Re: Left Hand Heavy Barrel Custom 7mm RM walkthrough needed
You are not going to get what your looking for at the price of a Sendero. The best option as you stated isn't available in 7mm, but for what you want the Savage 110fcp-HS in 300wm is the best option for about a grand. I'm guessing you don't reload, but you should still be able to get .75 moa with high quality ammo. Spend 175 bucks to put a break on it and it will have less recoil than a 7mm. You can also rebarrel this rifle to 7mm for less than 350. If your hunting from benched treestands, you may consider a Savage 12 f class 6.5x284 or a model 12 lrp in 260rem or 6.5 creedmore. You can always browse gunbroker and other firearms auctions for a Savage 112bvss, they were available in 7mm rm, all of these makes I listed are capable (not every rifle, just make) of .5 moa or better.
As for your 17hmr not grouping, its your ammo, rimfire ammo sucks, you may have to try 10 different brands before you find one that is decent. Good luck getting much better than 1.25moa with a factory rifle in 17hmr.
