Just completing a build that will be chambered in a 30-284 and I'm planning on using 130 grain bullets. i should be able to get around 3500fps out of it. i might have to go with the 150's if the 130 Barnes bullets do not work.

Couple questions:

has anyone used this round with the lighter bullets and if so, what was your combo to make it work?

Anyone aware of some other 30cal 130grain bullets on the market other than Barnes?

thanks

i plan on using it for a windy day coyote contest gun and deer/antelope.

Build info - Stiller tac300, Brux 14 twist, manners stock, jewell trigger, NF 5.5-22 to top it off.
 
I'm curious on why you settled on the .30 vs 6.5mm for this setup? Sounds like a sweet rig! I hope you let us know how it shoots.
 
As with many 600 yard comp shooters... i tried the 6.5 war and lost. There are a few guys that got the 6.5's to work and won with them in 600 & 1000 comp,,, but I and several that i shoot with have not. So, i have ruled 6.5's out for that reason and not saying that they don't work just saying that I fought that battle and won't use one again. I'll stick with the 6's and 30's.

Copper,

I have been looking at the 284 family of cartridges lately also. It appears to me that a 284 case has about the same powder capacity as the 30-06 but will fit in a short action. So, if the 30-06 won't shoot 130 bullet 3500 fps how are you going to get that velocity out of a 30-284? How long is the barrel on your build?

According to Hodgdon's website even the Weatherby 300 mag does not push the Barnes 130 that fast.

Good luck on the new build. Be sure and post some pics when you are done. I am jealous.
 
CalCoyote, You read my mind on the fps dilemma.

But, This reamer was a brainchild of gunsmith jerry Simison and it was designed to push 190's for 600-1000yd stuff. Anyway, it is not a straight 30-284 but i don't know the exact dimensions.

My buddy was running one for the long range BR game and was getting close to 300wm speeds with 190's.

So, my buddy says i will get somewhere between the 30-06 and 300WM. We ran the straight 30-284 through a program and it says around 3500 with 130's but high on the pressure chart so i'm thinking maybe with the exra capacity it will work.

I'll post when done,,, brux 14 twist should be here shortly.

There are two .30-284 cartridges listed in QuickLoad. One is labeled .30-284 @ 66 water grains and 59,465 psi rating, the other is a .30-284Win @ 67 water grains and 55,114 psi. I don't know which one, if either, matches your brass. FWIW: Neither will push a 130g bullet to 3,500 fps within it's max pressure limits out of a 26" barrel. The Winchester needs 67,000 psi to get there in models which is ~22% past max, the other needs 68,102 psi which is 14.5% above it's max pressure rating.

The better of the two needs a barrel 34" long to get there at exactly the max rated pressure.

OTOH, with the intent to bring a solution rather than just issues:

A .30-338 Lapua would get you there (130g @ 3,500 fps) nicely within rated pressures. If you haven't chambered it yet you might consider that as an option. My model load for the .30-338 Lapua (same bullet as above, 26" barrel, 90.3g of IMR7828SSC) easily gets 3,513 out of a 26" barrel @ 56,000 psi in 64,000 psi rated brass. No muss, no fuss, no magic, just solid performance. Excellent brass and bullets easy to find for that cartridge.

There is no magic in cartridges, only physics. Physics is what it is. It isn't negotiable. Nobody can fool mother nature. It doesn't behave differently for big name reamer designers than it does for anybody else. You pay your money, you take your chances.

My all time favorite quote on technology comes to mind looking at this data - it is the last sentence from the Appendix to the Rogers Commission Report on the Space Shuttle Challenger Accident" titled "Personal observations on the reliability of the Shuttle", by R. P. Feynman:

For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.

Feynman got it right.

YMMV.

Thanks Fitch... I have a .338 Lapua alrady and don't want to go that big since I have a standard bf on the Stiller. Maybe I should have went with the slower twist and just ran 110vax's or 125bt's and gave a little on the BC.

I like staying in that 3500fps area (+or- 50fps).

My other option is to go with a 22-6mm which will push 80's at 3500 and with the excellent BC with amx,berg, sierra it would really cut the wind but don't know on the performance on actual coyotes. I know of 2 guys building them right now so we will see what their field report says.
