Long time reloader here.  But new to the 6.5 Creedmore.  

I've noted that Lapua, which has the best apparent reputation for amazingly  accurate and precise cases, uses a small rifle primer in the creed more (while every body else uses LR primers).  Apparently, the bench rest, OCD crowd believes the small primers and lapua's smaller-than-standard flash hole diameter to be of benefit for accuracy.

Lapua is basically sold out everywhere.  But I've noted that starline is making 6.5 creed cases.  And they make them with large rifle primers.  And a second variant with small rifle primers (but a standard diameter flash hole).

Anyone actually observe or experience an accuracy difference/improvement with the small rifle primers?  While starling handgun cases are great, how does their rifle cases match up, consistency wise?

Thanks

According to many benchrest shooters the 6.5x47 Lapua is slightly more accurate over the 6.5 Creedmoor and many attribute it to the lapua using small rifle primers.

I dont buy that.  The purpose behind using small primers and small flash holes is to allow you to use a higher powder charge without seeing pressure signs at the primer, as small primers are simply more pressure resistant.  The 6.5CM and 6.5x47 are both great rounds.  The CM is hampered slightly by its use of large primers because it hits its pressure max before the x47.  However, now that small primer cases are available the CM should be able to sneak up on the x47.  The other real advantage the x47 has it that the case is more conducive running the bullets out there alot longer due to the way the case is designed, allowing you set your bullets exactly where you want them and allowing you to chase the lands as the barrel wears.

A shipment of Lapua 6.5 creedmoor hit the shores recently so should be seeing it on
dealer shelves soon.  
Starline has both large and small primer pocket brass.  The small comes with standard flash hole. 0.080".

One has to let your gun / barrel do the talking.  


There was widely circulated article written a few years back.  Basically it came down to chose your poison... 260-6.5x47-6.5 Creed.  At the time Hornady was handicapped the creedmoor with lack of brass.
Some resorted to using 22-250 brass to neck up etc.

Now there are all kinds of choices out there

Hornady
Nosler
Lapua
Peterson
Kinetic
Alpha
Starline
