The guys on his team also use the same load....found out later they won, their name is "Team Hornady".....go figure, The only reason I am trying the 77SMK is for the "magazine" length. I plan to run a measured crimp pressure series on these starting with no crimp. 0000003224 00000 n Another benefit is reliable feeding in magazine fed firearms. Some guy's are unreal with a set of iron sights at distances that can make you dizzy trying to concentrate on the target. 0000001356 00000 n Im a relatively new reloader with only 15 years of experience compared to othern on here that would have 2 times that but I see this question so often on this & other forums that I take the same option with all that everyone asking the question is after the 'magic pill' solution!

Hodgdon 223 data shows the 23.7 MAX.

He shot a MOA at 600 with his "Service Rifle" with "Match" sights. Sierra data for 223 shows MAX of 23.9 Varget using the 77 gr HPBT but their test firearm is a 20" 1 - 7" twist.

These help you to keep from popping primers when running hot loads.

I'd use the Hodgdon data starting low and working up.

0000001007 00000 n I have this info somewhere....I remember reading about it and actually looking at a chart. 0000013903 00000 n Nosler data shows 24.5 Varget as MAX on their 77 gr using 1 - 7" twist also. Clear editor.

I don't want to get into pressure problems either. Using bullets from Nosler BT, Sierra SP, Speer SP, Sierra HP, Hornady V-Max, Sierra HPBT, JLK VLD, Sierra … Kiwi, My Tikka likes 24-25 gr of Varget or RL15 with the Nosler 77 gr CC bullet. It sounds scary.....but Lyman says you can do it, its in their book! I am using 25.5gr Varget with the 69gr SMK and 24.5gr Varget with the 80gr Berger.....they both make a crunching sound when seating the bullet. OK...preliminary results are favorable. I immediatly went to the 400 yard bench. Hey guys, I have Lee and Hornady loading books, just curious about Sierra TMK SMK bullets in the 70 to 80 grain range for 223. 0000001789 00000 n 223 Remington (AR-15) 28 grains of Varget will not fit in the case without vibrating it! Upload or insert images from URL. I can get out to 450 yds where I shoot. We do however seem to have several Service Rifle guys that come to shoot, but none of them use the 77SMK. Range to target was 130 yards. The first two shots I pulled, the 3rd and 4th shot's in the same hole and 5 went at the top of the 3 and 4 hole....considering it was 8:20PM and "sprinkling" I am happy.

Just a note so you don't get into pressure issues based on your chamber. 0000008101 00000 n You can post now and register later. He was using the 80gr AMAX and 24? I am ideally looking for a load that will give me 1/2 MOA groups at 400 and 600 yards, but I am willing to start from scratch if I have to. × I thought I had it with the 69gr SMK, but they seem to be greatly affected by the wind, I can't believe how they move around.

Hodgdon 223 data shows the 23.7 MAX. Course. This is all good stuff to know, glad we are talking about this stuff.

I'm picking up another torque wrench next week to try higher pressures. I haven't had the opportunity to test the Noslers at longer ranges but it is on my "to do list".

Looking for powders, if anyone could help me out, I would appreciate it.

In my ongoing quest to master (chase my tail) with the AR at 400+ yards I am wanting to try the 77 grain Sierra Match King loaded and seated at "magazine length". 0000003246 00000 n %PDF-1.4 %���� Have you tried this load without crimping? Hodgdon's website has a load for .223 for the Sierra 63 grain SP. I have no experience with doing this in magazine overall length but we do use Varget when we use the heavy pills to shoot from 600 to 1,000, we just load them single, and they are very compressed loads to say the least. To qualify this load I shot 5 rounds at 100 yards to start out. Sierra lists the 65 and 63 grain bullets together in the same table sharing the same data. If it does, how do you find data for a different barrel than that used for the data development? 0000009403 00000 n 0000001080 00000 n

I don't want to get into pressure problems either.

You also want a harder/thicker primer such as Rem 7-1/2, CCI Br-4 or 41 or any brand Magnum primer.

Kind of funny seeing an Aussie bust the chops of a Kiwi (assuming kiwi refers to being a New Zealander). It averaged 2600 fps. Hi all, I've recently purchased some Sierra 77 TMK's to run in my suppressed T3. For a better experience, please enable JavaScript in your browser before proceeding. Can anyone help with their own experiences with this loadout. For shooting at 600yd we use either 69,75,or 77gr bullets but for 1,000 it is 75 and 80gr.

I will try your load for the 77SMK at mag length. My "go to" powder is Varget, I use it on everything from the 40 grain V-MAX to the 80 grain Berger.

Interesting.....My Lyman manual says 25 grains MAX of Varget...I will check into this. Just the information I was looking for, thanks guys. 0000001584 00000 n

23.7gr Varget is the noted MAX for a .223 chambered barrel. 0000024926 00000 n The trick is to use the correct size target for the specific distance. I am a little familiar with Bill Wylde and I think Rock River uses his 223Wylde chamber. I have had great success with the 69 grain SMK and the 80 grain Berger VLD. .223 Remington (Hodgdon CFE 223 Data) reloading data with 26 loads. Sierra data for 223 shows MAX of 23.9 Varget using the 77 gr HPBT but their test firearm is a 20" 1 - 7" twist. Some guy's are unreal with a set of iron sights at distances that can make you dizzy trying to concentrate on the target. At 24.5 gr of Varget, I got (0.944 MOA) at 2730 fps. I was impressed with his ability. Some rifles like it and some don't. Hope you can find that and share the information here.

The twist and barrel length realy only have an affect on velocity and bullet stabilization, which are both critical when pushing a .223 bullet past 600yds. I always assumed the chamber geometry would have more to do with it than barrel length and twist. trailer << /Size 92 /Info 57 0 R /Root 60 0 R /Prev 137735 /ID[<4e74c94a871dab1d19028121db5c1b6d><31b373a22a682a1c329cc79c03e6223e>] >> startxref 0 %%EOF 60 0 obj << /Type /Catalog /Pages 56 0 R /Metadata 58 0 R >> endobj 90 0 obj << /S 201 /Filter /FlateDecode /Length 91 0 R >> stream Penetration was over a foot from a rear quartering shot into a 170 pound deer.
