Home Forums Hunting & Shooting Ask The Gunwriters What premium bullet/load to get .270 Win 140 gr. to 3,100 fps safely with 24" barrel?

15,000+ views & less than 75 responses. Amazing.

Three year old thread and still not resolved. R26 is my new go to for medium sized cases .243 to 300 WM. Follow MD's advice and you will find bliss. I can get there or close easily with a 24 inch barrel and R26. Many are reporting good velocities but not exceptional accuracy. I think the potential is there, treat it like a slow or ball powder, try magnum primers and it seems to like the sticky bullets or those with a long bearing surface to even out pressures. I am not picky and usually quit when I consistently get groups of an inch or less. Others may be more picky but I don't shoot anything but rocks at extreme ranges.

3000 fps will kill an animal just as dead. Get a short mag or a Weatherby if you feel you just have to get 3100.

I agree with this. My two 270's right now are clocking at 2825fps with 58gr. H4831SC using 140 Acc's (RAR). The Kimber Montana with the same load is 2865fps. I see no need in chasing speed when its consistent accuracy at acceptable pressures using an adequate bullet is what you need. If the number "3" is what someone needs, then move to the 270WSM or a 270Wtby..

Damn, i don't know, but will happily continue to use the old standby load featuring a 150 gr partition at an easy 2925 fps, it's a no nonsense, accurate, hard killer for white tail deer, I swear I've seen buck deer in the scope close their eyes winching in pain when being hit by that load.

JB,

I was just headed to the reloading bench to load a batch of 270 140 TTBCs for a late season mule deer hunt when I happened on this thread - very helpful. I had a couple of boxes of the old Federal 140 TBBCs (non-tipped), but I went through them in the last few weeks to test the rifles I'm considering for the hunt. Now I need to find a load that will get me close to the Federal factory loads.

What primers did you use for the max H4831SC loads? Are you confident about the temperature stability of H4831SC in this application? I'll be doing the load development and test firing in the low to mid-80s F, about 1000 ft. elevation and shooting them on the hunt at about 5000 ft. elevation and likely in the low 30s-40s F, so the temp differential may be an issue with high end loads. I plan to use your data to get a start on the chrono sessions for this weekend - thanks!

Wildcatter,

H4831SC is among the most temp-stable powders available, so there are no worries there. In .30-06-sized cases like the .270 it's also easily ignited by standard primers; I used CCI 200's.

^^^^

I'm getting 2950 fps in a 22" rifle and 3050 fps in a 24" rifle.

58-59 grains of H4831sc, 140 Accubond and CCI 200's.


I have tested them down to -20F. Lost some velocity but not as much as other powders.

Thanks, JB

140TSX and Ramshot Hunter gets me 3050 in multiple 22" 270's. Never tried/chrono'd it in a 24".

Friend of mine showed up at the range with a new Mossberg rifle in .270. I believe it has a 22" barrel.

Ran some Remington "Hyper Sonic" 140 gr ammo over my CED chronograph for an average of 3104 fps!

I was impressed. Accuracy was decent too.

Guy

Remington ??.....CED ??....... 3104 ??

What did you do ? Shoot 2 and ADD together ?



I am impressed being Remington. That's certainly different from what Rem used to do.


Jerry

try rl 26.its the new kid on block.shoots great

Ya, I added 2+2, which even today seems to add up to 4

Then I added 3100 fps!

New shooter wasn't impressed, Didn't know 3100 fps was FAST. I was impressed...

Guy

My results exactly this weekend. 58grs in a Remington case got me 2951 avg out of a 22 inch Pre64 M70.
Also shot 3/4 inch groups off of a rolled up jacket since I forgot my rest. I like it.

130 partition and 4064

Frankly, I don't think it's all that important to hit a 3100fps threshold, but then again, my deer aren't that hard to kill, apparently.

For years and years, I used 4350 and 130gr. bullets, shooting at a bit over 2900, and killed deer without a qualm or wiggle.

I only switched from 4350 to H4831SC to be in the "cool" crowd, got a 100fps boost over what I was getting with 4350, except it's noisier and kicks harder. Kills stuff real dead, but not more dead than I was killing them with the slower loads. I even tried some 140s for a couple years, and they didn't kill deer any deader, either. After all, dead is dead, no degrees of dead, just plain old dead.

I guess, if you gotta have it, you gotta have it, but you won't need it.

Dead is dead.

You are right dead is dead but keep in mind velocity is tied to exterior ballistics. Significant over distance.

I,m learning that every rifle is different. Just got a new Sako A7 last week in 270. The loads that were ok in the
Vanguard are to hot in the Sako. Have to back of loads 1 grain. Had no trouble with extraction or primers but
velocity was to high. Had a similar problem with 2 7MM mags, one rifles velocity was 150fps less than
the other with same load. RL26 seems to be the safest powder to use. Also RL23 is very accurate in both my rifles.
With 140gr Accubonds, best load was at 3080fps. you can get 3100fps or more but load gets very compressed.
