 
We will keep working at it. I'm pretty confident within the next three years we will be the premier match in the BCRA's schedule. We just have to work together and take care of business for the benefit of us all.

Can you shoot in the BCRA Sniper Match if you are rather new to Precision shooting :confused:
Please let me know I would really like to go...

Absolutely, come on out.

PM me your email address and I will send you all the necessary paperwork to get your membership and entry in.

Do you have a partner? If not we usually have a few without partners that show up on the day of the match and they team up then.
 
We had a cold day in the long range shooting department but managed confirmed zeros on three of the guns build with all of the same load developement. The target was 975yds away at 2800 ft above sea level and our guns needed 31MOA over 100yd zero. We needed 3MOA windage to maintain dead on hits but the consistency was there. Out to 1125yds, we all needed 42MOA to make long skid marks on the gongs. The 338s were slightly better at 21 MOA to the 975yd target and 25.5MOA out to 1125yds. Now, I think we're all ready for Summerland.
 
Well, I've officially sold my soul.

One small change to my ATRS built 308. S&B 5-25 PMII:D

Now my 308 wish list is complete!!:cool:

Looks good buddy. Maybe we'll let you shoot with us even though you crossed over. It will fun comparing the Nightforce to the S & B. See you in a week.

Cheers,

FFP is the biggest reason for me. Second would be the turrets. I like the fact that I can be more precise with hold overs and windage adjustments at any power without using the turrets for adjustment. The P4 fine reticle is a big step forward at the higher powers, doesn't obstruct the target like the thicker reticles did. However, at 5 power its very faint (that would be the only trade off). All the adjustments are very precise and crisp, glass incredibly clear. The scope itself is built like a tank. The NF is 31 oz and the S&B is 38.0958 oz so not "that" much heavier, it is bigger though.

I've always wanted one so what the heck, I had Rick build the rifle I wanted, it was killing me not to finish it off with this scope:D

I moved my Mil Rad NF over to my 300WM and I'll sell off the Leupold MK4 6.5-20 as its brand new. (The NF is, I think, the best bang for the buck). Don't get me wrong, I love the NF and wouldn't give it up. Your certainly paying for everything the S&B offers.
