I have very little experience in reduced loads, but would like to create some for my 600 Overkill. I am thinking 1040gr cast bullet around 1200fps. Or a Barnes flatpoint solid about the same velocity. Any suggestions?

Check with Bitterroot (Wayne at AHR). he doesn't do well with big-recoiling guns so loads them way down to .22 short levels and even then uses a lead-sled.

Seriously, Wayne or Robgunbuilder would probably be your best bet for plinking loads. I think the slowest I have pushed mine was about 1600fps. I could look at my records and let you know what I used to get there but it will be a few weeks - still unpacking boxes after a move.

Wayne is making a batch of 2150fps as we write. I was thinking about the amount of penetration I get with a 325gr hard cast in my 454 @ about 1200fps and figured 900-1040 around 1100-1300 would be phenominal and a great plinker to boot. I have extensive data from PWS but nothing quite that slow.

Try working up loads using Trailboss powder. Just start at 70% volume and work up from there. My dad who is now on blood thinners has has excellent results with it in his .45-70s and .45-90s.

Ive never done any reduced loads in this caliber as the std 165gr of IMR7828 and 900 gr woodleighs are so easy to shoot! With that said, I would probably go with 45-50 gr of 5744 and a lead bullet of 900 grs. Alternatively you could try some 300 gr aluminum bullets with 125-130 gr of IMR 7828. That should probably hit 3000 fps with no recoil to talk about.-Rob

Wooooo!!!!

That would be very nice ...

I think there's not only confusion here about "Solids" versus "Mono-Metal" expanding bullets, but also about the term "opening up". The person may have been trying to explain that at the lower velocities (long range), the Barnes-type bullets may not "open up" (expand), as in wound channel.

Biebs,

I don't too much care about expansion or long range with the Overkill. I figure I'll not shoot anything over 200yds with this piece.


Rob,

Thank you for the data for "light loads". My brother is not a hunter or a shooter, but my neice is and I would like to have some loads she could shoot and gradually work up to "real" loads. It would also be nice to have some stupid light loads for fun shoots so as not to get beat up during competitions. I was worried about having to use some kind of filler such as Dacron to keep the powder on the primer and not laydown in the case and possibly cause detonation or whatever they call it with light loads in high volume cases. 3000fps with aluminum!!!!HS Will the silica content of the aluminum be a concern as to abrasiveness in the bore?

Andy

I have had great results with 45gr of Trailboss and 900 gr cast and 900 gr woodleigh softs. I have not cronographed it yet but the guy who gave me the load claimed 1200 fps. It does not recoil at all and almost makes you think you wasted a bullet.

Matthew

I believe the aluminum oxide skin is stripped from the bulllet in the first inch of rifling, so if anything you are performing a David Tubb finial finish on your bore with Aluminum bullets. I bore scope my bores occasionally and so far they look good. The Aluminum bullets hit very hard out to 100 yrds and 50 yrd off-hand accuracy is as good as anything else. Be the first to wear out the bore of a .600OK! -Rob

I have cut brass round stock into 3.3ft lengths and am still waiting for a PM response to my PM for a shipping address from the person that said they would turn it into bullets for me. I can also supply 3.3ft sections of 5/8 Al round stock. Need to know what series of Al to get...2024, 5250, 6061, 6063, 7075 and what heat condition? I assume it needs to be T6 or T65 but not sure. I know that "O" condition is out of the question.

Andy

MatthewX, Viper,

Thanks for the info. I was waiting to see if more than one person recommended Trailboss. Do these loads make less noise too? When you shoot them does it make you want to check the bore for obstructions after firing? Does it feel and/or sound like a squibb load?

Andy

Less noise but still sounds like a rifleshot, not a squib. Many times you can hear the projectile hit the backstop down range.

If you are shooting regular loads in a big bore and switch mid shoot then the first round or two feel like a squib due to the lack of kick. After a few shots you get use to them and have a great time without the recoil.

REALLY light 600 OK loads?

A REALLY light 900 gr load?

900gr around 1200fps is really light compared to the 2400fps that some shoot! Hell, thats half the normal velocity!!

Like Viper said it does not feel like a squib, but when you switch midstream you certainly feel a huge difference.

I also have a guy who will turn bullets and has made me several including a bunch of aluminums I have yet to work with. Let me know if you need contact info.

Matthew

FWIW- Most guys shoot their .600OK's in the 2150-2300 fps range. You generally only shoot them once or twice above 2400fps. -Rob

Even you Rob? Are you telling me you don't regularly touch off 900gr at 2800??!!

I'm disappointed.

What about pushing 750gr around 2800? Is this doable without too much trouble?

'Squatch

I went 2450fps with a 900gr woodleigh, over a chronograph to prove I could take it. Gun nearly torqued out of my hand and recoil was VERY STOUT, bordering on dangerous!. I prefer the 2150fps loads myself as they are pleasant to shoot and you can relax enough to still shoot acurately. When you shoot loads over 2300fps you need to REALLY pay attention to shooting form and make no mistakes. Other than the potential to physically lose control of the rifle and break bones, not sure what more anyone needs than what that load can deliver. The reason I dont like to give out the real heavy loads, is the potential for folks even very experienced ones to really get hurt. Yes the 750's are very easy to shoot and in many ways if your looking for less recoil, a better option than light loads with 900gr bullets..

Dont suppose you got that on video?

I certainly agree with that

AND, they penetrate through most anything in their way. I think those I shot last Spring might STILL be flying!
