243 Winchester +p

[Thejet]

Any loss of brass yet? Still using Winchester brass and 108 eldm?

Still using the 108s and just retired the Winchester brass. No failures just moving to alpha brass.

How many reloads did you get on the Winchester?

Some had 5+

Your starting load for N560 is VihtaVouri's max load. Their max velo is 2749 fps with a 23" barrel.
You don't have a 243 +p, you have a 243 + Unsafe.

VV's load data is garbage, my load in my 6.5 is 11gr over their published max and I didn't even get any signs of pressure on my ladder at 95° besides velocity increase at the highest charge. I'm a very conservative reloader and usually only go a grain or 2 over published max on a pressure test even in custom chambers, but after consulting with some experienced guys that favor VV I took their advice and it yielded great results.

Spending time with this thing lately, 3-5 reloads on the Winchester brass before scraping it. Still pushing 108s at 2850 like a champ.
New brass, powder, and new bullets 87gr Vmax just for a plinking/coyotes load to come. Should be in the 3050 range if it follows suit.

anything new?

I'm curious how this is going with the +P

Also, I forgot to ask this earlier. It looks like a factory Tikka. With the p+ throat did it lengthen the throat at all to where you can seat the 108s further out?

I throated my factory Tikka about 0.100 farther out and it shoots lights out but I don't think I was able to gain much if any velocity potential

I'm curious, will the 8-twist Tikkas fully stabilize the 109eldm?

An 8-twist Tikka would certainly be the easy-button for a light/short 6mm.

I sure hope so, I have a 6 Creed being built with an 8 twist that I want to shoot them from, lol. I haven't seen any issues though, I think 8 is fine.

I think it depends on your altitude. My 8 twist Tikka had bad results with 112 Match Burners. Handles 108 ELDMs well, but I think the 109 is closer to the 112 than the 108 (if my memory serves, I remember deciding not to try the 109s after comparing).
