Re: bearing lengths.

You need two comparators, one to pick up at the start of the ogive and one to pick up at the start of the boat tail. Simple actually. Bearing lengths vary considerably from batch to batch, be they Berger, Sierra or anything else, and this variation does affect exit speeds, AND available case capacit...

Re: Powder choice

With Bergers and 2208 start at 45.5 and work up. For 1000yards you need around 2940 /2950 and should be able to get this with around 46.5 gns Depending upon your chamber ( free bore ) and projectile Base to ogive measurement, using Lapua cases you might get to 46.5 without compressing. If you cannot...

Re: Powder choice

2208 is as slow as you would want to go. Start at 45.5 gns and work up. Sierras ( 2156 ) need to go at around 2940 minimum if you intend shooting 1000yards. If you are using Sierra 2155 bump it up to 2970.MInimum, however these could need a load around 47gns which may be too much for a lapua case de...

Re: Windreading Performance Comparison

Further to the above --if you want to make a comparison then put an FS shooter on a bipod down with a TR shooter and let them shoot Bisley style in 45 sec/shot.Then you have some sort of equality.

Re: Windreading Performance Comparison

Pretty much impossible to make such a comparison. Closest comparison would be TR and FS shot off a bipod. FO is a discipline alone as is FTR by virtue of ammunition. Even trying to compare say FS shot off a bipod to FS off a joystick rest is difficult for obvious reasons. I would put my money on a T...

Re: Ogive to base measurement.

What does "ogive to base " prove after all? It does not necessarily consistently fix seating depth of a loaded round. That depends upon the diameter at which the seating cone picks up the projectile. I have seen projectiles from different batches with the same " base to ogive " b...

Re: Which caliber to ahoot for new shooter

True that rifles all cost about the same, but then --
Big variations in cost in what you put on top and underneath. -- for example a $1200 Leupold or a $4000 something else.
a $200 bipod or a $2000 plus rest ?
Don't see the level playing field there.
FTR is about as level as it gets.

Re: Handicap system

Your first sentence covers it Alan. But,there is no good handicap systems,--too many variables. 300 yard handicaps are no good for 900 yds and vice versa -as an example. There are many other variables. Some competitors ( at club level ) actually do shoot to maintain high handicaps, as David said. Ag...

Re: Handicap system

Does handicap work any better than grading? Problem with handicap systems is that when the maximum score is reached by more than one competitor a result is usually determined by percentage of handicap saved --big mistake as in 99.5% of cases the scratch shooter wins --handicap system is therefore de...

Re: Testing the Testing

All this concern about case capacity variation can be easily checked. ( 308 anyway ) Simply load some Winchester cases and check against either Lapua or ADI cases with the same load specifications. The difference between these cases is around 1.5 grains powder weight /capacity. Lapua is about 1.5 la...

Re: Testing the Testing

Try spherical powder-- granule size is down to around half a mm --gives very consistent case volume measurements.
Use spent primers in backwards.
