Thread: Sierras new Game changer bullets

I've managed to get them to shoot ok 1'' or less in a standard .243 barrel (1-10" Tikka). Did have to change powder from the ever reliable 2209 in the .243 to N160 but its done the job.

That's good to hear @Dreamer. Have you had the chance to test accuracy at longer range? Like 300m? 400m? Its possible that a marginally stable bullet (which this is) could start to miss behave quite badly as it slows down, pitching and yawing and increasingly drag. There is a video out there somewhere of the results of this with one of the Bergers shot from a barrel with a marginal twist rate. Good 100m accuracy but really shit down range. It might not matter if you are not planning on shooting stuff at close range though.

@Flyblown shot this group at 400yds this morning bare in mind I haven’t got the rifle sighted in for these and should have used my bigger plate but the first shot hit top left corner then the 2 to the right at the top so they seem to stabilise fine for me.

That's excellent. So it does appear true, what the Sierra technician said, some 1:10" barrels will, some won't.

This is one of the best results I've seen on the web for the 90gr 6mm bullet.

Bloody good advert for Tikkas as well.

It's actually a secondhand gunworks fluted tikka barrel screwed on to a Sako A2 in a Ken Henderson stock so a bit of a cross breed Soon to be rebarreled with a 1-8" bartlien chambered in 6mm creedmoor though.

Have just worked up a load with the 130gn G/C in my 260 carbonlite, 20” barrel and got 2860fps with Superformance. One trip to the range for a ladder test, then another for some groups..done, very easy. Be interestingly to see how they go on deer.

Guys, Check out the new Sierra App. Pretty cool

Bit of an update to this thread guys.
After a year of using the Game Changes myself, and developing a tonne of custom loads with them. 6.5-30 cals. They have proven to be an exceptional bullet.
I haven't developed a load that shoots more than 1/2 MOA and have had several go 1/4.
Performance on Game is exactly what you expect from an expanding bullet. I keep telling guys, in summary, the perform like an accubond, but are generally more accurate, and have a better BC.
I have not loaded 6mm, but have heard tighter twists are required.

I'm looking forward to the day Sierra release heavy options in 30 and 6.5 cals!

Please feel free to email me at info@blackwatchreloading if I can offer any advive from personal experience. Cheers

My only experience is with the 6.5 130gr GC from a Schultz and Larsen 6.5-284. The load I developed produced groups of .24 MOA at 100m that still hold .44 MOA at 400m. So far the only Red Stag I have shot with them was at 300m and I hit him in the neck about 100mm below the head. The exit hole measured about 23mm.

@300AAC On your Instagram those are some pretty massive exit wound holes on those smaller deer, eh.

A couple are @Flyblown. Different to a Berger explosion. Like i say, more like a accubond. They drop them big time

I'm sure they do drop them with exit wounds like that. As a meat hunter I want a bullet to do all the damage internally and preferably not somewhere in the neighbouring district. The GameChanger looks like a very good large game (150kg+++) bullet but gut feel is in 6mm and 6.5mm a softer fragmenting bullet is a better option for fast killing. What has changed in deer design that needs a harder bullet than ProHunter or GameKing?!

Plenty of other options out there for you then @Flyblown... Sounds like you are more than happy with your current selection of pro hunters and gamekings, which, by the way, are legendary bullets! Why not stick with what works for you? Of course what works for you isn't always someone else's cup of tea.
I think you'll find the reason for the discussion on this forum, and this thread in particular, is for those guy's looking for real world experience's of something a bit different.

Cheers

A bit different to what Jared?

Look I see what you're saying, but I just don't buy the underlying design premise that a high BC, hard, controlled expansion style bullet is a great idea, that changes any games. The high bc only helps >400-500m or whatever the relevant range is for the calibre and weight you're looking at. This bullet on our deer at extended ranges - if shot placement isn't spot on - is just going to sail straight through and a lot of the energy is lost. We can agree that proper long range shooting with hard bullets isn't a good idea?

I put my hand up - no, I haven't used them. Happy to be shot down for that reason alone. I can see you're very pro Sierra with a lot of interaction from them on your Instagram, promoting the brand. I love Sierra bullets and have used them for over 30 years, and I think I do know the reason for this thread in particular... to discuss pros and cons of new designs and risks and hopefully sharing a bit of real world experiences with all sorts of bullet designs in specific applications. Some of us will agree that the new kid on the block must be great across the board, others will be quite skeptical, like you were about the ELD-X!
