Weatherby Rounds!

[werth338]

I have never used a crimp and loaded most Bee calibers from 224 to 460 with no issues.

S.T. Thanks for the data!

I totally agree with you but try to find High BC bullets with Canelures any more. Most are flat base when and if you can find them.

I still use them when I can find them in some of my rifles but they are for short range use normally.

Like everything else in this sport, I/we have to look at all possibilities when seeking the best performance in a rifle. crimping or not is just one of those.

Completely agree. The possibilities point is why I'm rarely an absolutist when it comes to shooting and hunting. So many things to try and learn.

I was using my ole faithful ( model 94) 30-30 couple of years ago and this was Remington cor-lokt 150gr.and was putting 4 into the magazine.Well,I did the same cartridges over and over for 3 or 4 days,because I hadn't seen anything to shoot.I noticed that one of the bullets had been pushed back into the case neck really far.So even the factory ammo can have a bad crimp.So check your ammo folks.

I bought a newly re-chambered rifle once that had a sharp edge left in it and the case mouth would catch when I chambered a round. It wasn't bad but it was annoying so I set the die to crimp the mouth and it stopped catching. To my surprise accuracy improved, although it wasn't bad to begin with, it was noticeably better with a crimp. It was a large caliber (.366) so it wasn't being used for long range but even though I subsequently smoothed out the sharp spot I still crimp for that rifle.

Keep in mind the Lee Factory Crimp Die (FCD) is effective on non-cannelure bullets. I actually had trouble years ago (46 years to be exact) with my 30-06 pushing bullets into the case under recoil. They were Nosler Partitions and mil-surplus brass. I knew nothing about the FCD and with the pressure relief groove in those old partitions I used the crimp on my old Pacific dies to solve the problem. In reality, those cases had probably been reloaded a dozen times without annealing and I have no idea what the neck tension was. Ah, the innocence of youth.

i know a lot if not most on here don't think you need a crimp on your handloads.....BUT, in the nosler manual and from another buddy of mine, both seem to think the Weatherby rounds do better with a factory crimp on them, the nosler manual doesn't say this for other rounds, so I was wondering if anyone has any experience/advice with the Weatherby reloading and if crimping is something I want to do with them, I shoot a 300 and a 257 Weatherby so it's not like it would be a lot to pick up two lee factory crimp dies. Any info is appreciated

The main reason for a crimp is to keep the bullies in a case in the magazine during firing.

morning, did not the military use a glue or varnish for
prevention of moisture entering the loaded case??

Yes they do, it also will bring up the pressures in a case.

I own a 300WBY and have never had any issues reloading without crimp. As others have said, semi-auto and handguns should be crimped. I think you'd be spending unnecessary money on crimping dies. Hope this helps and happy shooting!

I always crimp my Weatherby rounds. Why? Because one of them is a 378 and the other is a 460. I shoot Woodleigh bullets in both and the bullets are heavy.

Didn't Sierra have strong works about not using a FCD due to bullet deformation? I was kinda thinking of the hunting bullets how many have a crimping groove. Not many. Wonder if dies are designed to give enough neck tension to hold the bullet in place. I came across a lesson about neck tension loading lead bullets into a 300 WSM. There was plenty in that example. Worked my neck expander to get the bullet seated. Looks like die makers may know what they are doing.

It's literally a try it and see job. A light LEE factory crimp makes case tension and OAL less relevant. More consistent velocities, and less sensitivity to minor variations in powder charge, are common.

Just wanted to jump back in and make it clear that if you already have a 3-die set, you have a crimp die. You don't have to buy a separate Lee die...unless you just want to use their particular 'type' of crimp.

I found a crimp worked better for me in all the Weatherby I reloaded. As well as some other cartridges I load for

I have just started loading the 257 Weatherby Mag. I have never crimped any of my long guns loads, ever. I shot my 257 with .55" 5 shot groups with good speed at 100. The SD and ES were not wonderful but the groups, I was satisfied with. Have not changed powders or played with jump yet but for its use, with these groups do t know as I will make that a priority.
