New 109 ELDM vs 108 ELDM

[wind gypsy]

I'm curious to hear how the 109s stabilize out of the 1:8 243 Tikka.

I took him saying "Hornady's software shows the stability factor at the muzzle in my current atmosphere to be 1.54, between that and my results on target I'm not sweating the twist" to mean they stabilize fine for him.

I’ve shot them out of 3 different 1-8 twist barrels at sea level. No issues.

Any with short barrel 243s at lower velocity? Useful datapoint for those considering the combo.

I plan to use them but I got a 1:7 barrel in route so shouldn't be any problem.

No sir. All shot at around 3200fps. Thank you for mentioning that.

Just got done working with some in a 20” tikka 243. I did not have good luck with them, the tightest they shot was 1.9moa but majority of the groups were 2.5-3moa. They were stabilizing at 100yds but the accuracy just wasn’t there. Maybe a different powder would have helped some but I wrote them off as I want to use the h4350 I have on hand.

@wind gypsy had the correct take.

The one and only group I've shot so far, 100 yds:

2850 FPS in a 1:8”. No problems for me

Just that alone can and will cause very different behavior.

People generally believe, and companies keep repeating- that “the tip drives back into the bullet causing expansion”. That is not what happens in almost all cases and it is clearly seen in gel.
Almost always the tip squishes out of the bullet soon after impact explaining the open cavity, or it breaks off creating a larger frontal diameter.
Aluminum/metal tips do neither- if the bullets upset it’s generally because the bullet started to yaw or starting to destabilized, then the tip get pressure on the side and it tears out of the jacket causing massive fragmentation. Other times it remains point first and exhibits basically no upset.

I killed two deer with the 135 A-Tip out of a 6.5 Creedmoor. Both wer heart shots at 456 and 275 yards, broke the off side leg, both deer went 100 and 250 yards with no bllod trail and the exit side of the heart was barely bigger than caliber size. Exits on the hide were nickle size at best. Most accurate bullet I have shot, but not for me for a hunting bullet. Maybe at a higher velocity and a shoulder shot, but not a heart/lung bullet.

Anyone load 109s in the 6arc? At the 5500-7500 feet I normally hunt, if I can get them going at 2700 out of a 20” Howa - that takes me around 750 yards to get down to 1800 FPS!

 

[RWT]

This thread has me concerned. I just picked up a used Howa 1500 in 6CM to build out for the nephew.

Based on the experiences there are more times multiple shots were required due to poor bullet performance. If this is the case what factory available loading is recommended?

I thought the ELDM’s were solid performers regardless of the weight or caliber?

Bringing this back to life, any more experiences on game?

I’m just starting a 6creed journey and have a few hundred 109’s to work up a load after I work through my supply of factory 108’s. Hoping to get 2900fps (aka 825 yards of expansion for my elevation) with a suppressed 20”. The factory rounds are shooting very well and make the 600 yard public range an easy going time.

 

[khuber84]

2900 from a 20" should be pretty doable! I run 2950 in ann18" so......

I got cold feet and didn’t hunt with them last year. But they shot the exact same groups as my 108 ELDM’s. So if your gun currently likes 108’s, it’s likely to like the 109’s as well! Please keep us updated!

Planning to run h4350, I have a pound or 20 of it….. what were you running? Brass?

Will do, spring bear will be here in no time!

41.1 grains of H4350, Peterson brass, CCI-BR2s nets me 2950 with the 108 and a 19" barrel. I worked up to 42.0 at 3,000 but it was a bit rough on brass.

I'd think 2900 with 109's in a 20" would be very attainable with H4350.

In my 20", 41.5gr H4350, jumping 50k, runs 2975. Lapua brass with cci450s.
