Help with .270 Reload

[Zeke-BE]

With the last year ammo scare I was forced to reload. So Im pretty new to it. But Im shooting the Nosler 140 grain accurbond. I've been also practicing lot more with Long Range shooting and hitting 500-650 yards. I know 500 yards is not long range to some but Im getting there. But I want a load that when I hit a deer at 600-700 yards I will at least have over a 1000 lbs of energy when I hit it at that distance. To get that lbs I need to be shooting 2950-3000 fps. I finally maxed out the load that says in the Nosler book and shot them today. Here are my results

 

RL15, 47grain, Fed 210 primer= 2,690 fps

IMR 4350, 53.5, Fed 210 primer= 2,525 fps

RL19, 55g, Fed 210 primer= 2,678 fps

 

This is no where near 3,000 fps in what the Nosler book is claiming. What im I doing wrong or need to change? Im shooting a Tika .270 24" barrel and I believe 1-10" twist. Go easy on me Im still learing in the Reload world! Also its not my goal in life to shoot a deer at 700 yards I just want to make sure that Im capable of a go shot placement and knock down power if I have to. I have a mule deer hunt in Nov. in 36B

Im a little new at this too. So far my best groups at 100 w/ r 19 . And 140 gr. Sierra bt. 56.5 grns. Cci 200 primers are 3 shot 3/8inch groups. No chrono. Yet . I have several calibers loaded for an oct. 4-5 shoot. Probably doesnt help , but who knows?

If you can get any Reloder 22 I find that gives the highest velocities in my .270.

I'm shooting a 150 grain Nosler LRAB out of my .270 at 2980 fps. 52 grains of IMR 4350, cci large rifle primers, Nosler brass.

I will have velocity after next weekend on my loads.

That's fast, what barrel length?

Here are my two loads for my .270Win

Interarms Mark X w. 24" barrel

 

140 Berger VLD

58.3 gr. RL22

Winchester brass

CCI BR-2 Primers

.0050 from lands

3075 FPS @ 95°, 1563' AMSL, 29.90 Baro

Shoots just under MOA

 

150 NAB LR

57.5 gr. H4831SC

Winchester brass

CCI BR-2 primers

3.5535 COAL

2900 FPS @ 85°, 1563' AMSL, 28.85 Baro

Shoots .254" 5 shot groups

 

140 Berger VLD

At similar altitudes/temps to sight in above will retain 1000 ft/lbs of energy at a distance of approximately 801 yds.

7000' AMSL and 40° will retain 1000 ft/lbs of energy to about 622 yds.

 

150 NAB LR

At similar altitudes/temps to sight in above will retain 1000 ft/lbs of energy at a distance of approximately 962 yds.

7000' AMSL and 40° will retain 1000 ft/lbs of energy to about 745 yds.

Word of advice on RL22, it is very temperature sensitive. My 300ultramag tejas likes 96gr when its below 50 degrees. Pushes a 168gr berger about 3650fps. However when it was 100 deg in casa grande 3820 with primers buldging and bolt sticking was a little scary.

First place I'd look is COL. Could be too far off the lands. Some rifles have really long throats. All of em are a little different. It can have drastic affect on your velocity, pressure, group size, etc. What the book says doesnt mean much. Lark.

I would double check the calibration of your scale?

I like the Superformance powder for the 270 Win. I can get 3050 fps from a 22 in barrel using 140gr TSX bullets and 58gr of powder. You should be able to get to 3100 fps with out much trouble out of a 24 in barrel. Accubonds are excellent bullets. Start out low and work up. A reasonable start would be 55 grains and work up. If you have a chronograph you will be able to know when you reach your 3000 fps threshold. Superformance is very temperature stable, and groups very well when you have the right COAL. A competition bullet seater die, Hornady bullet comparator and calipers are a must in achieving tight groups. To shoot at those ranges you need loads that group between 0.5-1.0 in center to center at 100 yds. There is a very useful bullet trajectory calculator on shootercalculator.com. Superformace powder has the same burn rate as H4831 but adds about 100-150 fps higher velocity. Have fun an let us know how you are doing.

What chrono are you using?

[Zeke-BE]

Predator I'm using Chrony. But I think it's on! I also tested it out on my brother factory Winchester round that stated it was shooting 2850 fps. I punched a couple through my rifle and Chrony was saying 2805 fps.

Have you checked your powder scale?

Have you checked your powder scale?

 

I use my buddies electronic scale. Then we would double check it with a. Manual scale.
