107gn 6.5x08 How low can you go?

[lucho]

For CPT's I shoot a Sierra 107gn with 33.8gns of VV N135 in a 6.5x08 rifle.  I'm not sure how fast they are going since I haven't chronographed them yet.

How slow can I push the 107's and still be effective for CPT's?
The slow speed could also be used for a 200 yard reduced course matches or even just for practice.

I am guessing I wait them to stay supersonic out to the turkey line.

What say ye?

Yo Lucho,

If you slow down the 107's much below about 2,650 fps pig ringing becomes a problem.  At SLO I’ve seen turkeys rung when the headwind is brisk and the hit is just above leg-body junction.  Also, to accurately slow down the 107's you'd need to go to a faster powder to create enough initial pressure to seal the chamber mouth.  N130 and N133 work great for driving the 107’s in the 2,600 fps range, but pig ringing can be a problem.

If you are really serious about reducing recoil your short animal load and still have at least or better wind deflection as well as a harder hitting load for pigs, I'll give you some 140 A-Maxs and appropriate powder.  Are you shooting moly or going naked?  With 27.5 grains of N133 the A-Max will be leaving the barrel at about 2,250 fps, the same as the 6.5TCU load for C, P & T.

I'll be at the Chabot HP Silhouette match Sunday.  If you'll be there the components will be brought.

Later,

Dan
