new to reloading and need some pet loads for 140g berger bullets in a 270 winchester.
I'll double check when I get home tonight to get you the exact specs but I believe the following will be true:
60.2 gr of H4831sc
recorded muzzle velo of 3005-3030 w/ 24" barrel
I've shot this load out to 1090 yards on a metal plate with great accuracy. Deer, antelope, and prarie dogs haven't liked it too much either.
Like I said, I'll double check that tonight and edit the post if incorrect.
60 gr 4831sc
Fed GM 210M
3070 fps 26" barrel
Consistintly shoots 1/4" groups
I shoot the 150's, but my rifle also likes H4831SC the best, also tried RL 19, IMR7828SSC & IMR 4350. I use F215M primers.
3,000fps should be fairly easy to get. My 150's are at 3k fps.
Also I tried the "Jump Test" for seating depths. I tried .010", .050", .090" and .130" (these are all distances from lands, on my hunting rifle I didn't seat any into the lands). My stock Rem700 preferred the .050" jump the best. You may be limited by mag length on this. But I think it's worth testing, the different depths produced largely varied accuracy and SD's.
My rifle also prefers the .302" bushing for neck tension(Win brass, unturned necks).
I started out with the 130gr VLD's but didn't have enough neck to seat them close to the lands, so I bought some 150's and haven't bought another bullet since then.
The Berger's are very accurate and have proved devastating on deer.
Stalker I am also shooting a 700. What is your powder grain and oal on the 150's.
I found that the IMR4350 at 42-43gr worked great with the 140's and RL 22 at 60-60.5 worked best with the 130's. And both of mine are loaded well off the lands and shoot .25" or better.
You would need to work this load up in your own rifle because its over max

Whats your speed with the 140's?
2995 out the muzzle and thats 3.360 c.o.al.
Just picked up a .270 two days ago and shot it for the first time yesterday. I literally went to my " go to" manual and picked out two loads using two powders and two bullets. I chose 140 Berger VLD's and Barnes 130 TTSX bullets. Well, the gun,( Browning A- Bolt) didn't like the TTSX as well as the Bergers. Long story short. 54.0 -RL19-140 VLD using fresh Federal 210 primers yielded .3 groups at 100, and groups in the .7 range at 200. Now I am not a fluent .270 man, I have always favored the sevens and thirties through the years, but this gun , load combo works. I have not chronographed it yet, but will soon. I beleive my COAL was around 3.336 plus or minus. It seemed to be fast,as I was seeing impact at 200 PDQ when I was shooting at that distance. I have not had that much experience with a .270 in the past, but it is enlightening to have one that shoots without a whole lot of fuss. Hope
This helps. AIM SMALL, MISS SMALLgun) 7STW.
