New to BR

Lots and lots of good advice here. Thanks to one and all. I am not a complete stranger to reloading as I have been loading for my .308 for several years now. I really enjoy it but I needed a new challenge. I tried to get into some competitive shooting with the my Savage but it was too heavy for silouette and not quite up to snuff for benchrest. Is there a factory rifle out there that is competitive in benchrest?

Reloading right there at the range is going to be a new experience. They have lots of practice days for benchrest so I will be frequently attending those observing and picking brains while Lester builds my rifle. I think what really sold me on benchrest was that one of the guys at the range said that the sport required "constant tinkering". THAT'S FOR ME!! :D

I will also be back in here making a pest of myself for the next several months I suspect.

Thanks
Harry

The 6mm PPC was designed in 1975 by Ferris Pindell and Louis Palmisano for bench rest shooting. PPC stands for Pindell-Palmisano Cartridge.
 
You need to know hat the Wedge bullet is almost .001 fatter than most bullets. This will be important as I assume you will need to turn your necks.

The brass I use for the Wedge bullets needed to be turned about .0003 thinner each side, or about .0006 total.

6 br

This means if you use a bullet with no pressure ring you'll like need new brass.
Told you should have gone with a no turn 6BR.
 
Factory rifles in Benchrest ?

I dont think so ... Nothing can compeat in Benchrest except custom built benchrest rifle specially built for that purpose by competent gunsmith from the best components awailable.

When was the last time a 6br won a short range registered BR match????

Bad advice.

Shot Out

When and where do you want to shoot one against another at 300 yards for groups?
I'm in MD.

Are you saying that a ppc is only good for short range work. I've seen the BR shoot 4" groups at 800 yards in the hands of an experienced BR shooter, which I am not.
 
6ppc/6br

The general consensus is that 6PPC is more accurate than a 6BR. Not much but enough to dominate the short range benchrest. In my opinion you can never trade ANY accuracy for a small gain in ballistic as some 100-200 fps would give you in 6BR over 6PPC. If thinking about I:8 twist and 105 gr 6mm bullet in a 6BR that setup will never give better aggregate at 100-200-300 yards than a conventional 1:14 68gr bullet from a 6PPC.

There is a vast difference between aggregate and a single group. The other day I took my daughter to the shooting range. Shooting her very first group from my 6PPC it measured .207 at 100 meters. I didnt vant to complicate things for her the first time and didnt instruct her in the use of windflags, thought just geting the hang of aiming and pulling the trigger would be tough enough for the first 20 shots or so. At the same time I was drilling out X at that distance so the condition was quite good. I was almost relieved when her next group was more in the nature of what I expected or I would just have had to find myself a new sport.

I have a .25-08 IMP that I have shot a 5 shot group under .200 at 100 meters from a bipod. Impossible you would say and I have to agree with you since that will never happen two times in a row let alone an aggregate. But I would shoot aggregate under .500 from a rest anyday. Dont know how much under .500 and it doesnt matter as it is a hunting rifle. Had my doughter try the 25-08 and that was a totally different story from her shooting the PPC. It takes experience shooting from a bipod and a beginner is afraid of the recoil of that rifle.

My conclusion is that 6PPC is the right thing to start with and shooting a good group is not the same thing as shooting an entire aggregate or 5 CONSECUTIVE groups.

Twud,
First off, I want to appoligize if I came across a little harsh with the "Bad Advice" comment. I didn't mean it that way but after most of my life being spent in the Army, I get kinda short and to the point with my answers sometimes.

The PPC, as used for short range Benchrest, is not a very good long range cartriage. Yes, some 500-600yds shoots have been won using it with a 65-68 grain bullet and a 14twist but it's not really suited for it. At ranges above 300yds...the 6BR is far superior to the PPC and maybe even at 300yds. The poster is in AZ and is going to be playing the Short Range BR game. If he wants to do both...order a action setup to pull and eject both the PPC and BR and get two barrels. You just can't leave anything on the table in any shooting competition anymore.

YIKES!!! Lots of great responses which lead to more questions. What is shooting agregate mean?

Bruno was pretty sure that the 6ppc was the correct caliber to go with and didn't mention any possibility of extra barrels or different chamberings. The rifle is in work so I am assuming it's too late to make such changes. Besides, the short range route is good enough for now. What do you mean by "you can't leave anything on the table anymore"???

harry,
an agg is the average of groups. Whether it be a single yardage, a single gun (LV, HV, etc) or any combination there of. Most of the time they fall like this for a LV, HV 2-gun Agg

LV100yd agg - 5-5 shot group average
LV200yd agg - 5-5 shot group average
LV Grand Agg - Average of 100 and 200 yds with the 200 yard portion being divided by two.
HV100yd agg - 5-5 shot average
HV200yd agg - 5-5 shot average
HV Grand agg - figure same as LV
2-Gun agg - Average of LV & HV averaged together

Hope that is not to confusing. Also, with a custom action, you can have as many barrels as you want made without the gunsmith having the action in hand because they are held to such close tolerances. You just change the barrels out yourself. When you get to shooting with Lester, Gary and them guys out west...they can show you how to do it....no harder than taking off and putting on a nut on a bolt...just remember to lube it.

Hovis
 
Well, I won't be changing out barrels anytime soon. I got the rifle today and it's a beauty alright. I am still a tad confused about the different reloading techniques. Bruno sold me a custom bushing to go with the custom die he made me. Not sure why I need it though. Do benchrest shooters normally FL size or neck size the cases?

Its very true that the 6 PPC is a specialty cartridge designed with 100-300 yard competition in mind. However I have seen many 400,500,600 matches won by the PPC, frequently it is in the hands of a BR shooter trying his hand at longer ranges. A 6BR with heavier VLD bullets in 8 or 9 twist barrel technically has an advantage over the PPC in this scenario but not enough to save the 6BR shooter if he makes even a small slip. These Short range 6PPC BR rifles are so good they give up very little at longer ranges especially if its not real windy and frequently they are being used by shooters with a lot of experience.
