E-Tips, what's up with the reduced charges
 Login/Join

I have a great load that I have used in my .270 with 130 gr BT's. I got some E-Tips to try for an upcoming cow elk hunt. I thought this would be the standard start lower than the current load and work up just to make sure everything is safe. Well I open the box of E-Tips and there is a little note inside "from the lab" stating to start with the minimum load and not to exceed the mid load listed in their manual.

My current load with the 130 BT's is 59.0 grs of H-4831SC that averages 3090 fps. The minimum load in their manual is 54.0 grs and the mid load is 57.0 grs. Why is this? Why would anyone use this bullet if it is going to handicap you velocity wise from the start? Any body used these E-Tips that had a proven BT load? I think I will box these up and return them and go with the Barnes TSX.

gilding metal isn't as maleable as a BT with a lead core meaning it generates more resistance via reduced ability to compress inside the bore which raises chamber pressures. Same problem with Barnes x-bullets although their triple shocks have somewhat alleviated the problem by reducing the surface area contacting the bore which also reduces friction.

They may give you the same velocity with the lessor powder charge.

Check the length of the E-Tip bullets and you will find that they are longer than same weight lead based bullets. The longer length extends farther into the case reducing case volume and creating higher pressure for same size charge. Lead is more dense than the gilding alloy. The Barnes MRX bullets use tungsten core which is more dense than lead to shorten the length of their speciality bullet and improve it BC. Just my humble opinion. I would venture to say the Barnes TSX bullet will be similar length as the Nosler E-Tip, because of similar bullet material is used in making the bullet. I have not measured a Barnes TSX/TTSX bullet of same caliber and grain bullets against a Nosler E-Tip so I am not sure of this.

I bet in the future Nosler will opt for the grooved design that Barns and now Hornady use.

In the bullet makeing forum most everyone that is CNC turning thier own has went to grooves to drop preasure and to keep more cooper out of the barrel for more shots in between cleaning.

Remington, has now dove into the California bullet market.

NC powder becomes more virulent the tighter the tamping is.

A harder bullet will do exactly this.

American bullet manufacturers make it easy on themselves by issuing load data which is supposed to be valid for all their bullets of one weight. This is misleading, dangerous and the biggest BS I have seen in reloading so far.

What is NC powder? Non-Corosive?

As far as bullet manufaturers giveing load data for all of their bullets as generic....not in my Sierra,Nosler,Hornady manuals.

NC: Nitrocellulose. This is what you are loading. Man, what are you doing on this forum?

And I didn't say, ALL bullet, but all bullet of one weight. I hope you read the loading tables a little more dilligently than posts on the internet.

Probably not your first.

Well gee...

I have been reloading for about 30 plus years and I didn't equate NC with nitro cellulose.

Legistine actu quod scripsi?

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.

McFox, are you always an A--hole???

It was a perfectly valid question as I was wondering the same thing when I read your diatribe. BTW-I load smokeless and black powder, not just NC (which really isn't an accurate descriptor of many of the double-base propellants marketed today and thus shouldn't be used.)

May I suggest you actually check around and learn a little before making such a generalized -- no to mention INCORRECT -- statement???

I have noticed that the knowledge base of poeple on this forum is very divers.

And I would like to offer my aplologies to Ted Thorn for being impolite to him. He was indeed asking a valid question about something, which I mistakenly assumed to be common knowledge amongst reloaders.

Regarding the loading manual, I keep my statement upright.
Nosler, Sierra, Barnes, Hornady ... they all do it. And don't tell me this is not so. I have them here, right in front of me.

C-Roy,

Back to the question at hand....

As has been said, the original Barnes X bullets showed high pressures at lower powder weights than many other bullets, probably due to the 'solid' design and the full shank of the bullet riding on the rifling.

The original Barnes X were also very, very sensitive to load changes, and were not known for stellar accuracy. I used them anyway because they hit game so hard.

The Barnes TSX is extremely accurate in the 8 rifles and 6 calibers I load them in.

I have no experience with the E-tip.

Hey Ted, NC is..., and always will be... - North Carolina! Big Grin Didn't know we had any special Powders in either of the Carolinas though.

Perhaps he mis-spelled "Smokeless". rotflmo

I should have known that. But around here NC = Tyler Hasborough. He is from the town I call home, Poplar Bluff. He is quite the celebrity here. But he is now an Indiana Pacer.
