Posted By: Canazes9 Model 71, 348 Win Help! - 01/07/20
A good friend just inherited a model 71 in 348Win. He asked me for a little help hand loading for it because factory ammunition is scarce & expensive (he doesn't currently hand load). He's looking just to be able to shoot it some, possibly carry on a few hunts. I know nothing about this rifle or the round. Any direction yall can provide for brass, bullets, powders, primers, load data, etc would be appreciated. Additionally any information that he should know about that rifle would be appreciated as well.

Thanks,

David

These were helpful for me when I was looking into the topic. Not much I can add that wasn’t already said in these post. My 71 has quickly become one of my favorites. I used a 250gr Hawk bullet on a moose this year, through both shoulders, resting in the off side hide, 70% weight retention = freezer full of moose meat.

David, I use RL17 with the 250 Woodleigh in mine for 2300 FPS. It is very accurate for using a peep sight. Varget, RL15, H4350, IMR4451, H4831, RL19, etc have all worked fine. I just had a bunch of 17 and it shot well, so that is what I used.

The 200 grain Hornady FP is another great bullet for deer hunting as well. I have bought brass on here and a few other places, and I believe Hornady is making brass for it as well, so that is another option. I use CCIBR2's across the board for my loads in mine.

Yes, and call Karl out at Alaskan Bullets Works, he sells some damn fine bonded 250gr bullets for the 348 Winchester.
Posted By: Angus1895 Re: Model 71, 348 Win Help! - 01/07/20
Awesome thread thanks!

Has any one used superformance?
Posted By: gunner500 Re: Model 71, 348 Win Help! - 01/07/20
I have not, the 348 case has plenty of powder room to get ALL the velocity you OR the rifle want with regular old H-4350 and RL-17 powders, I load my 250's to an easy 2200 fps, they would blow through most anything at a max 150 yard bolt peep range and be easy on the 1937 year model rifle too boot.

If he won't be shooting much, I'd suggest he just buy 3 boxes of factory ammo and rock on.
Isn't Buffalo Bore or similar company loading these? It is only a query as I haven't a 71 anyway. My 86 Winchester is a 33 WCF. Be Well, Rustyzipper.
I thought Starline recently started making brass. The Hornady 200 JSP has been quite accurate for me with IMR-4350. Maybe I'll get lucky and shoot something with it. I'm sure it will kill a deer if I can find one.

I couldn't agree more!
Hell, buy 5-6 boxes!
After he shoots that rifle 6-8 times he will probably rethink the fun part!
And for god's sake, no pointed/Spitzer bullets!
P.s. A 71 348 is my favorite Winchester of all time!
Starline brass is readily available. I disagree with buying factory ammo unless you just didn't want to reload. You can taylor the power level and accuracy for his 71. Well worth it in my opinion.
Posted By: Millerish Re: Model 71, 348 Win Help! - 04/04/20
Once he does start shooting this phenomenal rifle/round, he will definitely regret not picking it up sooner! I I had two lever calibers to carry, small bore would be 25-35, large bore a 348!

The recoil with factory Winchester 200 grain Silver Tips is not bad at all. You will notice it but should be able to handle it. I would definitely recommend he put a peep sight of some kind on it.

I have good results with the 200 gr Hornaday flat nose bullet over 59.0 grains of IMR-4350. My Browning 71 with iron sights give about 3/4" groups at 50 yards, which is good considering my eyes. And I'd never try more than a 100 yard shot with irons becuase I cannot see that well. So this is a fine load for me.

You don't mention if your friends rifle is an origianl Win or one of the newer Brownings. I have read (but not confirmed) that 250 gr bullets are too long for use in a newer Browning. Just be sure to check your loading OAL to your particular rifle
Posted By: Dinny Re: Model 71, 348 Win Help! - 04/24/20
The RCBS 348-200-FN (lead) loaded with 15gr of Red Dot is a good load that shoots accurately and is easy on the shoulder. I plan to HP a few and use them on deer later this year.

Thanks, Dinny

After quite a bit of research, here in the Campfire, Jorge's list, various articles in Handloader, and reloading manuals, I settled on H4350 powder. Using new resized Winchester brass and CCIBR primers, a new lot of H4350 with the 250 grain Barnes Originals and my Magnetospeed chrono, 57 grains gave me 2334 fps, sd-26, es-47. 57.5 grains gave me 2351 fps, sd-2, es-5. I had some loaded at 58 but I didnt even try them, the 57.5 load was so consistent and gave me excellent velocity. Accuracy ran just above 1 inch at 50 yards, with the Magnetospeed on the barrel.

The velocity seemed a bit high out of my 24 in barrel. I double checked the Magnetospeed with my ProChrono and it is correct. Ejection was easy and smooth. Brass looks fine. Rifle was built in 1956.

Now on to the 250 Woodleigh.
