6.5-47L 140 vs 130

[4xforfun]

Just going to order up some components for my new project.....6.5-47L....new to me. Main goal will be 1k BR. 30 inch Krieger 1-8 Twist 4 groove. Did a little playing around on the computer and see that it is baisicly a wash in FPS and drift at 1K using 2800 for the 140 and 3000 for the 130.

What are you shooting?
Why?
Did you try both?

I have some 140 Target VLD and 140 Hybrids on the shelf....just wondering if it is worth trying the 130 class pills.

GO!!!

i don't shoot 1k BR but hunt to 1k and tried 120-130-136-140 and can shoot them all! i use 140 orange box and everything i shoot is DRT! lots of whitetail to 550yds speedgoats to 655 and 855. Excellent Super Performance hunting bullet should be on the box!

my personal thought is tune the heck out or the 140's and save your barrel for that and matches. I didn't gain anything by trying the others but the fact the 140 beat them all in group size in my gun when ever i tried them.

8.5tw and @2850fps of course CCI450 and H4350

Here's your 130 Bergers from 1000 15 rounds fired:

In my RBROS 6.5x47 I run the 130 Bergers just under 3000 fps. These are the hunting version. I’ve never tried any 140’s because this load has shot so good. Kills whitetail like lightning. My other x47 is a light weight built off a Remington 700 action. It shoots the 130 Accubond at 2900 fps. Again it’s total devastation on whitetail.

MY 6.5X47 SEEMS TO LIKE THE BERGER 130 BETTER THAN THE 140'S AND OF COURSE THATS WITH CCI 450'S AND H-4350 AT 2900 NODE AND IT SHINES !!!!!

I put all my eggs in one basket and went with a .198" FB with the intention of shooting 140 Hybrids at an upper node and the planets aligned. If 130's shot this good I would have no problem shooting them either. With your barrel length and depending on FB you might be running the 140's a little faster. Mine shot great at 2780, sub 1/2 moa all the way out. Then I put the coal to it and it like some pressure approaching max. I couldn't be happier with it, current lot of H-4350 I had to back off to 2880 FPS.

Frebore will be in the .168 range....can't remember the exact #.

I have switched for this season at 1000yd matches from a 6 BRX to a 6.4 x 47. If you look at the ballistic tables in order to gain a wind advantage at 1000yds you must be shooting the 140 class bullets at around 2800 to gain a few inches advantage over a 105 class bullet at 2950 in a 6mm bullet. You will add some recoil which is a factor if you shoot free recoil with like I do. I use a tuner not compatible with a muzzle brake so I am interesting to see if the small wind advantage I will gain will help me in matches. All that counts is "scoreboard baby". For these reasons I have ruled out the lighter 6.5 bullets.

Playing with my I6 program.....the 130 VLD at 3000 is better in the wind than the 140VLD @ 2800....but only by a fraction of an inch. I'd say...according to the program, that the wind thing is a basic wash, since the velocity could go either way 50 FPS with either bullet. I figure that the results would be the same if i were to compare Hybrid/Hybrid.

I can get a pretty good idea about the exterior balistics with a computer......just wondering which one shoots the best at 1K.

Thanks for the replies,

your comparison is not exactly an apples and apples comparison according to one of litz formulas of comparing what velocity you should be able to get out of bullet a (130g) vs bullet b (140g) in your case if your able to get 3000FPS with a 130 in theory that would be the equivalent of 2890FPS with a 140 class bullet. Re run you ballistics app using that.

Just to throw a wrench in the works, the Australian 1K record was set with 123'sI know other records were set with 130's and 139's a search of this site should turn up a few.

I am talking EXTERIOR BALISTICS......you are talking about INTERIOR BALISTICS. My using 2800 and 3000 is based off of actual FPS reported across ALGORES INTERWEB......where people are getting the best accuracy. Obviously I am not using hard FPS data as every bbl will be different. My point is that it isn't a big enough difference between the two to base my decision as to which to shoot. Kind of like why I shoot the 108 BT vs the 105 Hybrid...with some success I might add.

My accuracy load with my 6.5x47 with Varget was 2910 (37.7g). My barrel went south quickly at that pressure (1500 rounds), so barrel #2 I loaded with H4350 at the 2820 fps node load for my F-class rifle. This allowed me to get more rounds out of that barrel (1800), but I do not think that load shot better than my 2910 fps load. I think if you ask people which powder they are using for the 140s, if H4350, then it will be around 2820 fps, if Varget/RL15, it will be much higher velocity. If I were shooting a 6.5x47 for LR Benchrest, it would be 140s with Varget at the 2910 fps node.

I plan to revisit the 6.5x47 this year and I will see if the 2910 fps load with Varget hammers, if so, I will shoot it there.

8.5 twist 4 groove 26” Krieger. Berger 130 gr Hunting VLD jammed 0.015”, 39.0 gr Varget , CCI 450 is magic at 3010 FPS. Shoots sub 1/4 MOA at 600 and 800 yards in the dark with night vision btw. Tried 140 gr Hybrid but didn’t seem to have as much potential but in all fairness didn’t give it near the chance due to twist calculator saying it was marginal.

I’m on my second 6.5x47 Barrel and I tried 130 VLD’s at the beginning with my first one and abandoned them quickly after the first group 5 shot group I shot at 600 with 140 Hybrids was under 2”. I shot 2500 rounds out of that barrel and it did well. I’m 38 rounds in on my new barrel with 140 Hybrids and of the five 5 shot groups at 600 Yards with them my agg is just over 3” I have just found the 140 Hybrids flat shoot and for my needs they are great. I’ve heard great things about the 130’s but the 140’s are what I’ll be using for the foreseeable future in my 47.

 

[JBT47]

Shooting 140 Hybrids at 2915 (40gr Viht N550) and 130 Hybrids at 2950-2960 (41.5gr H4350). Results at 1,000 yards are very similar. Both loads are very accurate.

You already know the answer Todd. Let your barrel and the target tell you. Acurracy trumps!!
