Need help with 450 Bushmaster loads.

[Slash2]

This thread is definately the best resource for the 450b on the net. THe only problem is that actually getting the info out of this thread can be a pain in the butt since the only way to do it is by reading the whole thing.

So I'm wondering... I have some webspace that I have not been using and could set up a dedicated 450B forum, but it wouldn't be any use unless those of you here that have done so much wanted to drag all your testing, tips, and data over to the site, would you guys be interested in this?

I don't anticipate the forum being a high traffic madhouse just because the 450b has a limited user base, so it wouldn't be hard to run.


Whatchoo guys think?

Hey, I bet it's easier for people to read the whole thing than it would be for them to go it on their own!

But I know what you mean MudBug by it being a pain in the butt, I've gone back through the whole thing a couple of times just to find something one of the others had reported.

What I would like to see is a compilation of the information that's been posted with a wikipedia twist, people able to add to and edit information as we learn and grow.

Is that possible, is that something you could put together?

[Slash2]

Sounds Great but I'am new and have little to add.

I just got my second AR it's a 16in. 450 bushmaster on a Rock river lower

2 stage trigger.

This thread is very good the best I have found. and your right it's hard to

find the right information with out reading it over and over!

I want to work on 200gr JFP .451 loads to keep cost down.

I will add results as experience increases.

For what it's worth, I did some playing with 200gr encapsulated SWC's using LilGun.

43grs, avg fps 2483
44grs, avg fps 2495
45grs, avg fps 2542
46grs, avg fps 2587

2-4" groups

I'm curious how much bullet jump you guys have experienced so far?
Earlier in the thread I read of a modified Lee FCD being used to place a solid crimp farther back on the case. How has that worked out?

I get very little bullet jump now that I've been adding the secondary crimp to the Barnes bullets.

I've got a couple of other questions as well. How high above the bore are you mounting your optics?

My scope is a full 2.8" above the bore. I think I need lower mounts!

How is brass life, particularly for you guys who are pushing the envelope a little?

My brass has held up well over 10 reloadings each, in fact I haven't had one split or fail yet, but I am wondering how the crimping is going to effect them.

And how are you dealing with recoil? I'll need to add a little length of pull to this rifle. I shoot my HP AR with my nose right on the charging handle. I suspect that's not gonna be a smart plan with the .450B. Any good experiences with a particular recoil pad?

You do not want your nose or eye any where close to a solid part of the gun. My current scope has 5" of eye relief, that's plenty. My earlier scope had about 2.5" of relief, it and my eyebrow met a couple of times. My stock has a .5" pad on it. I only begin to see the pattern on the back of that pad imprinted in my shoulder after about 70 rounds.

Thanks Slash2

I have some W296 on hand I'll try it with 200gr JFP Montana gold bullets

will let you know how it works.

I may be able to add some kind of Wiki functionality, not sure yet, but I was thinking of a reloading database, a "Tips and tricks" section with "What worked" and "What didn't work" subsections so people could see what has been tried. Things like that.

[BD1]

Slash,
What are you using for the "secondary" crimp?

Jeez, this tread needs an index!

For secondary crimp see page 37-50.

Also search this thread for crimp.

[BD1]

Thanks Slash, This thread does need an index. By the time you've read all the way through it, it's tough to remember where along the way you found any specific thing.

Slash, My Lee 45-70 FCD arrived today. How did you get the collet out of the die to shorten the crimping section?

BD

[chestpubes2ballfro]

hey guys i finally got some powder and my dies i would like to know what primers you guys are using with h110. small rifle? i would assume so but maybe small rifle magnum primers. i have seen a lot of powder data but pimer choice was hard to come by in this thread.

[MudBug]

In Hornady's Data they use Winchester Small Rifle. That's what I've been using.

BD

I chucked the end of the collet that sticks out of the housing up in my lathe so that the housing was smack up against the jaws of the chuck, then I screwed the nut that is on the housing tight against the chuck jaws. Further tightening will force the housing away from the chuck and off of the collet.

If you don't have a lathe you could use a vise with a couple of chunks of wood to protect the collet end. Or vise grips, a C clamp, somebody with a really string grip, you get the picture.

I have used primarily WSR's. I had a good supply. I did have some CCI SRM's and tried those with Lil'Gun and a 300 gr. bullet. My velocities with the CCI's were 100 to 150 feet per second less that with the Winchesters. If hornady is using winchesters -- it is for a very good reason. Also note that on Hornady's web site they have loading data for the FTX bullet and say that Lil'Gun is the powder of choice. Go ahead and burn up the H110, but I really like Lil'Gun.

I just put the die in my reloading press and punched the collet out with a proper fitted wood dowel. It is just a snap ring that holds it in.

Much easier!

When it comes to good info on this thread, Siringo is the "go to" guy!
