.277 shooters

[TT_270wsm]

If anyone has any random .277 bullets to sell in smaller quantity (10 or so) please see my ad in the EE here: http://www.canadiangunnutz.com/forum/showthread.php?886928-Assorted-277-bullets-for-test!

I'm going to be doing a wet-pack bullet test this summer out of my X-Bolt 270 WSM, comparing bullets at standard hunting velocity as well as comparing different velocities vs. expansion/penetration.

Also, if anyone is willing to donate any bullets not on my current list, I will gladly pay for shipping and give credit in my write-up. Test will be performed very similarly to BCSteve's .264 bullet test here: http://www.canadiangunnutz.com/foru...-CGN-264-Bullet-Test-Result**-(lots-of-pics!)

Particular bullets I am looking for and do not have any currently are anything bonded, as well as Nosler Partitions.

Thanks in advance,

TT

I have this to offer.

 

[TT_270wsm]

Anything that you're willing to contribute or sell in quantities of 10 is greatly appreciated. Last night I loaded bullets in all the weights with all kinds of crazy reduced loads to try and simulate the velocities at different yardages, gonna hit the range with my chron this weekend hopefully! PM me for more info.

 

[Canadian_Zuk]

Pm your address, I ship some to you.

Bullet performance testing:

A bullet wiggle waggles for at least the first 50 yards and often as far as 100 yards. This yaw will affect how the bullet penetrates and expands.

If you are going to reduce powder charges to simulate 200, 300, 400 yards (which I would find interesting) I suggest placing your target at 100 yards so the bullet is not yawing when it hits.. An ATV would help. You can Chrony at 15 yards and calculate the drop in velocity at 100.

A 50 yard test at full velocity would be good, too, since we often hit targets at that distance.

I will check to see what I have. Do you want some Barnes X bullets to try?

If you haven't found some 140 grain accubonds let me know and I'll ship you some.

Still waiting on the AB Long range bullets to arrive from Omineca, and would still be interested in adding any regular Accubonds or heavier partitions if anyone has them to sell. I think we have the standard cup and core bullet segment covered thoroughly! Lol. Thank you to all the members who have contributed bullets! So far I have 4x 18" deep stacks of newspaper ready to shoot, and collecting more every day. I may end up omitting some of the more redundant comparisons (such as Hornady IL vs pre-IL SP's) depending on time constraints and newspaper supply, we'll have to see how it goes. I've got all my reduced load data ready except for the 150's and 165 Matrix, after I get back from a turkey hunt next weekend I'll finish off my load data, and start shooting some newspaper.

Here is a breakdown of what will be recorded from every shot:

-Penetration
-Wound diameter @ 3" (will be shooting through 1L milk cartons filled with water, have duct-taped the boxes to try to see what kind of expansion each bullet achieves at the 3" mark)
-Retained weight
-Final bullet expansion

The last one is the parameter that I have the most trouble with when seeing other bullet tests, as I feel that the maximum diameter (even if it's a sliver of lead) isn't really representative of a bullet's lethality. I was considering using some string, and tracing the circumference of the expanded bullet's imprint to give a more accurate comparison, but it will present quite the challenge. Any input on this part is greatly appreciated! Worst case scenario, measuring the expanded diameter at 2-3 different points and averaging it out would work too.

glad to see those 110 gr TTSX made it.

 

[nanuk]

hard to measure a TTX as their petals are so evenly spaced that at 4 places around the bullet, you'd have 0.277 to add in.....

I dunno, take a picture, input it in to AutoCad, and measure area???

 

[nanuk]

glad to see those 110 gr TTSX made it.

I expect the 110TTSX will be above average, and impressive with velocity.

I think they are the best compromise for speed/penetration/retained weight.

I want to try some in my 26" Ruger.

 

[Dunk]

The 4th one looks like a TTSX not a TSX.

 

[Republic of Alberta]

The 130g Winchester SP looks like its actually a Remington core lock or the blue box Federal vital shock.

 

[TT_270wsm]

I'm going on the information that was given to me, it may very well be a Remington/Federal.

Dunk, you are right it is a TTSX, that much seems pretty obvious. Will change my description.

I was fortunate enough to get many more bonded Matrix bullets to throw in to the lineup, so other than the Accubond LR and possibly some 130-140 Gr accubonds if I can find some, we've got her locked up. I'm hoping to start getting some results up in the next week or so. It might take me all summer to get through all these damn bullets. More trips to the range I guess!

[Why not?]

How many 150 gr A-Frames do you need?

Ted

 

[TT_270wsm]

Ted, much appreciated but for the time being I'm going to stick to the ones I have. Once I get through all these, ill consider testing more!

[Cleftwynd]

Shoot me a PM with your address if you still want some 140 accubonds, the offer still stands.

 

[Cleftwynd]

Has anything come of this yet? Or did I miss the posts somewhere lol.

Last night I loaded bullets in all the weights with all kinds of crazy reduced loads to try and simulate the velocities at different yardages,

A test done with reduced loads is fundamentally flawed from the get-go. Cutting the velocity in half also reduces the rotational speed by half. Rotational speed changes very little even as a bullet slows in velocity, but plays a part in stability both in the air and in the test media.

The US army went through this with the 30-06 before we were born. They did the reduced velocity tests, then realizing the mistake had to redo everything with full velocity loads and some shooters that could actually hit the targets at extended ranges.

This plus wet newspaper really doesn't tell you much more than how it performs in wet newspaper. Ballistic gel is certainly a better option due to its elasticity, allowing both a view of the permanent and non-permanent wound channels. This elasticity allows a bullet to slow more naturally with a bit of "bounce back" and in many cases it may even tumble. Newspaper allows none of this. I don't think it will be hard to predict which bullets look the most impressive at the end...can everyone say mono metals.
