270 in a 7400

[jimbo1096]

After reloading straight wall cases for 40 years I'm expecting to start soon with the .270. Am open to any suggestions, powder, favorite loads and components, or problems to be aware of. Have the dies and some cases, a box of Speer 150gr BT bullets, but no primers yet. And need a shell holder if anybody has a spare.

Edit to add- I believe I have found by reading online, the 45acp to be the same shellholder to fit the 270win. If that's so- I'm good to go!

The powder that has always been good for me in .270 WCF is IMR 4831. Am sure H4831 would be good as well.

My .243 loves IMR 3031, but I've never loaded for .270.

With 150 grain bullets in the 270 I have had success using four different powders in different guns. H-4831, RL-22, IMR-4831, and Acurate 3100 have worked in different rifles. With 130 grain bullets I have never got past H-4831 as it has worked well in every rifle I have tried. I've never needed magnum primers and I have always found maximum loads to work best. For deer and antelope I use 130 grain bullets and for elk I use 150 grainers.

Thanks for the tips, I'll start my research based on the IMR4831 If it is available locally.

I use IMR 4831 as well. I also agree a 130 gr bullet is good for deer. Bigger game, bigger bullet.

Without me going to look it up,,, I believe I too use H4831 as my 270 powder. Then,, the 130 grn bullet is the Jack O'Conner standard. I've never seen any reason to change that either.

I've used RL19 and H4831SC in the .270, I prefer RL19. Its also recommended you stay further from the Max load than in a bolt gun, due to the 7400s design. Its perfectly safe for published loads, just don't exceed them. Also, you'll need to full length size the brass, but you won't need small base dies.

Thanks for the replys and suggestions- Still looking for powder locally. Not many outlets, may have to go upstate to Bass Pro Shops, but they get expensive.

When working up loads, bear in mind that gas-guns aint bolt guns. You got other things to consider there than just chamber pressure.

What powders do you have. The 7400 is a middle of the road type rifle. I had one in 30-06 and it tended to like combos that were middle of the road in powder burning rates and such. If you have some powder that will work then I suggest trying it before buying any others.

 

[jimbo1096]

All my powders and for shotgun or handgun.

IMR4064 and IMR or H 4895 will be safe for that gun and the .270. You won't get maximum pressure or velocity, but you won't risk hurting the gun either.

I will speak to the gun, more so than the caliber or load. Case sizing has to be right on the money for an autoloader and I would recomend chambering unloaded and sized cases to check their fit. A bolt gun can close on a poorly sized case due to the camming action. A pump gun can be closed with some force but still be temperamental. An autoloder is in a world all it's own when it comes to reloaded ammunition and as DGW1949 stated, the gas operated guns don't take too kindly to hot loads.

I'd agree and would also add Re12 and also Re15 at the slowest end. The Remington autoloaders as well as BARs are some of my favorites and I try to get good life out of them and tend to shoot them a lot. Using a powder like Win 760 or Re19 even at starting loads can produce noticeable wear in short order on those Remington actions, at least from what I've observed in the '06 class cartridges in those rifles (I've not seen this in the 750s yet, not sure if they've worked it out or they just haven't been around long enough).

Have fun!

ps. I'd also agree that you don't typically need the small base dies for that rifle, especially if kept in good condition. I do have a couple of the older autoloaders that I do neck size for, but I use middle of the road loads and keep the brass clean and in nice condition. I typically use this for light for caliber bullets with medium rate powders and I wind up keeping the velocities very consistent and they work out nicely as very accurate varmint rifles.

The 7400's in .270 that I saw trashed were using hot loads with (?)4831. Combination of heavy loading and high residual and port pressure resulted in jerking the rim off and/or breaking the extractor. Just my limited experience.
