I can't wait for mine!

Its getting sighted in tomorrow along with Dave's.

Ryan,

What is the weight of those two rifles?

 

[hkm]

I am in the process of putting my build together the question I have is should I go with a .235 or .225 free bore . I will be shooting Berger 230 and 215.

 

[IdahoCTD]

My reamer has a .235" throat and you have to seat 215's out a bit and 230's in a bit. Mine shoots 230's better than 215's.

Ryan,

What is the weight of those two rifles?

The one with the eh1 and super light cheek piece was probably right at or a little under 11lbs w optics. The dbm setup is a bit heavier than a bdl setup. The PRS stock was a bit heavier due to the heavy cheek piece version. The elite cheek piece is 18 oz lighter than the one that's built into the stock. I have all the parts instock for builds right now with a lead time of 4 months or less. Come February/march im usually booked through august/September. Everybody orders rifles at that time to get them before hunting season.

Are you able to load down and keep the accuracy? Would love to have a super-accurate min load around 70 grains for shorter ranges & less throat erosion, while keeping the full loads for going long. Possible/advisable? Or do I need a 300 WSM and a Norma Imp?

 

[IdahoCTD]

I'd do both . I have 3 300wsm and will have 3 300 Norma Imp's soon so I might be bias both directions

Guys,
These rifles shoot as good as they look. Light fireforming loads with the 230 Berger went into one hole at 100 yards with the 25X scope shooting off a bench with the bipod. I'll keep this thread updated as I work up a load.

Ryan,

What was the velocity with that H1000 load?

 

[rpierce]

Ryan,

What was the velocity with that H1000 load?

3080-3100 roughly. Its a stupid accurate mid range load. However I never got the es and SD to be anywhere that of my n570 load. I loaded up 500 rounds w h1000 to test fire rifles with. Was way cheaper to load em up with h1000 vs VV N570 LOL. My n570 load will have an SD of 6-8 for 20+ shots. its completely dialed in to a long ways out there. Hits perfectly for vertical everytime on the targets. All I have to worry about is wind, LOL.

My experience with N570 and 215gr Berger in the 300 NMI is the same. Vertical with 570 is by far the most consistent I've seen from all the testing I've done. Its also the most temp stable powder I've ever used so far. Shot it in 40 degrees difference of temperature with absolutely zero change in average speed, POI, or vertical on target (all load testing @500 yards)

Anyone running 250 A tips? Curious about real world velocities in an improved chamber.

Not that Im aware of. Plug the info in to a ballistic calculator and youll see that theres really no advantage over the lighter bullets due to the substantial velocity loss w the 245 berger and 250 a tip.

I think I've just found my next rifle build. Absolutely bada$$ build, been wanting a magnum caliber for a while and this will be it. Thanks for posting.
