| 308 Win. Powder crush? | Login/Join |

Morning everyone, I have a can of IMR4350 and I want to use it in my 308 Win. With 50 grains of 4350 the powder is full to the top of the case. I'm using a 150 gr Interbond BT. | ||

Use a 6" or longer drop tube and vibrate the case a little when you fill it. Some of my loads are pretty compressed.

As Frank said long drop tube slow pour and vibrate. Pick up any OAL you can. QL calls your load at 113.7%. I usually try to stay below 110%. No real science behind my limit. As usual just my $.02 Paul K | |||

You cannot compress powder to where it becomes dangerous! We have tried it, to where the case actually started to bulge. All worked just fine. As suggested, use a long drop tube. | |||

Yes, but do what Fj said; if it is completely full as dropped, I would not compress it that much. It can make the bullets pop out. You won't be able to tell the difference in 48 grains vs 50. It will be a slow load anyway. It is not a matter of safety. I see Saeed came in whilst I was typing; of course he is right. | |||

Cases for the .308 vary significantly in capacity. Try a different brand (Winchester typically has the most internal capacity) along with dropping your powder through a long tube. | |||

Another thing: make sure your primer pockets are tight; a compressed load will pop the primers, sometimes well after you load them. | |||

It must be the shaking that does it. I've used two-foot drop tubes and find they give negligible extra capacity. | |||

With respect to cases, I have hornady's to have the greatest capacity. PM if you want to try some. Mike Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.  What I have learned on AR, since 2001: 1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken. 2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps. 3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges. 4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down. 5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine. 6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle. 7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions. 8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA. 9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not. 10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact. 11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores. 12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence. 13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances. | |||

Thanks to all who replied. I'm gonna keep packing it in. the manuals all say it's not pushing the pressure too much. I'll see how they shoot!! | |||

Another trick if you are singly loading them is to "swirl" the powder down the funnel. It works for me. The shaking is also a very real thing as well. Larry "Peace is that brief glorious moment in history, when everybody stands around reloading" -- Thomas Jefferson | |||

I use an old hand held sander. Just hold the case against the rubber pad and it will settle the powder very quickly. Make sure you keep your finger over the mouth of the case or the powder will jump out. Tom Z NRA Life Member | |||

just asking.. but why 4350 ? why not use a powder more suitable for the 308 win. why not 4895, RL-15, varget, 4064, or IMR4166 I use mostly RL-15, I try not to load ammo mush over 95% density.. | |||
|
| one of us |
I was actually going say shoot Varget or RL15. | |||

 Not considering the crushing, Isn't 50grains of IMR 4350 a bit much??? How did you arrive at that weight?  rogerOld age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone.. | |||

I much prefer Varget in the .308. but my all time favorite powder for my 308s has always been WW-748, less pressure and more velocity and always accurate..With Varget and a number of Powders in the .308 powder crush only becomes a problem when it slightly pushes your bullet our over night, with a maximum load, then you need to cut back a grain..Like old WW2 4831 in the 30-06 velocity was high as hell and it would take all you could pack in and still be under 50,000 PSI, but 63 grs would push bullets our with recoil and just sitting in the box overnight..so Jack O'Connor used 62 grs all his life, same with the 270..Great powder and I still have 40 pounds. This only applies to certain powders btw, don't try it with others. Ray Atkinson Atkinson Hunting Adventures 10 Ward Lane, Filer, Idaho, 83328 208-731-4120 rayatkinsonhunting@gmail.com | |||
