I am using 25.5 grains of BLC-2 for Prvi and Nosler 69 grain BTHP bullets and this works extremely well out of Lake City NATO brass.

I hand weigh each load.

For the Hornady and Prvi 75 grain BTHP I use 25.0 grains of BLC-2, as well as for the Nosler 77 grain BTHP.

I don't see why not. Why don't you give it a try?

 

[SkyPup]

That sounds great, I'll be looking forward to your results.

I have not fired my rifles at anything over 300 yards to date.

One rig has an Eotech 512 with 4X Magnifier and the other a Burris XTR 1-4X scope so I think that is about my limit.

What kind of scope are you using?

 

[SkyPup]

That is a nice scope.

I ordered a Redfield 3-9X for my Thompson Center .223 with a 20" barrel and 1:8 twist, haven't got the barrel or scope in yet, still waiting, but it should be a sweet setup once I get it all together for long range shooting with the heavy OTM bullets.

Wow, that is very interesting data for sure, seems like Varget is the way to go in your rifle but the BLC-2 @ 25.6 grains was not bad and the velocity was up there. Looks like the chronographed velocitys are very nice too, thanks for posting that as I do not have a chrono.

I just picked up some Sierra MatchKing 69 grain BTHPs yesterday on sale at Gander Mountain, so will try them out and compare them to the Nosler, Hornady, and Prvi 68-69 grain bullets. I'll stick with 25.5 grains of BLC-2 for all three of them in new Lake City brass.

I also just ordered a Redfield 3-9X 40mm on Burris Picitanny mounts so I can swap out my Burris XTR 1-4X scope to a more high powered scope on one of my SIGs for longer range precision shooting. With a 1-4X the best range is anything out to about 150 yards or so. When I get the 3-9X mounted and zeroed in, I'll post some photos of my targets.

My friends bring me once fired .223 PMC, .223 Prvi, and .223 Winchester sporting brass from the range that I recycle into my practice reloads all the time.

But I bought 3,000 new 5.56mm NATO Lake City '09 brass cases from Wideners for precision reloading at full power:

I'll be looking forward to the ACOG review too!

 

[SkyPup]

Wow, that is totally awesome! 8)

Glad to hear those loads are working out well. I will get to work and load up some Nosler and Sierra 68 grainers and try them out target shooting from 50 to 200 yards.

I just ordered a nice Hornady Lock N' Load Concentricity tool from Sinclair International. They had a nice review of it in this months NRA American Rifleman magazine:

http://www.americanrifleman.org/ArticlePage.aspx?id=2249&cid=10

I'm going to go over my reloads with it and see how well I have been putting things together!

Thanks so much for the update. That 25.5 grains of Hodgdon BLC-2 behind the 68-69 grainers sure gets the job done!!

Do the Redding Full Length Dies have a carbide case neck mouth expander plug in them so that you do not have to lubricate the case mouths?

That is the one thing I hate doing with my RCBS set.

When I get the concentricity gauge, I'll go over my my stored up reloaded ammo and see how well I've been doing.

The Hornady Lock N' Load Concentricity tool is a nice addition to my reloading tools.

I went over about 300 rounds of my 75 grain Prvi and 75 grain Hornady reloads last night as well as some Sierra MatchKing and Prvi 68-69 grain reloads and some Hornady NATO 5.56mm T2 commerical rounds.

All of my 75 grain reloads were in pretty good shape, most were 0.002-0.003" off, although a few were visually maligned up to 0.005-0.006". Adjusting them back to around 0.002-0.003 was no problem.

You can look at the cartridge as you turn it in the tool and tell visually if it is more than 0.002 to 0.003" out of alignment just by looking at it.

The 69 grain bullets were even better, with some right off the bat being 0.001" or less concentric.

The Hornady rounds were not any better than my own reloads.....

I will check out some XM-193 and M-855 NATO loads and see how them measure up to my reloads.

This is a nice tool!

I went over about 300 rounds of my 75 grain Prvi and 75 grain Hornady reloads last night as well as some Sierra MatchKing and Prvi 68-69 grain reloads and some Hornady NATO 5.56mm T2 commerical rounds.

SkyPup, Where are you buying your Prvi bullets for handloading?

I've been getting them from either Graf's or Widerner's, they both have them in stock now.

P.S. - Here is another review of the Hornady Lock-N-Load Concentricity Tool

http://gunmart.net/accessories_review/hornady_lock-n-load_concentricity_tool/


I really like this tool and in addition to my handloads, it works great on commercial ammo too, which is something I did not even think about when I got it. But commercial ammo is far from perfect too! :wink:

 

[SkyPup]

After going over 550 handloaded rounds the last couple of nights with the ConcentricityTool, I have found that 9 out of 10 of my reloads are within the 0.002-0.003 specification.

However, about 1 out of 10 was anywhere from 0.004 to 0.008 out of range, which I easily corrected with the tool to put the shell back into spec.

Also, just doing a cursory examination of a couple of boxes of commercial brand new .223 Hornady 75 grain, Prvi 75 grain, 5.56mm Federal XM-193 and 5.56mm Winchester M-855 rounds, I have found defective shells in approximately 2 out of 10 cartridges, which I also was able to correct with the tool to proper spec.


Even if you do not reload, this tool can improve your commerical or mil-spec ammo too.

My SIGs definitely shoot the 75 and 77 grain OTMs better than the 68-69 grain ones by a factor of 2:1.
