Winchester 125 gr Open Tipped target bullets

[StoneHendge]

Any one have any experience with these? RMR has pulls for cheap (+/- 20 cents per) which could make for good high volume practice fodder.

Just ordered 500 a few days ago. Hope they shoot.

Received my order for 500 125gr open tip bullets from RMR. Cursory examination showed one bullet with a corroded tip but otherwise no glaring abnormalities. As a bonus they sent an additional 45 bullets in a separate bag as free. A nice touch. I have purchased a lot of bullets from them over the years and have always been satisfied.
Time to load some up and shoot them. And of course the corroded one will be sent down range.

These are pull-downs from Winchester’s 6.5 Creedmoor Deer Season Extreme Point XP.

It’s basically like a Nosler Ballistic Tip but with a much larger tip with more frontal area to expand rapidly underneath.

Most people that have hunted with them across different calibers say they don’t exit, but they really put the animals down fast due to rapid expansion.

Some people had problems with them in auto-loaders where the tips broke off. This was my first suspicion as to why there might be so many pull-downs available.



For performance on-game, they should be ideal for 6.5 Grendel’s moderate speeds as far as expansion goes.

One thing consistent about reviews with this bullet is how unbelievably-accurate it is.

The biggest potential hiccup will be whether the tips break off when being fed through an AR-15.

BC G1 is listed at .540, which is likely inflated since there is only a token boat tail, though the meplat is very secant.



If they run fine without breaking tips, it would make a nice multi-use target, hunting, and HD bullet since it seems to stick in the animal’s thorax after penetrating and fully expanding.

Highbrow, if you have a chance to measure the OAL and base to ogive, it would be awesome. At first glance it looks like the nose is really long, but it looks like there's a lot of shank on the tip side of the cannelure and the cannelure would probably end up in a Grendel case neck to get it mag length in Grendel (it looks like it probably makes really good use of 6.5 CM case capacity).

52, they have that hunting bullet at RMR, but the target bullet I'm talking about is from Whitebox Creedmoor target ammo: https://www.winchester.com/Products/Ammu...1%22%5D%7D

My coal is 2.230. Didn’t measure distance to lands. Bullet length is 1.143 inches. Base to ogive is .563 inches. Had to seat above the cannelure. [ATTACH=CONFIG]19963[/ATTACH][ATTACH=CONFIG]19964[/ATTACH]

Sorry, I clicked on the link and then got rubber-necked over to the 125gr tipped bullets.

Looks like the 125gr OTMs are pull-downs from Winchester OTM target practice ammo.

Thanks! The nose is a tad long, but it looks like Duramag max length (2.310) would put them right around the lands in my tight chamber (I do 123 Scenars with a 0.03 jump at 2.250 OAL) and the base won't go much deeper than the shoulder/body junction.

FWIW, using the 400 yard drop on the back of their ammo box, their velocity of 2850 and sea level density altitude, I back into a G1 of around 0.295

SH:

Base goes to the shoulder at a really good OAL. Good sign.

I made a bunch of flat base bullets of that design (without the cannelure) many years ago when swaging jacketed bullets. Both 6.5 and .308. Given not much wind, they were super accurate to five hundred but I shot them mostly at 200 and 300.

You may have something that will surprise you providing they weren't damaged when being pulled.

I wonder why they were pulled?

Had a few that looked like this. Maybe 6.

It could be if they had some 6.5 Creedmoor factory ammo exposed to water damage, they had to just pull the lot instead of shipping ammo to vendors that looks like that when the customers open the boxes.

Finally got a chance to send some of these down range.
Shot out of my cheap Radical Firearms AR. Random fire formed
7.62x39 LRP brass and 24.5 gr IMR 3031. Function was perfect.
