This is a long range hunting forum and SP6x6 has an impressive LR Elk collection, who gives a sh_t if this is an ELR thread.
How many elk have you taken..
While agree with you on your sentiment, Len has rules for the ELR forum. I think he wants experts and guys pushing their limits to share their knowledge and keep the banter at a minimum.
Anyway, now that's out of the way, I would love to shoot ELR, but I haven't had the opportunity yet.
To answer your question. I have 4 high quality stocks. I have the manners T4A on a GAP 6.5CM, a manners TA on a Bighorn .308, a manners T3 on a Remington 700 PTG one piece bolt .338 Lapua Mag, and an HS precision on my 6.5CM GENII 5R.
I am super happy with my manners. The MCS TA is probably my favorite, since it's carbon fiber (lighter), has the adjustable cheek piece, and it's still comfortable and easy enough to plop down behind pretty quickly.
The T3 is nice but I have to use low scope rings since the cheek piece isn't adjustable. The T4A is AWESOME but it's not as easy to get into position quickly as it is with my TA. So I have 3 hunting style stocks and one tactical / comp stock. They have their pluses and minuses. The one down side is once you go manners, it's hard to go back to any other stock.
With chassises, I tried them out. I wasn't a fan. Reminded me too much of being behind an AR. If I want the feel of an AR, I'll just shoot one of my ARs. Lol
Post pics of your .375 when it's done. Sounds awesome!
And for the record you can take the .308 out pretty far. Guys shoot 1200 with the .308 which I would call ELR shooting.
