It seems bullet manufacturers are riding the market wave for higher and higher ballistic coefficients in their products. With a set diameter, only bullet shape and bullet weight play major roles in the external ballistics of the projectile. I’m using the term shape to describe predominantly the ogive and bullet base forms incorporated in modern projectiles. Bullet shape seems to have been optimized and now there is a push to increase bullet weight to increase length and thus BC of the bullet. Case in point - the 147 gr Hornady and 150 gr Sierra offerings for the 6.5 bore.
Precision shooting correctly focuses on bullet BC, but time to target (velocity) is also an important factor. The 150 gr Sierra comes with a recommendation to use a faster barrel twist which inhibits velocity. With increasing bullet weight, increased barrel twist, and a static case capacity, it seems there has to be a point where limitations in velocity begin to defeat any benefit of increased BC. If this logic is correct, where is that point for the 6.5 Creedmoor case?
Another way of asking this question would be: Are the newer (145 + gr) 6.5 mm projectiles better suited for cases with capacities larger than the Creedmoor, such as the new PRS or the older 6.5/284 cases?
Bryce Towsley wrote a good, generally informative, article for SI on the 6.5 Creedmoor. His notes on powder options are right on point. Check it out if you can. I would like to see this gentleman in our membership. 😊
Here is a question for the action gurus of our family. I have a model 12 action in my LRP. Great rifle with very good accuracy thru a 28" Bartlein barrel. I shoot it prone on steel. Sometimes I get super aggravated when cycling a round because the bolt lift is so stiff that I lose my target picture in the scope. Even when stabilizing the stock with the bag and my left hand the rifle rotates more than I like. I have large strong hands, but the bolt lift is still too hard to allow me to lever it up with my thumb anchored to the back of the receiver. May be I'm spoiled from running my Kelbley and RPR actions which do not do this. I believe the Savage action cocks the firing pin on elevation of the bolt handle. Is there some bolt kit that I can install to make the action easier to cycle?
Great experience with these folks today. I had H4350 on my wish list and decided to call this morning to see when they were expecting a new shipment. While I was on the phone with Trent the Hodgdon delivery truck pulled into their unloading dock at 10:30. They unloaded the shipment processed my order and had it on the FedEx truck at 2:30. Four hours total to turn the product out for me. That's just plain good service. Thanx guys!
It seems like in the competition world, the most favorite 6mm cartridge is constantly changing. Lapua brass has almost always been an advantage to the 6mm BR shooter. The latest and greatest 6 Dasher die hards are now intensely interested in the new 6BRA which is simply an Ackley Improved 6 BR (Lapua brass). Lapua got smart and started producing a SP Creedmoor case recently to equal the playing field between the 6.5 Creedmoor and the 6.5x47. Those guys shooting 6.5 Creedmoor brass necked down to 6 Creedmoor no longer have to convert Lapua 308 Palma cases to Creedmoor 6.5 mm or 6 mm brass to get a small primer case.
If you look at these changes and forget about the traditional 6 mm cartridges and also realize the 6 BRA hasn't been around long enough to really be proven, it might make you stop and pause for a question. Its possible the new SP Creedmoor Lapua brass also hasn't been available long enough to judge but, here is the question.
Question for the initiated: In competition, how are the 6mm Creedmoors, using small primer Lapua brass, doing against the 6mm Dasher?
I am so sick and tired of the puny 4 round factory magazine in my Savage LRP. Ive done a little research over on the Savage Shooters forum looking for an after market 10 round replacement. Looks like maybe the best choice out there is the one made by Dark Eagle Custom. Does anyone have experience with this product or do you have another suggestion?
Service men and women, past and present, here and abroad, today we stop to say thank you. For me that recognition is not a brief thought in passing but rather a deep appreciation of you and the many sacrifices your family's make to provide the security for my freedom and the pride I feel in my nation's strength and place in the world. You are,bar none, the best there has ever been. From my family to you and your's, Thank You Very Much.
I've been dragging my feet getting around to working with the new small primer Lapua brass. As I get closer, thinking about load development, it's occurred to me that I could start with different brass and a different bullet. The new 121 gr monolith Flatline bullets from Warner Tool (designed by Josh Kunz) really have me drooling with phenomenal velocity and an off the wall BC. Snipers Hide has a video of these Bullets running 3200 fps and drilling steel at one mile. They are expensive (about $1.20 a piece) so - not to plink with.
I have done very little work with the 120 gr bullets that have been available and no work with the small primer brass. So...... what would you all consider looking at as a powder choice for this combo?
