Rose vs Afterburner

Problem i see is the "mag fed" Mcguire bullets have a minimum expansion velocity of about 2200fps-- punched in a calculator and that would max out a std twist 300wsm at 500 yards and a 7 rm at 450 ish---- do they really not expand reliability under 2200fps?

Might be an issue for those looking for kills over 600 yards
So far I've never used the mag-fed design. Hasn't been a tip problem for me. You have a tight mag follower? Should be fine.
 
Gday
I'm going to have to get my 💩 together as got a few result's on these pills but cohunt I'm a Slovakian on the speed I can post lol

First comparison is

Apex are basically immune to the hydraulic system needed to get it to shed petals & on my last batch of 6.5 you can take marks word for the minimum velocity required to shed those petals & these pills were the best I tested @ the sub 1900 impacts hands down & not only these 2 companies that was with the like of the eldm as a comparison so yes the apex was king easily on what I've seen on these low impacts low resistance but one I honestly don't like but that's me

The copper rose has 3 pill types
The
hollow point
Magazine feed tip
Single feed tip

Hp first is one of the better hp design on the market as it's shape allows it to more or less funnel in material & that maybe not only be critter flesh as on dry mud it preformed pretty well on the no nose over & functioned well
But it also is one that a hydraulic system is needed to get it to work ( I'll get pictures to show this @ work ) & while better due to the funnel nose it's way better with wax added & I'll have to show where this is & to some it won't matter but impact to tip it's easily seen

Magazine feed not tested that yet

Single feed now that's a interesting one first off depends on your chambering as in my beanmore & the magazine of the sako 75 I had no issues whatsoever of stacking them in on top of ea other ( I done this before with hammers so was curious if it held up with mcquire & put 2 in bottom & shot for day with other brand pills on top & no damage I could see so I'm cool to just go shoot them others i think will run in to trouble so beware & test on self )
This cap tip I've still not full worked out the whole process but what it's doing is a interesting concept & im yet to fail it on it's applied targets so far which is a good start
It give a slight pop compared to the hp & a against the apex this is where it has the edge in that area but it's @ the mid 2000 it occurs @ so to some it won't offer the advantages of the apex as if your shooting a long way out & low impacts the apex is better ( this is 6.5 remember)
Which gets us to the bc both are pretty darn good & i didn't have to worry about to much juggling but bc ultimately is not a factor for me personally very often but others I see why so they are better off asking on comparing on the better people who care /want those things where I'm Moa of wallaby I'm good 😜( I'm basically a 500 & in guy but more 400 )

Now the other part of both pills is how long they hold the petals when shed in what I class as a coke can wound & the hp mcquire due to the hydraulic needed you get petals not travelling as far put beeswax in & that a whole different beast on the very few tests preformed so far so stay tuned

The SF that's unique as still requires hydraulic but it's showing a pop that's present but how I'm unsure so more testing need & that'll be in 30&338 cal with pills on way but I'm also happy with this pill as this deer showed some huge promise as this result reminds me of the 137hh 30 cal @ a considerable less impact speed

Will it hold up to the same level consistently
That time will tell but what a great start
Here's the comparison of the 30 cal 137 hh BDCEB59C-AFF1-4832-B7D2-F69FE03E97D4.png

& here's the 6.5 cal 125 SF copper rose @ if memory is correct around 700 /800 ish less fps impact

Now on these results & be interesting if it's repeated in the other calibers
The mcquire is showing better impact to tip with higher impacts over the apex
The apex is better in the lower to very low

The super high impacts I just can't push them high enough to determine what ea pill is doing in 6.5 but lookout once I get to the 30 cal lol
Cheers

The copper rose is a kinda of a hybrid of a shedding & mushroom mono
& please understand this is my interpretation as basically a lot of shedding pills cold be classified as a hybrid if we take it to the extreme of a slight mushroom

So what I have taken on board so far in the 6.5 it seems the mushroom mono part is present for about 300 /400 ish low impacts & then the shedding takes hold above this
& by mushroom we are talking a decent mushroom that's showing of wounds that it has a wide flat meplat on the mushroom part not a slight nose mushroom that a lot of pills have
But I've not caught any pills so I'm assuming on this & more testing needed to confirm so I'm not as concerned with these pills vrs say a Barnes or etip or a shedding that roles the nose I guess I'm saying etc that only mushrooms the tip @ the lower velocities
That's where I'm interpreting wounds as the size of the mcquire wounds @ mushroom part of pill are considerably better than the likes of others that only mushrooms the first part of the nose ( I need to get to recovered pills to really show & match with wounds if I can to hopefully show better on what I'm trying to relay )

Hope makes sense


Now also if you have a single stack mag Sam has a little invention that you may want to pester him as it allows a sf to be used with out drama I believe

This is something I want to compare with cross sections of each, but without doing that, and with what I know already, I'd say the "cap" on the mag fed is simply thicker to reduce the change of deformation, and because its thicker, it requires more impact velocity and more resistance to produce the proper expansion. Because this isn't simply a tip that can dislodge and move out of the way, its really dependent of sufficient impact velocity and resistance.

The single feed has a thinner "cap" and requires less impact velocity and resistance, but is much more sensitive and susceptible to deforming and you get that tradeoff in performance and capability.

I would agree the mag fed versions do not seem like good long range options due to the lower impact velocities commonly associated with long shots. I'm not trying to downplay the bullets or say they're a bad design, but I do think its a valid concern and worth mentioning and discussing, for sure.
 
I'd think it's safe to say that if you are shooting 500 yards and under then the mag fed would be a good bullet for you. If you are going longer then the single feed. I have found that if you practice enough with a single fed round that you can get pretty quick on the follow up shots at distance if need be.

I'd go with the single feed and run it in a magazine. At least try it once. Works for me with a tight follower. No issues terminally at close range so far for me.
