Home Forums Hunting & Shooting AR and Tactical Rifles 77 grain SMK vs Hornady 75 BTHP?

I’ve heard that he is excellent. Buddy has a 224 V and it just drills with everything.

WOA standard barrels are all Wilson and hand lapped, then they have Krieger, shilen, barrels as well.

Okay, thanks for the G2.

Interesting fact about AR Comp - last time I checked, there's only 1 lot (CE0519) of it out there. I heard there was an early lot, but I've never seen it.

The WOA barrels that I have are all the Wilson blanks, FWIW. They don't foul much either, but that's also true of my Craddock barrel & my Kreiger barrel

MM

Have you tried R7.5 primer with that load? It or WWSR MIGHT make a noticeable difference.

I"m not a huge button fan, generally due to shorter life span. That said if you get a shilen from WOP and it won't shoot there is something else wrong.. you can't outshoot a shilen from them. IMHO.

I probably did, and that’s what got me to where I used cci br primers. I have a notebook full of notes..

You are correct I just looked at my ar comp all the same lot bought different times and different stores

My WOA shilen is a picky sob. Probably the most picky mo fo ive messed with, even pickier than my Noveske 3 land, but when you find a load it likes, it shoots damn well.

That is very interesting. I just got back from testing more loads with AR Comp and 77TMK's. I learned a few interesting things about 4 of my rifles..

Ive never seen a non accurate Shilen in an AR barrel or on a bolt gun for that matter. I have seen an inaccurate, to me, Krieger once.

I suspect if you shoot em all long enough you find anything. Shilens sometimes have taken a bit of work, but generally shooters settle on one barrel that works for them and keep replacing with same. That way the load workup is generally minimal.

I hate it each time I get a new gun, you never know what it may throw at you. Just like all my 284 headaches that finally sure look like it was way oversize brass and a size die from Redding that would not size it any smaller. You really never know.

My buddy loves his shilen barrel when he was shooting competition yes ago that who he used and like you has stuck with them. Far as he’s concerned shilen never turned out a bad barrel..

Mine is accurate as hell with the bullets it likes. Accuracy fell off the map with 90 gr game changers though. Going back to the 77TMK, i found it was very interesting that all of my 20" barreled ar's shot faster than my 22" savage predator, while working up loads with ar comp. And another interesting tid bit, the Noveske looked like it had an edge over the others in the accuracy department. This was a first with that rifle. It will be interesting to see how the Noveske does with 10 shot groups and this heavier sierra. I still havent decided whether i want to run a sedate 2580 fps or around 2660 fps load. These are both accuracy nodes for 3 of my rifles. Ill load up more and let 10 shot groups tell me more...

I shot a 1 shot group last night with the 77TMK. Through a 150lb pig’s shoulders from about 75yds. It died. Quickly.

Shot a buddies AR on Sunday that he was having trouble getting it to shoot. Tried 40gr Varmeggedon tipped over TAC, 53gr Varmeggedon tipped Midway factory load, 55gr Speer SP over 25.5gr Lever, 75 Hornady BTSP over 25gr Lever, and 77TMKs over 25gr Lever. The 77s were the clear winner, 3 shot groups under 1” while the 53 and 55 loads hovered around 1.25”. The 75s were about 1.75” and the 40s over 2”. I know I know 3 shot groups don’t mean anything but shooting several three shot groups with no weirdness tells me nothing is seriously wrong with his rifle.

Shilen has a twist fast enough for a 90?

Funny thing we were so stuck on PacNor because they were the only 6.5 twist 3 groove that did what we needed with 90 jlks that we don't have many shilen. I've shot more than I own.

I'd not be afraid though...

And before pac nor we were Krieger fans.

But then again I know a few times civilian Perry champs, both male and female that shoot only shilen... LOL. That means they beat me because I never was a champ at Perry.

Its a 6mm. I was hoping so, but not the case. Do you know the twist rate of your 6WOA, and which bullets does it prefer. It seems almost pointless to just top out at 85 grains, when all of my 223/556 ar's run 77's so well.

Good intel. Thank you. 77 TMK's and LVR have been working for me and a pards rifle so far. The 75 HPBT's aren't nearly as accurate, but they load easy and I have a bunch so were burning them up for 100 and in stuff since the zero works fine there.

What kind of velocity are you getting with the 77TMK load? I'm in agreement about 3 shot groups and also agree with rost on the subject. If you see something really weird like 2 close together and the other one 2 inches apart, theres no reason to shoot 5 shots into a group. One thing that I see about your loads is its not developing a load per se, so unless your buddy wants to spend a little time actually developing a load for his rifle, he's likely never going to find something that really shoots well in his rifle....When I go to the range and develop a load, its with 1 bullet and maybe the few rifles I want to test that bullet and load with, then I work up. Start with a number from the book where you think you might be able to live with the velocity and go from there. With the little .223 rem case, I've gone as far as .2 gr. jump in charge wt. with each load. With all of my bigger cartridges, its the norm to increase charge wt by 1/2 a grain each time... That and the use of a good chrono, is the best way to find the accuracy nodes.. There's also ladder tests, but its best to shoot those at 300+ yards so you can get a better picture of what that bullet/load is doing... What I see with your post is you are out there shooting for fun. Nothing wrong with that. Just not the way I do it. I first get down and serious when developing a load, then after that, it's shoot for fun and post up some of those results in the challenges here or compete with that load.... However, life would be a simpler place, if we just called 3 shot groups good enough. Some do, some don't....



Usually when I have a good load dialed in and I'm shooting 10 shot groups, the first 4, at least, go into the same hole. Thats when you know you have done your due diligence in finding the best load with the powder you are using for that particular bullet and components...
