I like 38 grns of IMR-4064 in either of my Ruger 77's. This will produce 1/4 to 1/2 inch groups @ 100 yds in my rifles with the 55 grn Nosler BT bullet or the 55 grn V-Max bullet. Now, be safe, work up, to any max loads. There is just something about the way that bolt parts your hair when it comes out that will make you study the reloading manual longer.
I have tow Swifts, one is a Remington VS and it likes a heavy dose of Varget with a Speer 50gr. TNT. The other one is a Model 70 Winchester with a Shilen barrel. It likes 50 gr. V Max with IMR 3031.
I use Federal 210 Match primers with both loads.
My swift loads are:
38.5 grains of IMR 4064 with a 50gr Nosler ballistic tip bullet
42.5 grains of AA4350 with a sierra 60 grain #1375 * favorite *
38.5 4064 under 50 VMax
34.5 Varget under 50 VMax
34.5 H335 under Midway Dogtown 55
They all went MOA or better.
Standard disclaimer, use your own best judgement. I just got a new to me Rem 700 Varmint Swift to play around with. Let the fun start again. WooHoo!!!
IMR 4064 for pills of 52 grains and under for sure.
Many like the 4064 under 55 gn blts as well, but by far my favorite 55 gn blt pusher is N550 - (my guns liked 41.4 gn w/ a Fed 210, but you'll have to work up your own.)
For 60s, N560 is really showing some promise. My PD shooting buddies in CO have been pushin 60 V-Max moly'ed pills close to 3900 fps (they say) with excellent accuracy.
Fast, hard hitting, and accurate...That's what we all like to hear!
Case stretching has always been a bugaboo to the Swift. About every 5 loadings and the cases get trimmed and annealed. When the time comes, I'm considering setting the barrel back a couple turns and having a 220AI reamer chased down the chamber.
The "AI" treatment will stop the case stretching on the Swift, reason enough to do it, especially if you have a small number of cases. But, the AI'ed Swift will push blts another 150 fps or more to boot. That can't be all bad!
A buddy of mine had two Savage 112-J's and I had two Rugers HB in Swift. We shot the barrel out of all of them using between 43.5-44.5g of AA2700 with a 50g Nosler Ballistic tip @ 4000 fps. When you get the load tweeked in in as far as charge and seating depth, it chews a single ragged hole.
The one thing that we saw is how much easier AA2700 is on a barrel compared to the IMR 4064 that we had been using.
We killed a dump truck full of chucks and jackrabbits with this load.
